High speeds for 15min or longer, temp gets high

[rob87]

I'm not running the AC, that is another problem I have to fix but that's for another day..lol

[wstanek]

In my 87 N/A manual it shows that the regular operating temp is anywhere for 1/4 to almost red lines on stock temp gauge. so from the sounds of it doesn't look as though its over heating~

[batmmannn]

Well that can't be right cause my temp guage never reached the red and my radiator was boiling so I don't think that estimate could possibly be correct as far near the red being normal.

[wstanek]

well a couple b4 the red line in the ORIGINAL manual for 87 supra N/A Standard says almost b4 red is not over heating

[batmmannn]

Well then they must be cooking eggs, cause at that temp my car was boiling so bad it was leaving and overflowing the overflow bottle.

lol Toyota derp!

but it will tell you that is NOT normal operational temp, if it goes over half way you have a problem somewhere...

did you replace your thermostat
does your turbo have the stock heat insulator? or heat shield of some sort?
make sure your getting enough antifreeze and you could try adding a coolant additive.

CHECK ERROR CODES!!!!!!! ALWAYS CHECK ERROR CODES!!!!!!!

if the ac doesnt work why keep it?? really it just slows us down and gets in the way under the hood, the system weighs a fair bit i dropped mine

it has a new thermostat, just put it in about three weeks ago. I put it in then because I noticed the thermostat housing bolt was missing/broken, so I replaced it since I was working on that anyways. I'll check the codes here in a little bit. I have no warning lights that indicate any issues, just that the temp gets high at constant high speed over 20 minutes or so.

Iuno im prolly just getting tired long day at work... haha... no but seriously long day.

[rob87]

just checked the error codes and I have no errors.
