It's seems so basic, but thermostats are a very important part of your cooling system. In fact, they are the gatekeepers of the cooling system. We don't think much about them until something goes wrong. In this video, we talk about the basics of thermostat operation and do some testing. I also take the opportunity to do a head to head comparison between an OE thermostat and an aftermarket one. You might be surprised at the results, I was.

I will say this. If you have a cooling system issue, the first thing to check for is air in the system. In fact, I cover the basic steps in diagnosing a cooling system in this article.
