I'm going to give it a go. Anything I should know before taking a socket wrench to my car? I've got the new thermostat, I was told it's at the engine side of the upper hose on my radiator. I'm quite sure I've located it. Seems to just have a clip holding the hose on. I plan to take off the clip, pull off the hose (the engine will be cool), see how the old one was in, put the new in the same way, and re-attach the hose. Oh yeah, I bought a gasket too and I'm figuring I'll see where that goes once I take the hose off. Am I in trouble???? Or is it as simple as I just made it sound. The car is an 89 honda civic hatchback that overheats in traffic.
