ENGINE MAINTENANCE

Your engine is one of, if not the most important major component of your car. Without it working in good order, it's impossible for you to go anywhere. If it runs inefficiently, you may face a whole host of problems that can be avoided with relatively simple maintenance. At Lou's Wolverine Transmission and Auto Repair we provide all of the expertise and parts needed to keep your engine running happily and at peak efficiency.




Oil Changes
One of the simplest ways to determine the condition of your engine is to examine the oil that drains out during an oil change. The oil circulates through much of your engine, so it's a great way to determine the overall health of your car's power plant. Ideally, we want your oil to be darker than when it went in with uniform viscosity and no solid particles. Solid particles are a major concern because they mean that something inside the engine, be it a seal or anything else, is breaking apart. Engines contain a lot of finely balanced mechanisms with only a few micrometers of space for moving parts to clear each other. Any solid particles moving through your engine can cause a massive amount of damage very quickly. At Lou's Wolverine Transmission and Auto Repair we perform expert analysis on your oil to make sure that everything is working perfectly within your engine's internals, and we carry the best oils to replace that fluid in your vehicle.


Engine Coolant
Another simple item that can save your engine untold misery, is the coolant fluid, which keeps everything running at the correct temperature. The many moving parts inside your engine, as well as the explosions taking place within its combustion chambers, generate a significant amount of heat. As with any machine, your engine has temperature tolerances at which it happily operates. Once those tolerances are exceeded, things can start to go wrong. A common side effect of overheating can be radiator failure. The water that cools the engine becomes heated and pressurizes the radiator past a safe level causing the scalding water to spray out. This dangerous problem can be avoided with the engine coolants used by Lou's Wolverine Transmission and Auto Repair.


Filters
To work efficiently, your car's engine needs the ingredients for combustion to be delivered in the purest form possible. To this end your engine contains a number of filters which keep everything nice and clean. Lou's Wolverine Transmission and Auto Repair's engine thorough maintenance keeps checks on your air, oil, and fuel filters, replacing them as needed to keep your car running at its highest efficiency.


Fuel Injector Cleaning
Working alongside your spark plugs are the injectors that shoot a precise amount of fuel into the combustion chamber. Over time these injectors can become clogged with contaminants from fuel. Lou's Wolverine Transmission and Auto Repair carries a line of specially developed injector cleaning solutions which open the injector tubing back up and get your car back to making the most power that it can.


Accessory Belts
Engine accessories such as the alternator and air conditioning compressor rely on belts that take power from the engine to run them. Over time, these belts can become frayed and damaged. If your alternator belt snaps, for example, your engine won't be able to generate the electricity it needs to charge the battery and keep itself running. Lou's Wolverine Transmission and Auto Repair can keep a close eye on the health of your accessory belts and ensure that all your engine's pulleys are lined up perfectly to allow for the maximum amount of use from your belts.


Diesel
Although diesel engines don't require tune-ups and tend to last longer than gasoline engines, they do require regular maintenance. Typical maintenance tasks include:

  • Changing the oil & filter
  • Changing the air filter
  • Changing the fuel filter
  • Bleeding the fuel system
  • Draining the water separators
  • Refilling the urea injection system

You can count on the experts at Lou's Wolverine Transmission and Auto Repair to help your diesel engine last a long time.

Fuel Injection
Fuel injection is a system for admitting fuel into an engine. Since 1990, fuel injectors have completely replaced carburetors as the primary means of getting gasoline into the engine. A fuel injector atomizes the fuel by forcibly pumping it through a small nozzle (under high pressure). Failure of the fuel injection system means poor performance and ultimately destroys the engine. Make sure your vehicle's fuel injection system is maintained properly. For all your fuel injection maintenance and replacement needs, call 734-663-3314 or visit Lou's Wolverine Transmission and Auto Repair today.

Ignition
An ignition system is a system for igniting (using an electric spark) a mixture of fuel and air in a gasoline engine. A properly working ignition system means a properly starting engine and high performance from your car. For all your ignition system maintenance and replacement needs, call or visit Lou's Wolverine Transmission and Auto Repair today.

Ignition Wires & Cables
Ignition cables also known as spark plug wires are an important part of your car's ignition system. They transfer the spark from the ignition coil to spark plugs that ignite the mixture of fuel and air. The mixture starts the engine. Over time, ignition wires and cables get weak and break down. This makes it impossible for the spark to reach the engine cylinders. This results in the engine misfiring. The car will eventually fail to start. If it does start, it will run poorly. Common symptoms of faulty ignition cables and wires are: poor gas mileage, engine misfires, engine light is on, and engine may vibrate. If your car needs new ignition cables and wires, call or visit Lou's Wolverine Transmission and Auto Repair in Ann Arbor, MI 48104. Here, you will have the wires and cables changed by a top-rated mechanic.

Spark Plugs
A spark plug delivers electric current to the combustion chamber from the ignition system. Spark plugs that haven't been changed for a long time can cause ignition problems. At Lou's Wolverine Transmission and Auto Repair, we have automotive experts who will check and replace your spark plugs. For all your spark plug repair or replacement needs, call 734-663-3314 or visit Lou's Wolverine Transmission and Auto Repair today.

Oil, Lube, and Filter
To keep running smoothly, your car highly relies on oil, lube, and oil filters. Oil helps in lubricating, cooling, and cleaning the internal engine components. With time, motor oil becomes contaminated. Your car needs an oil, lube, and filter change every three months (or 3,000 miles). When it is time for a lube, oil, or filter change, take your vehicle to Lou's Wolverine Transmission and Auto Repair in Ann Arbor, MI 48104.

Check Engine Light
No one likes to see their car's "Check Engine" light come on. The light could mean a costly problem, like a bad catalytic converter, or it could be something minor, like a loose gas cap. At Lou's Wolverine Transmission and Auto Repair, we can pull the code and diagnose the problem for you. Give us a call at 734-663-3314 or stop by the shop for our expert assistance.

Whether you're in need of simple oil service, or more significant engine maintenance, call Lou's Wolverine Transmission and Auto Repair at 734-663-3314 to learn how we can help you get back on the road quickly!


What Our Customers Are Saying

Lou and his team are unbelievable. Not only do they do incredible work but they are also incredibly fair and will have no problem telling you what should be done rather than what will make them the most money. They really care about the customer. That's why my family and I refuse to go anywhere else for service. Lou is the only place to go, in my opinion.


-Jonathan B.

Lou did a great job on my truck! He was very professional and punctual in working on my vehicle and getting it back to me in a very timely manner. I found his prices to be reasonable. I appreciate his keen insight in addressing all of my concerns, without any additional charge. I will be going back to him and highly recommend this place!


-J. C.

If you're looking for a good auto shop that specializes in transmissions and drivetrains, stop searching. Not only did they fit me in on a busy afternoon, but they returned my car same day, fixed the issue I was experiencing with my AWD subie, and did it all at a fair price. No surprises, no additional services, just a solid experience. I can see why Lou's has been an Ann Arbor institution for 20 years.


-L & J

Great prices and amazing service. Not just transmission work but all maintenance. Thanks again


-Stuart K.

Dan is a great guy who treats you fairly.


-Mike B.

Took my Buick there with transmission problems They were very upfront, helpful. They've been there forever and had great reviews. And with good reason. They do quality work and know what they are doing. Will try other things before overhauling if they have a chance to fix it. In my case a Trans flush & cooler (Very reasonable price to do it and I wanted to have one anyway). Trans was OK for a while but went back to not shifting right. The did a complete overhaul and at less than I feared. What are you gonna do? You can't throw away the car... Other repair places offered to do it but if I was going to do it I wanted someone that did it every day. Very happy with them and glad they are here in town. Oh, I didn't know as a Veteran I got a discount but they saw my Military licence plate and gave it to me without asking. That's Honest!


-Gary D.

Lou's staff from front end to back in the shop is PHENOMENAL. They treated me with the utmost respect and were nothing short of honest and transparent the entire time. Even after I paid for a complete transmission rebuild and still had problems with my 2009 Equinox, they held onto my car until they were sure they had made it right - free of charge. I would recommend their services to anyone with transmission issues.


-Kyle B.

Lou (and now Dan) always take care of me. Honest and quick. Thanks guys!


-Frank T.

I love the guys at Lou's! Dan always goes out of his way to help me save money and provides amazing service. Being a female, I have a hard time dealing with shops because people assume I don't know anything about cars and I've lost count how many times someone tried to pull the wool over my eyes. I know I can trust Don and the guys. They get you in and out and the pricing is beyond reasonable. I won't take my car anywhere else!!


-Leigh S.

Lou retired. The business is now owned by his Nephew, still out standing service and will still continue to use for repairs I'm unable to do myself or don't have the equipment to do. I had a second vehicle that had trans axle problems around January of 2018 and I took it into him. In 2013 I had the transmission for my 1998 ford ranger rebuilt. Two years latter, the transmission is still going strong.


-John N.

Had a catastrophic failure on the transmission of my old Explorer. It honestly looked like it might be totaled. Had it towed to Lou's, they jumped right on it (even though it was the Friday before Christmas). Replaced the leaking cooling lines, verified the tranny was still good and had me back on the road in just a few hours. Life savers.


-Kent K.

Lou got my trans replaced in my Super Duty in less than a week! My truck drives like a champ now, I cannot recommend him enough! Was straightforward, less expensive, and quicker than any other shop!


-Jeremy H.

Lou's has been GREAT to me every time Lucille (my car) has needed repairs. Courteous, friendly, knowledgeable & just good people work there. Rebuilt my transmission a year ago & she's still running good. No complaints whatsoever about Lou's.
