Over heating.

DavidLeClair584 · 06-04-2007, 06:34 PM

Hello, everyone. I purchased a 1989 Toyota Supra 7M-GTE (turbo, manual) a few months ago. And, now that the snow is gone, I'm out driving it. However, as of last night, it's over heating. I've checked the coolant, and the cooler condenser fans... there isn’t a leaks, that I could see (no coolant on the ground) and all three fans work. Any ideas what it could be? I’m thinking it's a BHG… as there's white smoke coming from the exhaust... but I’m not sure...

Check the oil cap and oil dipstick and see if it is kinda milky. A sure fire way to test it, is to get a block test from your local automotive store.

The question is... if it does have a bhg do I want to get it fixed -.-'' I love driving my supra, but repairing it costs more than I bought it for.

Yea, thats usually what happens. If it has it, the time has come to decide if you want to fix it and keep it or try to sell it off.

It's a manual GTE, fix it. Its worth saving. Its really not that hard to fix a blown head gasket on these things.

If you see white smoke coming from the exhaust in summer temperatures, you have a problem. Oh wait I just saw you are from alaska, nevermind!

Lol. Well, today I made up my mind. I was driving my friends '93 civic, and then a '90 mazda, and decided I have to fix the Supra. IHateHacks, I saw the thread where you replaced your head gasket, mind sending me the parts list? I can't afford to have someone fix it, and I've managed to scrape together around $1,500 for the repair... Joy. Supras are just to fun to drive.

Yes you need special tools. I wanted to check my valve clearences and had to buy a special tool that pushes down on the shim bucket to take the shims out that didn't meet valve clearence specs. I also bought a micrometer that measured the thickness of the shim which I had to do to determine the replacement shim to get the clearences back to specs.
I couldn't get the tools here in Kuwait so I had to wait a few months till I went on vacation and got them from a store in California and they had to order them.
These engines aren't designed like american or german engines where you can adjust valve clearences easily.
The best thing to do is research the specific job in the TSRM and it will list any special tools that you will need.
Make sure you have everything you need before you start.

A few more questions today. I talked to the machine shops around town (Anchorage, Alaska) and none of them offer lapping. One of them said that after surfacing the head/block their machine leaves a really fine finish (he said he they used a C&C Machine... whatever that is?) Has anyone had any experiance installing a metal head gasket without lapping? What are your opinions on gasket kits? What brand is recommended?
