Differential Service at AutoSurgeonInc: Viva la Difference

Posted September 26, 2016 8:48 AM

Every vehicle on Michigan roads has a differential, and it is important to the proper operation of the vehicle.  But most Lansing residents don't have a clue what it is.

The differential compensates for differing wheel speeds. For example, when you turn, the inside tire on the turn travels a much shorter distance than the outside wheel. So the inside wheel of the vehicle must move at a slower speed than the outside wheel. Without a differential, the wheels would hop and scrape while turning.

Have you ever seen the large bulge in the middle of the rear axle of a truck? That's the differential. In a rear-wheel drive vehicle, the differential is located on the back axle. Four-wheel drive vehicles and SUV's have differentials on both the front and the rear axle.

You might expect that the differential is located on the front axle of a front-wheel drive vehicle. You'd be right. But the differential is called a transaxle on a front-wheel drive vehicle because its location allows it to be combined with the transmission.

In an all-wheel drive vehicle, an additional differential or transfer case is located between the front and rear axles. Differentials are strong: They have to be because of the job they do. But those tough parts need proper lubrication. You don't want your differential to seize up. That results in damage to your vehicle.

So you need to have your vehicle differential serviced regularly. It's not a complicated job. At AutoSurgeonInc in Lansing, we've been servicing differentials for years. The used lubricating fluid is simply drained and then replaced. Some vehicles require specific additives in the differential fluid; your Lansing service center will ensure you are getting what your vehicle needs.

The intervals in time or mileage for servicing your differential vary greatly from vehicle to vehicle. Check with your owner's manual or AutoSurgeonInc service advisor to find out how often your vehicle differential needs to be serviced.

What Is That? Check Engine Light Service at AutoSurgeonInc

Posted September 18, 2016 8:32 AM

Okay. You went to your local Lansing car wash, and while your vehicle was under the dryer, the Check Engine light started flashing. Panic! What did you just do? Something is seriously wrong with the vehicle! You head for the nearest Lansing service center, but on the way, the Check Engine light stops flashing and just glows red. Hmm. Maybe things aren't as bad as they seem. You decide to wait until payday to take your vehicle in to get serviced. In the meantime, the Check Engine light goes off. What? You decide the light must be faulty; maybe when it comes on it doesn't mean anything, or maybe it's just in your vehicle as some sort of scam to get you to pay for unnecessary repairs. You're glad you didn't take your car to the Lansing repair shop and resolve to ignore that Check Engine light in the future.

Whoa! Let's look at what really happened. Your vehicle was under an air dryer. Your air intake sensor measured too much air running through the engine. It sent its report to the engine computer, where a warning was triggered; there shouldn't be that much airflow when the vehicle engine is idling. This is a serious problem that could cause permanent engine damage. Warning! The Check Engine light starts flashing, letting you know you need to take immediate action to prevent that damage.

You drive out from under the dryer, and the air intake sensor sends a new message to the computer. The computer realizes that everything is normal and tells the Check Engine light to stop flashing. The vehicle doesn't need immediate attention; but there was a problem, and it should be checked out by your AutoSurgeonInc service advisor. After a few days the computer senses that the problem is gone, so it turns off the warning light.

You may think this story illustrates the uselessness of a Check Engine light, but you should remember that a computer can't think for itself; it can only follow its programming. It doesn't know the difference between a car wash air dryer and a serious malfunction in your vehicle engine. That doesn't make it useless. It just means you have to be the smart one.

Being smart doesn't mean ignoring your vehicle Check Engine light. It lets you know when something is wrong, and you can prevent a lot of damage to your vehicle by paying proper attention to it.

Your engine computer is constantly collecting data about what is going on inside your vehicle engine. It knows what parameters are normal and when a reading may indicate a problem. It uses the Check Engine light to let you know when something isn't right. It then stores a code in its memory — which a technician can retrieve — that indicates which reading was abnormal.

The technician uses this code as a starting place to find out what's wrong with your vehicle. It's like going to the doctor with a fever. The fever is the reading that is abnormal — your temperature is too high — but the doctor still has to figure out what's causing it. It's probably an infection, but what kind? Sinus infection? Appendicitis? Flu? The problems and their solutions are quite different. But a fever also tells a doctor what's NOT wrong with you. Fevers don't accompany stress headaches, ulcers or arthritis, so there's no sense in testing for those conditions.

The pros at AutoSurgeonInc respond to a trouble code in your vehicle's computer in the same way. The code doesn't say exactly what's wrong, but it does give the technician a good indication of where to start looking —and where he/she doesn't need to look.

Now, you wouldn't consider diagnosing yourself with a serious medical problem — good medical advice unless you're a doctor. So you shouldn't consider trying to diagnose your vehicle's troubles by yourself — good auto advice unless you're a trained mechanic.

There are cheap scanners available on the market, and some Lansing auto parts stores offer to read trouble codes from your vehicle engine's  computer for you. But these are really not good alternatives to taking your vehicle to a qualified service center such as AutoSurgeonInc in Lansing. Your engine's computer has both short-term and long-term memory, and there are some codes that are specific to a particular make of vehicle. Cheap scanners can't read an engine computer's long-term memory nor can they interpret manufacturer-specific codes. That's why our manager at AutoSurgeonInc spends a lot of money on high-end diagnostic tools.

It's as if you had a choice between a doctor who had a tongue depressor and a thermometer and one who had all the latest medical diagnostic equipment on hand. Honestly, which would you choose?

Getting your codes read at your Lansing area auto parts store isn't really a money-saver, either, unless you're a trained mechanic. You'll end up with a code that tells you a symptom. What usually happens next is that the Lansing area parts store sells you something that directly relates to the symptom. It may or may not fix the problem. It's actually cheaper to just go to AutoSurgeonInc and get things fixed right the first time.

Remember, a fever can indicate a sinus infection or appendicitis. An antibiotic may be okay for that sinus infection, but it likely won't help your appendicitis. Is it really wise to wait around to see if the antibiotic helps when you might have appendicitis?

Part of good vehicle care is knowing where you can get a problem fixed — and fixed right. Preventive maintenance goes a long way to keeping you out of the repair shop, but eventually, we will all have a problem that needs fixing. Let's do it right the first time at AutoSurgeonInc.

Lansing Car Owners Ask: Why Do I Need to Change My Serpentine Belt?

Posted September 12, 2016 10:28 AM

Any Lansing driver who understands preventive maintenance knows that “if it ain't broke, don't fix it” is bad auto advice. Replacing a part before it breaks is much less costly for Lansing residents than repairing the engine damage that comes after a part breaks or fails. A good example of this is the serpentine belt.

The serpentine belt gets its name because of its circuitous path around the engine. The serpentine belt is driven by the engine and powers a number of systems, as follows:

1. The serpentine belt spins the compressor that generates the cool air for the air conditioning system.
2. The serpentine belt powers the alternator. The alternator generates electricity for use in the vehicle's electrical systems and to charge the battery. Without the alternator, the battery wouldn't last more than a few miles.
3. In many Lansing residents' vehicles, the serpentine belt runs the pumps for both the power steering and the power brakes. In other vehicles, the power steering pump may be electric and the power brakes may use a vacuum boost.
4. On many vehicles, the serpentine belt powers the water pump. The water pump keeps coolant circulating through to maintain appropriate operating temperatures. In some Michigan vehicles, a timing belt runs the water pump.

When a serpentine belt fails, all of these systems fail as well, which can lead to engine impact.

Replacing parts before they break saves money for Lansing residents by preventing more repairs and the frustration of having your vehicle in the shop for an extended period of time. If you're looking for an adage to apply to good car care, you might remember the old story of how “for want of a nail, the kingdom was lost.”

My son limped his vehicle into Auto Surgeon's parking lot . The vehicle is on its last leg and we just needed to get it up and running for a few more weeks til my son graduates. The proper repairs were out of the budget so Bill came up with a solution that made sense for this vehicle, Bill didn't have to adapt for us but he did, and the price was more than fair. Don't hesitate to call Auto Surgeon for any repair.quotes-image
