We all have our own specific skill sets, that’s for certain. My girlfriend can do all kinds of math in her head but can’t spell to save her life. I’m handy with the car, but I know I’m no good at things like plumbing. My girlfriend would also like to note that I seem to have a problem with washing the dishes and operating a vacuum cleaner. This is false and I just take care of those things when she’s not around.

Anyway, I wanted to share with y’all some of the things I’ve learned about at-home car repair over the years. As handy as you may be, and as in tune with your engine bay as you might think you are, there are some repairs that you really should just leave to the pros. I’ve found the shop techs at King Kia to really know their stuff, especially on my girl’s Sorento, and so I advise you to trust them when it comes to maintaining and repairing your car. These are the five things that above all I don’t think you should touch when you’re messing around under the hood. Let the pros handle these and you’ll have made a good choice.

1. Don’t touch the transmission. Don’t even change the fluid. If you make a mistake with 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.

2. Your windshield is another thing that you need to bring to glass professionals. Even those store bought kits that say they fix cracks, well. A professional will get the job done seamlessly, and the kit won’t provide satisfactory results. Just get a pro in there and you’ll be set.

3. Anything to do with wiring should be off-limits; 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!

4. 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.

5. Don’t try your hand at 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?
