Message	If you have a stock ecu then 178f is where you want your water temp to be. However you have a need to run a lower temp its easily corrected for in the ecu. The main question is what water temp makes the motor most efficient while maintaining reliability. To my knowledge no one has really tested that. Also keep in mind what truly matters is oil temp. If you log the factory oil temp you will be shocked how high it runs. Btw there are cars that run 250 f oil temps and 230 f water temps routinely. The z on the other hand is close to meltdown at those temps. Harry Formerly yellowzxtt

I had a UR, HOWE - PiotrC70 17:49:42 11/18/11 ditto. (n/m) - Halo TTZ 19:10:00 11/18/11 2nd (n/m) - HighPsi (NorCal) 01:54:49 11/20/11 what is the optimum operating temperature? (n/m) - fuzzymonkey 18:14:41 11/18/11 IDK but under normal city driving in summer - Gennosuke 19:29:10 11/18/11 Hmm... - madscientist222 18:24:26 11/18/11 so then the stock pulleys would make the "water circulate - Halo TTZ 19:12:49 11/18/11 Did you say 62-70 degrees? Don't make no sense - RevTech 19:31:15 11/18/11 Probably means centigrade (n/m) - dogpile 19:35:53 11/18/11 What is centigrade? (n/m) - new2boost 19:50:23 11/18/11 Celsuis.

(n/m) - new2boost 21:35:04 11/18/11 should be between 190-210 degrees (n/m) - LiftedCracker 21:41:04 11/18/11 70C is 158F. which is too cold - dogpile 00:09:54 11/19/11 From the US...North Carolina I believe.
