Anyone know if GM or someone else offers lower thermostats for our 2.4s? I was thinking 160 degree would be great.

 

i can see where the thermo is its easy to get to just 2 or 3 bolts or nuts. and you could get one at autozone different temps. but then your heater in winter will be colder for lower temp thermo. and if you go with a lower temp thermo its open more and more so your having a constant flow. at 160 degrees i dont know i would say no just keep the stock thermo any changes like that would probly not make a diff.

No one carries them that I found, nothing at any including Autozone etc. Cooler engine temps allow more timing and hence more power.

 

With your tune you can set it for you fans to come on early, that helps keep the temps down. But if I am not mistaken are stock thermostat is 190* is it not?

 

well its either 190 or 195 cuz my car runs 190 all the time and my fan is on all the time. but then its set for lower temps i guess. but im workin on bigger issues right now.

Well that's my point. mine runs 185-190 all the time. Fans kick on at 190. I don't think you can adjust the fans to come on any lower than 180-190 anyways. Therefore the 160 thermostat is a mechanical alternative to having the fans run all the time. More coolant flow is why it lowers temps. And the heater in my car is OUTRAGEOUSLY hot in the winter. I doubt it will lose much effectiveness with the 160 thermostat.

 

^^ agreed.
I live in alberta, and in the dead of winter the most ive ever needed is the #2 fan setting.
#1 is usually plenty
and thats when its seriously ****** cold outside.

 

This was a biggie on the 3800's for my bonneville. Helped us keep from cracking plastic intake

 

I think their was a thread some where a while back showing how to wire up a switch to turn the fan on and off rather then having it turn on at a certain temp. Might be something to look at rather then the thermo.

 

A lower temp thermo if you can actually find one will set a CEL and is actually a semi common problem we have seen. The thermos get stuck open and DTC P0128 Engine Coolant Temperature (ECT) Below Thermostat Regulating Temperature sets
Conditions for Setting the DTC as per General Motors

The ECM detects that:
• The calibrated amount of engine run time has been met
• The calibrated amount of engine air flow has been met
• The calibrated vehicle speed and distance have been met.
• The calibrated ECT of 80°C (176°F) has not been met

because you have a 2.4 you should be able to tune it

 

Well how low a temp can we tune out the CEL with HP tuners?

 

I'm having this problem with mine... seems to have happend after i put on an intake.. Maybe its not reading engine airflow correctly? Anyone know the part number for the thermostat on the 2.4? I have had my ecm and coolant temp sensor changed with no success.. i just keep reseting the code and the car is back to normal...

 

anyone?

 

Try putting your stock air intake back together. If its still throwing the code take it to the dealer for a warranty repair. If it stops, sell the aftermarket intake or get it tuned

 

I've never really understood why someone would want a lower degree thermo, It's only going to cause problems in the future, i.e if you don't get up to normal operating temp it will stay in closed loop and will stay rich. Also it will make problems with the oil sludging. Maybe I'm missing something?

 

Lower temps reduces performance. Heat inside the combustion chamber allows more fuel to burn next stroke.

 

Are you being serious...????

 

I have a 180* thermostat but w/hp tuners you cant tune below 192*

 

lol this makes me feel a lil better about my cars operating temps its always runnin like 190 -210 which is normally a lil Hot on say every car ive owned up to thus far.
