Thread: Water temp question

Yes, I would say over 220°F is pushing it. And really you probably don't want to get that high anyway. Above 212°F is not the end of the world though. The system is under pressure so the boiling point should be around 230°F.
However, in general I'd wonder when your fans are set to come on. If temps still rise with the fans on, you're in serious trouble. If the temps drop once they come on you're in good shape.

what did the ecu say the water temp was? I have noticed there is a difference in what the head temp says the water temp is and a aftermarket gauge. the sender for the gauge gets heat soaked causing it to read high. especially when sitting still.

Where did you put the temp sender at?

Mods in sig, my se-r has a GA radiator and AC. Today at 90*F i saw 190-200*F coolant temp driving around. In stop and go traffic it remains around 200-205*F, driving over 65mph the temp goes to 210-217*F with AC on.

B13, Orlando fl, ve-t, no AC, Honda two row rad: street driving 180-188. At the track and beating the hell out of it in the heat 190-197ish. I have yet to see it log over 200.

I have not messed with the ecu datalogging yet..I guess its time to get going with that
I was wondering about heatsoak sitting still since the sender is in the water neck(its sort of close to the turbo manifold)
So it would make sense that sitting still would cause heatsoak.

Hmm

I put mine in the upper rad hose with the "SickSpeed" eBay adapter

I have mine mounted in a cs water neck plate so mine sits in about the same area. I know my gauge reads higher compared to the head temp sensor from checking my laptop.

My temps drop to 165 at 60-70 degrees while cruising boosting not more then 200 ..new thermostat as well ..I need a new one to open later ..this is with a mishimoto rad.
