Also, has anyone had to deal with getting stop leak out of the coolant system? I'm wondering if a flush will get it out.

And no, I'm not the stupid dickhead that put it in....

I'm wondering the same thing. I can see my thermostat open at around 195 (I have my sender in the upper rad. hose...I know NOT the best place and I have plans to move it, but I can see when my thermostat opens...). During light cruising on a hot day it might max out at 205 or 210. During hard driving it might go up to 220. I don't know what t-stat I have, maybe it's a good excuse to replace it now anyway to make sure.

Around 118*C it will start heading north on the stock temp gauge in a hurry, 220 might be a tad warm, but it shouldn't kill your engine, if Toyota's engineering department set the gauge to read 'normal' from ~80*C-118*C...

Crap, that's what I thought. Jay is going to try using some off the shelf flush, so I hope that it hasn't set in fully. Thanks Ian

I believe 176*-210*F is considered normal range, any hotter than that and the ecu starts making adjustments to get the temp down.

That's what I was afraid of. It sounds like there are some cores clogged....in a brand new Koyo Radiator. Nice...... Not happy
