First let me say this: This Bonneville forum is the Sh*t!! all I think about is upgrading my 92 SSEi. With that being said...i want to upgrade but i don't have a clue as to how. I'm going to purchase the 180 T-stat, but how do you instal it?? The Techinfo doesn't tell how to.

I'm trying to remember what I did.

Maybe others can help me out.

What you will need is the thermostat and a new gasket for it.

You make sure the engine is cool, and then take off the cover where the hose connects to the engine. I think there are two bolts.

You remove the old thermostat and gasket, and then remove any excess crap that the old gasket left. Once that is all cleaned, you can put in the new one, along with sealing down the gasket, and then bolting everything back on.

Am I missing anything?

the thermostat has its own o-ring doesnt it? as well as the water outlet housing gasket? i havent installed mine yet but from what ive gathered thats what there is to it right? also does the t-stat have to be turned a certain way or somethin or does it not matter?

I don't know about the O-ring, but I believe postion does matter.

im not sure either. can we get a guru up in here?

I just worked on my thermostat today, all you need is the gasket and a rubber seal that goes around the thermostat unbolt it watch the coolant poor out clean the old gasket off put new 180 thermostat on with 2 dollar rubber seal around it trust me you should replace it my origenal one was hard as a rock then after that gasket then bolt everything back on, i didnt get to find out if it runs better cuz one of my bolts broke of in the engine block anybody can help me out there, im welder and im to protective of my bonneville to use any welding stuff on it so anybody have any recomendations for it somebody said to use a reverse drill bit.
