Thermostat on 02 ss?
After doing more research and advice from you guys, i've learned that i need a thermostat and not the coolant temp sensor i changed last week. I had it flushed and added new coolant last week along with the sensor change. I've read on here today to definately go with the al delco t stat. my question now is, does anyone have directions on how to replace it? and do i have to drain the coolant again?
also whats better the 180 or 195 stat? i plan to get the stat today and if its pretty easy i wanna try to change it myself. to save a lil money. |
Depends on your weather and what your doing to your car.
If you are doing engine mods and putting a smaller pulley on the supercharger and think you might run warm use a 180. If you want heat to come out of your air-vents in the winter use the 195. If you live in Texas or Arizona or somewhere hot all the time use the 180. |
As far as changing the Tstat, just follow the upper radiator hose. It will lead you straight to the T-Stat housing. It's two bolts (I think the one has stud coming through it and a nut on top holding a small bracket, so you may need a deep well socket). To my knowledge, the ONLY gasket required is more like a rubber ring that goes around the t-stat.
Easy change, should be a 5 minute task. |
You don't even need to drain the coolant on the 3800 when you change your T stat. Its right side up on the top of the engine. Its on the drivers side of the engine bay. Like Maniac said, follow the upper radiator hose, and it will take you right to it. To bolts and you're good.

Thanks alot, no need in paying $40-$50 for this to get done. i'm gonna go with the 195, i'm in md and definately need heat in the winter. i'm gonna give this a shot my self this evening. one last question can i take this housing off after driving the car or does it have to sit for a while? don't want coolant everywhere.
thanks again. |

thanks again. Not to mention, it's HOT! Warm/Hot, you're coolant system may still be holding pressure and you're asking for a mess of coolant everywhere (including hot coolant on you) as you open up the T-stat housing. Play it safe, let the car cool down (if you get it on your way home from work, get home, pop the hood, go in have dinner, I would say give it at least 2 hours before you check it). |
NEVER change a thermostat while the engine is warm. It WILL be under pressure. Just read the radiator cap. If you wouldn't open the cap while the engine is warm, you absolutely would not go unbolting the thermostat housing while it's warm. If it were me, I would wait until there was a day that I could just wake up and go to work on it. Make sure that you have the seal and gasket for it and you're all set to go.
It's an easy EASY job to do on the 3800's. |
Check out Youtube here is a nice video http://www.youtube.com/watch?v=Tuo28XWAMoE
only thing I would do different than this guy for sure is put the oil filler neck and cap back on first thing after removing engine cover. I never put the engine cover back on after changing mine earlier this year. and yes, get the Delco therm from the dealer, and wait for engine to cool. |

I'd go with the 180 if I were you. I've got the 180*t-stat and have more then enough heat in winter, even when its 10 below 0.
