I'm having a fit.....my 94tt mkiv has just boiled over like crazy! I was on the Highway for just a few miles at about 65-70mph. About 1/2 mile before exiting I sped to maybe 85ish until i reached the exit ramp. I came to a stop at the bottom of exit ramp and noticed my temp gauge at the red mark (stock gauge). It was definitely hot and boiling over, so I limped to the gas station about several yards away and killed it.
I'm pretty sure (until morning) that the only place I was loosing water was through the overflow. The undercarriage beneath the engine seemed to be completely dry while the bumper/grille area was soaked with water. I popped the cap and it smoked for some time as I was running pump water into the cap to cycle out the hot shit. I did this untul it idled with normal temps and no more smoking.....then limped it to the next station before nearly boiling again......repeated the cool-down steps with more fresh water. Then drove to my G/F's house about another 1/2 mile. I would drive to cruising speed and then kill it...then coast, then restart for another block or so, then kill and coast again. I got the car to her place without getting excessively hot and then cooled it back to normal once again as I cooled it down with more fresh water etc. It's parked for the night with cool temps now.
When I bought the car at 30k miles (52 now / 3.5yrs later) I replaced the thermostat, rad. hoses (upper and lower), rad. cap (i think). The motor is all stock except for 16lbs from manual boost controller, and DP. Never gave me trouble ever before with heat.
***During the drama, it was clear that the thermostat was opening and closing, the pump was pumping and spewing the hot water out as I filled with fresh, the hoses don't seem to be cut, and the cap is creating good pressure......all seems fine at this point - WTF???.....so I'm lost as to what it could be, except for the fact that maybe I cracked something during the pull on the highway, but that little highway pull seems so insignificant to my circumstances/mileage and the fact that it's a freakin supra engine!
I will pull the oil plug when I can and look for a milkshake, but c'mon!!!!!..........52k miles on a nearly stock, easy-driving supra????
Sorry for the long read.....any thoughts before I slit my wrists!!!!!????
Thank you,
Sean
