Six Car Fixes You Shouldn’t Try on Your Own

  • The median age of cars on U.S. roads is now 11.6 years. If you’re hoping to get a decade or more out of your car, though, you must stay on top of repairs and regular maintenance. An otherwise small mechanical problem could turn into a bigger, more costly problem. With that said, there are some car fixes you shouldn’t try on your own. Stay safe as you do some of your regular repairs and remember to always ask a professional about the following:
The Most Crash-Proof Civilian Cars In Production

#1) Head Gasket Replacement

A blown or leaky head gasket is an all-too-common problem with older cars. It’s characterized by combustion gasses, coolant or oil leaking from the engine through the head gasket. While head gaskets themselves are relatively simple, accessing and installing them is painstakingly difficult and time consuming. It’s best to take your car to a mechanic for a head gasket replacement.


#2) Windshield Replacement

You also shouldn’t try to replace your car’s windshield. It’s hard enough to find a windshield that matches your make and model car, but it’s even harder installing it. You must trim it, add adhesive, install clips and more.


#3) Wiring Harness Repair

Consisting of a network of wires, transistors, and fuses, the wiring harness is the electrical hub of your car. Repairing or replacing it may sound simple enough, but unless you’ve done it before, it’s best to contact a professional mechanic.


#4) ECU Replacement

Replacing your car’s electronic control unit (ECU) is a task that should be left in the hands of a qualified mechanic. Also known as the engine control module, this computer is responsible for controlling the engine’s combustion process to achieve optimal performance. Failure to install it correctly could prevent your car from starting.


#5) Transmission Repair

Given the high cost of professional transmission repair, you may attempt a do-it-yourself repair if your transmission goes out. However, you’ll quickly discover this is a bad idea. Automotive transmissions are complex components consisting of dozens of gears, rods, and bearings.


#6) Airbag Replacement

In the wake of the Takata airbag recall, many drivers are looking to replace their airbags. Like the other fixes previously mentioned, though, this is a job for a mechanic. Messing around with an explosive airbag is downright dangerous, and it’s simply not worth the risk of bodily injury.


Even if you repair your car when problems arise, you will eventually need to retire it. If it’s damaged to the point where you can longer sell it to car buyers, take it to a junkyard. Most will gladly buy it for scrap, putting some extra cash in your pockets.
