The normal operating temprature for any engine should be 70-90 degrees Celcius, from what i can remember… 150 is waaaaaay to much. EDIT: this is for coolant temp. Oil temp will be a bit higher, like 110 or something i believe. ---

My SR w/ Koyo rad + 16" e-fan (and a large T3 turbo) operates between 80C (175F) to 83C (180F) daily driving/highway driving. Averages about ~80C. Track I’ll pull into pits after it hits 93C (200F) to 100C (215F) Pics here: [www.son240sx.org/forums/showthread.php?t=44838](http://www.son240sx.org/forums/showthread.php?t=44838) ---

Note: The temps I gave above are “Post-rad” (after it’s cooled). Pre-rad is usually 10-15F higher (eg. ECU sees 180F, where as my autometer gauge which is mounted after rad, sees ~190F) As long as your post-rad temps are in the 180F range it’s fine. ---

With AC your motor is obviously working a little harder. I wouldn’t be too worried about 210F but you might want to consider flushing your coolant system and ensuring it has no air pockets.
