Can anyone recomend a lower than stock temp thermostat. I have just done a greddy front mount also replaced stock rad. with a Koyo and the temps are fine now at the outside temp at 75 degrees, but with summer coming up I want to make sure it stays cool. Luckly it is not a daily driver but still want to keep the temps down

 

180 degree works great.

 

You need a larger capacity Radiator, not a lower temp thermostat.
You want to get rid of the excess heat, not circulate the hot coolant thru the system quicker.
Is this clear? Do I need to go on?
The stock 180' temp thermostat works fine.
Make sure both of your fans work, check them weekly or monthly.
If your fans don't work in stop & go traffic, it doesn't matter how "cold" your thermostat & how "big" you radiator.

 

I know it is working great now, but it is still the orginal stock. I was just wanting to know if there is another one that will work and keep it alittle cooler. thanks for any help

 

I did get a bigger radiator and both my fans work fine. I guess I will be fine. What is everyone elses temps in the summer in stop and go traffic

 

95c, my fans are on at 99c with PFC, fans will bring down to about 92C. this is 45 mins stop and go in 100F temps, I have stock 180 thermo' and stock radiator, and stock AST, and proud of it. cooling system works great!!!!

 

Im at 80C degrees C. Stock rad with a 180 Degrees F thermo and Fan mod.

 

sounds like you thermosensor is going bad!! 80C is to low for 180 thermostat. eve if fans on all the time. Also, it is not good to run egine that cold.
