Normal coolant operating temperature

[juiced305diesel]

Hey guys i been trying to find out all day what the normal operating tempature of an Sr20det is. I have been reading alot of the older threads but there is no sure answers. I have a koyo and mishimoto fans and shroud. My normal temps driving around are in the 180s after doging the car its gotten to 205 then starts dropping off again. My oil temp on the highway is between 150 to 180 depending on traffic.

Sounds somewhat normal. On mine, if temps outside are 95+ my coolant temps like to stay at 180*F crusing. 85ish temps outside coolant is at like 172*F. Only time my car sees 205ish is on the track. Oil temps I dont know.

check the thermostat, it should have a little number..thats the temp. it starts to open up

I know what temp the thermostat opens up at. What im looking for is what temp your cars cruise around at. I would also like to know what temps your getting after some WOT pulls.

well thats normal operating temperature, your original question...

now you can find the answer to your second here Normal operating temperature - SR20 Community Forum - The Dash (http://www.sr20-forum.com/general-sr20/10040-normal-operating-temperature.html)

Mine fluctuates from 180-190, but my fan kicks on at 190 so it cools it down to 180 and stays between 185ish. at stops if i drive hard or its hot the fan kicks in again. i've seen it go up to 200 when im boosting hard for a long time on the highway, but it rapidly goes down as i let off the gas. hope that helps.


i do have koyo Nflow radiator, spal fans, arc oil cooler, arc radiator cooling panel. i dont know if that makes a difference.

Cruising with the AC, my car sits at around 80 (176 ish), creeps up a bit higher if stuck in stop and go traffic. Track wise, 90-95 (193-203 ish), if it hits 100, im parking it to chill...

Oil temp sits at around 70-80, highest i've seen it on the track is almost 100 when my water temp hit 105 on the track with my old Rad and E-fans.

Rule of thumb on Oil temp...Dont ever let it get close or over 120 (248 ish). Oil starts breaking down and cooking up there and looses its lubricating capability.
