JamieB Member 58 Member For: 11y 6m 15d Posted 10/10/16 02:57 AM Share Posted 10/10/16 02:57 AM HeyWondering what everybody's opinion is on cooler thermostats when modifying xr6turbos. My tuner has recomended I fit a cooler one as my coolant temp goes up to 104 after 1 hard run. I have mixed feelings about cooler thermostats, I think its a mask and once it's open of its going to get hot it will... another company told me that they tried the trident 81° and they got inconsistent temperature so changed back to factory.The other option is trident have standard temp thermostats 91° but they flow 30% more, but I have heard mixed things about these too, that it may not cool as well because the coolant moves through the radiator too fast to cool down..Cheers Link to comment Share on other sites More sharing options...

I reckon it kinda helps to protect the auto transmission and I have no issue with the heater working well in my car (something I was scared would be the case as I love the heater). Mine doesn't get much hotter than the 1/4 mark, it'll go between the 1/4 and half mark when giving it a thrashing. I believe the tuner will play with the fan settings when doing the cooler thermostat. Link to comment Share on other sites More sharing options...
JamieB Member 58 Member For: 11y 6m 15d Posted 10/10/16 07:35 AM Author Share Posted 10/10/16 07:35 AM I do have a trans cooler and not worried about heater especially this time of year it is quite hot where I live.. more worried about the time it takes to come up to temperature.. I also don't belive the standard gauge is a very accurate tool to measure coolant temperature, there is a very wide window between 1/4 and 1/2 way.. it is sort of idiot proof.. I have an ultra gauge in my obd port but for some reason always displays coolant temp as -40.... Link to comment Share on other sites More sharing options...

I hear the oil takes longer to heat up than the coolant and your thoughts on cooler thermostats are not incorrect, just for modded t's it's good.

Or playing with the thermofan cycle Temps Link to comment Share on other sites More sharing options...
