The transmission works with the engine to provide power to you car’s wheels. Whether automatic or manual, the transmission plays a major role in the overall performance of your car. Make sure to check it at the first sign of problems.

A transmission/transaxle keeps the engine’s output optimally matched to the speed and load conditions. The torque converter, connected to the automatic transmission/transaxle input shaft, connects, multiplies and interrupts the flow of engine torque into the transmission. Universal and/or Constant Velocity (CV) joints connect to the driveshaft to transmit output power from the transmission to the rear axle on rear-wheel-drive cars and the front axle on front-wheel-drive cars. These joints also allow the driveshaft and/or CV shaft to work at an angle. The several different types of automatic transmission fluid serve multiple purposes: cleans, cools, lubricates, transmits force, transmits pressure, inhibits varnish buildup and continually protects the transmission.

Typical Wear and Tear
Wear and tear on the transmission can be influenced by:

• Driving habits
• Towing or excessive loads
• Operating conditions
• Condition of the transmission fluid
• Frequency of regular maintenance

Symptoms

• Slipping
• Hesitation
• Bucking
• Grinding gears
• Difficulty shifting

What is it?
Your car’s exhaust system has come a long way from the old days of exhaust pipes and mufflers. Today, the exhaust system is safety and emissions control rolled into one. Have your car’s exhaust system inspected regularly and check it immediately if you suspect any problems.

What does it do?
The exhaust system routes dangerous exhaust gas from the engine out and away from the car to keep from affecting the occupants. Next, the exhaust system reduces exhaust noise from the engine. The catalytic converter reduces the level of harmful pollutants in the exhaust. The oxygen sensors mounted in the exhaust system monitor the level of oxygen in the exhaust gases to maintain efficient engine operation and to monitor the converter’s operation.

Typical Wear and Tear
Maintain a safe car with regular exhaust system checks. Factors that affect replacement requirements include:

• Driving habits (short trips take their toll on exhaust system life)
• Road conditions (salt, road spray, bumps)
• Vehicle type
• Age of exhaust system parts

Symptoms

• Loud noise
• Rattling noise when starting, accelerating or braking
• Drowsiness while driving
• Rotten eggs smell

What is it?
Your car’s brake system is its most critical safety system and you should check it immediately if you suspect any problems. A properly operating brake system helps ensure safe vehicle control and operation under a wide variety of conditions.

What does it do?
When you push the brake pedal, the force generates hydraulic pressure in the master cylinder. This pressure flows through the hydraulic lines and hoses to the wheel cylinders and calipers, forcing the shoes against the drums (drum brakes) and the pads against the rotors (disc brakes). The resulting friction slows the vehicle and is relative to the amount of force applied at the brake pedal.

Typical Wear and Tear
Brakes are a normal wear item for any car and eventually they’re going to need replacement. Avoid letting your brakes get to the “metal-to-metal” point, which usually means rotor or drum replacement. Factors that affect wear include driving habits and quality of brake pads and shoes.

Symptoms

• Car pulls to one side during braking
• Pulsating brake pedal or steering wheel shake
• Brake pedal feels “mushy”
• Unusual noise when you step on the brake pedal
• Repeatedly need to add brake fluid to the master cylinder
• Brake fluid sprayed onto outside of wheel
• Unusual odor or noise

Your car’s belts and hoses are essential to the cooling, air conditioning and charging systems, and the engine. Don’t take these routine replacement intervals for granted because they can break down and leave you stranded.

The timing belt keeps the crankshaft and camshaft mechanically synchronized to maintain engine timing. Whether serpentine, V-belt or fan belt (the belts on the outside of the engine), they all transmit power from the front of the engine to accessories that need to be driven, such as the air conditioning, the charging system and fans. Radiator and heater hoses carry coolant to and from the engine, radiator and heater core.

Typical Wear and Tear
Key items that affect the replacement interval for belts and hoses:

• Vehicle age
• Electrolytic corrosion
• Mileage
• Oil contamination
• Belt tension
• Failed hose clamps

Symptoms

• Squeaking noise from under the hood during start-up or operation
• Coolant leaks
• Dashboard light will illuminate
• A/C System may fail
• Engine overheating
• Smell of burnt rubber

Your car’s filters are important to the longevity of your car and interior comfort. Maximize your car investment by replacing filters regularly.

The oil filter traps contaminants, allowing the oil to flow through the engine unrestricted. The fuel filter separates harmful contaminants that may cause problems with carburetors or intricate fuel injectors. The air filter traps dirt particles, which can cause damage to engine cylinders, walls, pistons and piston rings. The air filter also plays a role in keeping contaminants off the airflow sensor (in fuel-injected cars). The cabin filter helps trap pollen, bacteria and dust that may find their way into a car’s ventilation system. Many people don’t realize they have this filter.

Typical Wear and Tear
Filters are normal wear items that require regular checks and replacement. Factors that affect replacement intervals include:

• Mileage
• Driving habits
• Driving and road conditions
• Type of filter
• Vehicle type

Symptoms

• Poor gas mileage
• Hesitation while accelerating
• Musty odor in the cabin

What is it?
Your car’s emission system keeps the engine running cleanly and efficiently in all sorts of operating conditions. A steady or flashing warning light on your vehicle dashboard indicates a problem that is currently happening and may require immediate attention. Failure to do so can reduce your gas mileage or cause your vehicle to pollute.

Your car’s emission system controls the emissions, exhaust and pollutants (including gasoline vapors escaping from the fuel tank), using an array of sensors, computerized engine controls and the exhaust components. The emission system substantially reduces harmful gases such as carbon monoxide (CO), unburned hydrocarbons (HC) and oxides of nitrogen (NOx) and, by law, must be maintained in operating condition.

Typical Wear and Tear
Some factors affecting the emission system include:

• Driving and atmospheric conditions
• Mileage
• Vehicle age
• Type of spark plug electrode material
• Poor vehicle maintenance
• Poor quality fuel
• Damaged or worn sensors
• Dry-rotted or cracked vacuum hoses

Many people don’t realize the importance of the fluid flush for their vehicle. Proper fluid flushes save car owners thousands of dollars over the life of the vehicle. Flushes prevent rust build-up inside the lines that transport the fluid. The master cylinder can fail and brake calipers and wheel cylinders can stick. Flushes also limit hose fatigue. These types of issues can happen with all your fluids, including: power steering, differential, clutch and transmission. Flushes can even prevent costly transmission replacement.

Unfortunately, we have found that not all repair shops are providing proper fluid flushes. The industry has referred to these as “drain and fills”. A proper flush is different than a drain and fill in a number of ways. A proper flush is done at regular intervals based upon climate and amount and type of miles driven. It includes cleaning out areas that trap the fluid, like a brake or clutch reservoir. It doesn’t make sense to leave the dirt in these areas and put new fluid in. The fluid will simply become contaminated with the next start-up.

An example to further demonstrate the difference follows. Draining and filling a cooling system requires draining a radiator of it’s fluid. What comes out is about 50% of the system’s capacity. This requires a technician to replace what came out, again 50% of the fluid. Now, you have 50% contaminated fluid and 50% new fluid. What will happen to the new fluid? The new fluid mixes with the old and is contaminated. So, you paid for a service and you still have dirty fluid in your system. The proper way is to flush the system thoroughly with water. This will remove all fluid from the engine, heater core, radiator, water pump and hoses. When the new fluid is added, it is clean and remains so. We do not recommend long-life coolant in any vehicle. It is toxic to the system.

Here at MARS Mobile Auto Repair Service, we always take the additional time to complete a proper fluid flush. A small amount of preventive maintenance through regular fluid flushes can save you a great deal of money down the road.

Get ready for that vacation road trip!

Perform a basic safety check. Routine car care like tune-ups, battery checks, and tire rotations are important and help with preventing breakdowns. That said, if you’re traveling long distances this summer, don’t just rely on your usual maintenance. Be sure to also check your vehicle’s tire pressure, wiper blades, fluid levels and fluid condition, lights, and air conditioning before you go.

Check for recalls. Even the most informed car owner may be unaware that their recalled vehicle is in need of repair. NHTSA’s free VIN Look-Up Tool lets you see if your vehicle has been repaired as part of a safety recall in the last 15 years.

Protect your passengers. All drivers and passengers should wear seat belts. When you’re traveling with a child, it’s safest for them to ride in a car seat suited for their age and size, and all children 13 and younger should ride in the back seat.

Share the road and stay alert! Warmer weather will attract different types of roadway users, including motorcyclists, bicyclists, and pedestrians. Without the protection of a car or truck, these road users are more vulnerable. So put a safe distance – 3 or 4 seconds worth – between you and motorcyclists, and always be mindful of pedestrians or bicyclists. During long trips, take a break when driving long distances. Plan ahead for times to stop and stretch, eat healthy meals and relax, and consider stopping and staying in a hotel to recharge during longer drives.

Store an emergency roadside kit. Even well maintained vehicles can break down, so it’s a good idea to have a few emergency items readily accessible for your family’s road trip. In your kit, consider adding a cell phone and charger, first aid kid, flashlight, flares, jumper cables, water, and blankets. Even if you don’t have to use your kit, you’ll have peace of mind knowing that you have these critical items stowed in your cargo.

Don’t drink and drive. An average of 1 alcohol-impaired driving fatality occurred every 51 minutes in 2015. Be responsible, and don’t drink and drive. If you plan to drink, choose a designated driver before going out. You can also get NHTSA’s new SaferRide mobile app. SaferRide allows users to call a taxi or friend for a ride, and will even help users identify their location so they can be picked up.

Avoid distraction. Distraction accounts for approximately 10 percent of fatal crashes and 15 percent of injury crashes. Distracted driving can be anything that pulls your attention away from driving, including cell phone use, texting while driving, eating, drinking, and using in-vehicle technologies and portable electronic devices.

Observe “Move Over” Laws. Move over and change lanes to give safe clearance to:  law enforcement officers assisting motorists, tow trucks, maintenance crews and of course, your very own mobile mechanic on the side of the road. It’s the law in all 50 states.

Does your car have suspension problems?

How can you tell?

Here are some symptoms you will notice:

“nose dives” when braking (it leans forward)

“rolls” to the side when cornering (it leans side-to-side)

“squats” during acceleration (it leans backward)

Suspension components, including springs, shock absorbers (or struts on some vehicles), anti-roll bars, control arms and other parts, are like combat troops serving on the front lines: They take a pounding daily from pock-marked streets, railroad tracks, rain, snow, road salt, gravel, all manner of dirt and grime, and the occasional piece of scrap metal or other debris that drivers see too late to avoid.

Under those conditions, just about any suspension component can be damaged or worn out from years of abuse, resulting in a number of symptoms and/or noises that should be your wakeup call to see a car doctor. Here are some common issues vehicle owners are likely to encounter:

• Poor wheel alignment: The wheels have to be pointed in the right direction (literally) and aligned for toe-in, camber and caster. If they aren’t, your steering won’t be centered when you’re going straight and tire wear will increase. Wheels get knocked out of alignment by potholes and curbs, but getting the wheels aligned won’t fix damaged springs, controls arms or other parts that affect alignment. When you buy new tires, it’s a good idea to have the alignment checked so suspension issues don’t shorten tread life.
• Shock absorbers:They really should be called “dampers,” and when they wear out you should notice more bouncing after a bump and a whole lot of shaking going on over rough roads because they can’t keep the tires planted on the pavement. Shocks contain fluid that dampens the bouncing, and once they start to leak, performance will deteriorate.
• Springs:These are what hold the weight of the car, and as they wear they can sag or break. If your car is on level ground but one corner is lower than the others, that’s a sign of a damaged spring. You can measure the height of the corners to confirm your visual cue. You might also hear clunking noises over bumps, and the car may not corner with confidence because a damaged spring can’t control the weight it’s supporting.
• Ball joints: These are pivot points that attach the suspension to the wheels, and they absorb some of the shock from up-down movement and rotate as the steering angle changes. You’ll know they need replacing when you can hear them squeaking and creaking, especially when turning. You’ll know you waited too long if a ball joint breaks and suspension parts are dragging on the pavement. A mechanic can tell if they need replacing by the amount of wheel movement they can force by hand or, in some cases, by wear indicators on the ball joints.
• Control arms:These are hinges that hold the wheels to the frame and connect the steering to the wheels, so when you turn one the other responds. Lower control arm bushings are more prone to wear out on front-wheel-drive cars than on rear-wheel-drive cars. Bushings are rubber and/or metal parts that help absorb shock, and when they wear they can cause ride and handling problems and accelerate tire wear. So can a bent control arm. Signs of wear include clunks or rattles — because the wheels move back and forth in acceleration and braking — and loose, imprecise steering.

The steering and suspension systems are key safety-related systems that largely determine your car’s ride and handling. Have these systems checked regularly, at least once a year and usually with a wheel alignment.

The suspension maintains the relationship between the wheels and the frame or unibody. The suspension system interacts with the steering system to provide vehicle control. When working properly, the suspension system helps absorb the energy from road irregularities such as potholes and helps to maintain vehicle stability. The steering system transmits your input from the steering wheel to the steering gear and other steering components to control the car’s direction.

Typical Wear and Tear
Over time, steering and suspension components wear out and require replacement. Regular checks are critical to maintain a safe car. Factors that affect wear include:

• Driving habits
• Operating conditions (potholes in road-hey, like we have in WI!)
• Vehicle type
• Type of steering and suspension system
• Frequency of regular maintenance such as chassis lubrication and wheel alignment

Symptoms

• Car pulls to one side
• Uneven tire wear
• Excessive noise, vibration or bouncing
• Loss of control

You car’s fuel system works with the rest of the engine control system to deliver the best performance with the lowest emissions. Check your car’s fuel system regularly or immediately if you smell gas or suspect a problem.

The fuel system transfers fuel from the fuel tank and passes it through a fuel filter for straining before it arrives at the injectors. A pressure regulator controls fuel pressure to ensure good engine performance under a variety of speed and load conditions. Fuel injectors, when activated, spray a metered amount of fuel into the engine. Some vehicles use a return line system to return unused fuel back to the tank.

Typical Wear and Tear
Intervals for fuel system maintenance may be influenced by:

• Fuel quality
• Vehicle age
• Mileage/time
• Operating conditions
• Maintenance history

Symptoms

• Poor fuel economy
• Vehicle won’t start
• “Check Engine” light is illuminated

What is it?
The engine cooling system affects your car’s overall dependability and engine longevity. Cooling systems have declined over the years with new coolant formulations and new radiator designs and materials. If you suspect a problem with your cooling system, you should check it immediately.

What does it do?
The key parts of the cooling system remove heat from the engine and automatic transmission and dissipate heat to the air outside. The water pump circulates coolant through the engine. The coolant absorbs heat and returns it to the radiator where heat is dissipated. The thermostat regulates the coolant temperature to keep it consistent for efficient engine operation.

Typical Wear and Tear
Factors that affect the replacement of cooling system parts include:

• Driving habits
• Operating conditions
• Type of vehicle
• Type of coolant
• Frequency of regular maintenance such as coolant changes

Symptoms:

• Overheating
• Sweet smell
• Leaks
• Repeatedly need to add fluid

Reminds me of Mike, when he was growing up in the 70’s. Although, that would have been his Big Wheel being repaired from the millions of wheelies and jumps.

Its so hot…

-you actually burn your hand opening the car door.

-you leave a layer of skin on the car seat.

-My Reeses’s wrapper now reads, “Melts on your car seat, not in your hand.”

-you need an oven mitt to handle your seat belt.

-I used my dash to heat a bag of microwave popcorn.

A motorist, after being bogged down on a muddy road, paid a passing farmer twenty bucks to pull him out with his tractor. Afterward, he said to the farmer, “At those prices, I should think you would be pulling people out of the mud night and day.”

“Can’t,” replied the farmer. “At night I haul water for the hole.”

Jill’s car was old and unreliable and she called John for a ride every time it broke down. One day John got yet another one of those calls.

“What happened this time?” he asked.

“My brakes went out,” Jill said. “Can you come to get me?”

“Yeah, all right, where are you?” John asked.

“I’m in the drugstore,” Jill responded.

“Okay, and where’s the car?” John asked.

Jill replied, “It’s in here with me.”

Me: *on the phone with my mechanic* “Do you do body work?”

Yesterday, I had a flat tire on the interstate. So I eased my car over to the shoulder of the road, carefully got out of the car and opened the trunk.

I took out two cardboard men, unfolded them and stood them at the rear of my car facing on-coming traffic. They looked so life like you wouldn’t believe it! They’re dressed in open trench coats that exposed their nude bodies and private parts to the approaching drivers.

But to my surprise, cars started slowing down to look at my lifelike men. And, of course, traffic began backing up. Everybody tooted their horns and waved like crazy. It wasn’t long before a state trooper pulled up behind me.

He got out of his car and walked towards me. I could tell he was not a happy camper!

“What’s going on here?”

“My car has a flat tire,” I said calmly.

“Well, what the hell are those obscene cardboard men doing here by the road?”

I couldn’t believe that he didn’t know. So I told him, “Helloooooo, those are my emergency flashers!”

Find out here if you need new shocks or struts.  There are telltale symptoms.  Worn suspension parts can also damage your tires by causing uneven wear.

What you can’t see

Automotive batteries come in many shapes and sizes, but their operating principles are remarkably similar. The modern automotive battery is a lead-acid storage design. In short, it’s an electrochemical device that converts chemical energy into electrical energy. When the battery is placed under a load, such as when the ignition is switched on, the device converts stored chemicals into electricity, and the current flows through the wires to its destination. read more…
