A trusted mechanic can be a great resource for car repairs. “Trusted” is the key word there. As with any business, there are some mechanics who will put a quick buck ahead of what’s best for you, the customer. We’ve pretty much all dealt with someone like that at some point. The best way to protect yourself is by educating yourself so you can make more of your own decisions. Here are some things you should know, even if your mechanic doesn’t want you to.
1. They Don’t Have Automotive ESP
Mechanics don’t have psychic powers that tell them what’s wrong with your car. You can apply some of the same skills the pros use to diagnose your own problems. A good mechanic knows plenty of tests to find out what went wrong with your car, and although you may not reach the level of expertise of a pro mechanic, you can definitely learn some basic tests.
First, if your check engine light comes on, a mechanic will use a device called an OBD scanner to check for trouble codes that will point out the problem. You don’t have to take your car to a shop to get it scanned, though. Many parts stores will rent you a scanner, or you can buy one, sometimes for as low as $20. If you have an older car with frequent problems, an OBD scanner can be a good investment.
You can also learn how to test parts for wear and tear yourself. You can easily visually inspect brakes for wear and you can test suspension parts like hubs and struts by hand.
In some cases, your shop is just trying to figure out your problem by educated trial and error. They may try one part see if it works, and move on from there. Of course, with a little know-how about your car’s various parts and symptoms, you could do your own process of trial and error much cheaper, as our DJ Butler describes. No, it’s not the ideal way to fix your car, but sometimes it’s your least worst option. Read More
