180 degree thermostat

[johnnymossville]

I want to run a 180 degree stat in my 3400/3500 11.5:1 cr hybrid engine. The problem is the parts guys in this town are so anal that the can't match one up for me. Does anyone have a part number for me or know where I can get one? Help me please as I'm putting it together now.

pick one up from autozone or advanced. for a 3.1l

yep, find the propper one for a 3400 then compare that to the rest of them on the rack.. there will be a 180 the same size/shape.

uh, when i went in and got my 180* t-stat from autozone, i just walked in, said i needed a t-stat, and it had the option for a 180* one under the listing for the 3400.... took like 3 minutes.....

Why bother its a waste of money. Your going to loose mileage and performance. It is better to have your engine at or around 200*F so that any water content in the oil evaporates off. Plus fuel will burn better with a hotter engine. A dyno test will show power gains all the way to about 230*F but at that temp your leaving no safety margin for overheating so it is best to run between 200*F and 220*F. Every car manufacturer uses a 195* stat for a reason the only engines that run cooler ones are ones with tendencies to ruin heads. Like Isuzu 4 bangers and Toyatas. But that was only back in the day and none are like that today. Today you will find cars with even higher normal operating temps. Around the 210*F to 212*F area.

Buy a 195 thermostat, yes more economy and power past 200 degrees.

just because you have a 180F t-stat dosen't mean that's what temp the engine gets up to.. I have a 180 in mine and the car regularly gets up to 210F at the track.


It's just insurance to make sure you don't overheat.

If you have heating problems than no a thermostat wont keep the temp down. But that should not be the case in a street driven car. The thermostat should regulate the temperature.

If you running at 210 with a 180* stat than a 195* stat will do the same. The 180* stat will not give any extra insurance. Extra insurance would come in the form of a bigger rad or better fans/air flow through the rad.

Dave, what temp do you have your cooling fan turn on? My new laptop should be here thurs. and then I'll be able to install that 32 lb. injector bin file. I hope that it's really close so tuning won't take long.

[Superdave]

180F on and 175F off is the current one.. should be similar to the bin you are using.

Thanks Dave.
