I have a 2000 Explorer and I have to change the thermostat. Is it hard to do? I don't know to much about cars, but I wanted to try to change it myself. Thanks.

 

Very easy, go for it! Here this may help:

I replaced it, was pretty easy just takes time. Buy the parts at autozone, the o ring is about 23 bucks at the dealer, he couldnt tell me the price with a straight face. mine went out about 70k and again at about 140k
