Some of us are what we’d call “handy,” which means that we are good at fixing things and not having to seek out the help of professionals. However, when it comes to cars, no matter how handy you are there are still some repairs that you should always leave to the pros. Sure, it’s an expense, but I for one would rather pay and know that the job is being done right than leave it up to chance and risk a seized engine.

First of all, don’t touch the transmission. Don’t even change the fluid. If you mess up the transmission you’re in for a much more expensive repair than you had on your hands before you decided to try and repair it.

Windshields are another thing that you just need to bring to glass professionals. Even those store bought kits that say they fix cracks are lying to you. Just get a pro in there and you’ll be set.

Anything to do with wiring has been off-limits for me for a while, but I need to remind us all that trying to tinker with anything in the car that has a lot of delicate electronics is a bad idea. So no putting in a new sound system on your own! Do you know how bad electrical fires are? Stay away!

Don’t think about touching the fuel pump, either. This is not only a very precise part, but it requires precise installation and even the smallest mixup can total your engine from the inside out.

The final thing on my list is engine diagnostics. This should be a no-brainer. The little code reader you can get that turns off the check engine light doesn’t actually fix anything, so why waste money that you could spend on getting what’s making the light come on repaired?
