Running Hot - Page 2

Benesesso · 03-02-2008, 01:22 AM

I've had this problem with both of my turbo Supras. I found a radiator shop that built me a couple of 3 row radiators. They helped, but the cars still run hot in the Phoenix summers. I changed the fan in the 1990 to a direct-drive stainless steel flex fan, and that helped, but it's a bit noisy.

In the summer, at ~110+ deg., both cars get up to ~220-230, on accurate gages, and the faster I drive the hotter they get. I run 50% antifreeze to keep the boiling point high. Both cars have good head gaskets.

I am convinced that Toyota screwed up and should have provided for a lot more airflow thru the rad.

Hey, my car finally spilled coolant everywhere when I drove it.....and I got the hydrocarbon test done. It was indeed the head gasket, though we are unsure of the severity of the problem.

My mechanic has said that this is a very costly repair, and he is urging me to get a whole new motor....what would you all recommend?

Please help me save my baby!!!!!
