Look at this smug motherfucker.

In case you didn't know, this is an automotive thermostat.

It sits in your engine and determines if your engine needs coolant (or radiator fluid, whatever you wanna call it).

This particular little bastard is a 195º GM thermostat, circa 1994. It comes out of a 4.3L Vortec 4300 V6 engine. The problem with this little bastard is, it's rusted.

Now, this doesn't happen.


Well, it so happens that, the original anti-freeze that was being run from the factory was Dex-Cool™, probably known to most people as the "Orange shit that shouldn't be in there in the first place, but GM seems to think it's the best goddamn thing since sliced bread, even though they're wrong"

About 5 or 6 years ago, my truck was switched over to Ethylene-Glycol anti-freeze, or "The green shit that works right and every other company on earth has used for years and continues to use". Now, Dex-Cool™ is known for screwing up cars. We switched when GM finally admitted "Okay, it kinda sucks".

Well, that was late enough in the game to have started gunking up the thermostat, causing it to rust. It didn't rust through, but it was beginning to rust.

Now, let's go back to Monday, as I'm pulling up to my house. My car started getting hot, so I shut it off and coasted into my parking spot. Tuesday comes, figured it was a bad fan belt, which it wasn't. Today, we picked up the new thermostat, and went to replace it.

That's where that smug little motherfucker comes in.

He had rusted shut.

No matter how hot that damn engine got, he wouldn't open, because rust had caused him to permanently lock up. This little bastard almost killed my truck.

The new part was $11, and it took five minutes to replace.

I, nor anyone I showed it to, has ever seen a thermostat so fucked up before.

The smug little bastard.
