Author Topic: Cooling Prob! (Read 9478 times)

Well my thermostat went out wed, so I got home and ordered the new one. I decided to get the 75 degree one instead of the stock 88 one. Well it comes in today right before I go to work.

Problem is I need to go to charlotte in the morning. So when I got off work tonight I put the new thermostat in. No problems till I start to refill the coolant. Coolant starts leaking out. But its not leaking from a good place (like any is good :rolleyes: ). I look were its coming out and it looks like a hose clamp came off. NOT!! there is a plastic rail thingy and it broke off where the hose clamps on. and it broke off to short to keep using. I have a yard in gboro but I don't know if they have any M42's. BAHHHHHH!!!!! Not to mention I need to be in 10 places this weekend. When it rains it poors.

Look to where the screwdriver is pointing. What is that plastic rail thingy and where can I get it fast if my yard doesn't have one. I only have one car!!!

how bad of an idea would it be to try to cap it off somehow and drive bout 2 hrs each way? I don't even know what I would use to cap it.

arrrrggg crap always happens at the worst times

well off to the stealership, they say they have one. I'll post the part # when I get back. Apparently its a pretty common prob since the plasic is on the side of the engine black and get really hot, not to mention its 15yrs old.

I replaced mine the last time I had the Manifold off. I think I'll delete it next time around.

Ok guys I really could use some help. I replaced the thermostat and I'm still running REALLY hot. Like the car is past pegging out. Now I'm not driving it around since it started doing this but I have to test it like after I replaced the tstat. I replaced that plastic thing and the tstat w/ a new housing gasket. Its not my radiator and I don't think its my water pump. Is there a way to chech the pump?

Not to mention I think something may be fried, I guess the rebuild is coming before the turbo. Its making some funny sounds now. The only prob is right now I don't have the time nor have I set the funds aside to build it the way I want before the turbo. I was planning on doing that later down the road.

Odd thing is I don't feel like I've lost any power or anything. The car still drives and feels exactly the same minus the running REALLY hot and now weird noises from the engine

If anyone has a good M42 around NC that will let it go cheap you would be my hero.

Bleed it with the little bleed screw on the top of the tank. #8 in the realoem drawing of the radiator.
Use a contact thermometer or one like the A/C repair folks use to rule out a bad guage or sending unit. I spent a day once chasing a bad guage by changing t-stats and water pump. Water pumps usually get loose in the bearing and leak or wobble if they're bad. Check the temp all over the place - radiator, hoses, cylinder head, all the little hoses, wherever. With the cap off the overflow tank there's usually a small stream of coolant at the top flowing into the overflow tank. Also open the heater core with the temp switch on the dash. Air sometimes gets trapped in the hoses, etc.

the radiator just gets a little warm, the VC and IM are the things that are getting REALLY hot. I don't know and exact temp but pretty freakin hot. I've also changed the coolant. I didn't say that before.

well its been past red, and the check engine light came on. But it wasn't on for long at all. I shut it down. the check engine light was off when I restarted it later. There's not too much I can do b/c its my only car and I need to get to work and stuff. This is just really frustrating. Things like this happen at the worst times

Bleeding it could be the problem. If there is an air pocket in the head around the temp sensors it could be part of it. Other than that, your problem is pretty bizzare. Have you pulled out the water pump to see what the impeller looks like? If it is one of the plastic ones it may have disintegrated as it has been known to happen. Good luck!

^^thanks man, I am looking around for s50 pistons now and checking everything out incase I need to rebuild it soon. I guess I have to sell the t3 and get the holset now. So much for planning ahead. I guess its best this way in the long run. Who knows.

I changed the coolant after it started overheating. I guess the pump come out tommorro.

well its been past red

Congrats. You just f'd something up.

PEOPLE, DO NOT LET YOUR MOTOR OVERHEAT!

I would shut it down if it got past 3/4 on the guage.

Its not the end of the world... when my alt. and water pump belt broke a year or so ago mine overheated to the point where the light came on. Ive driven it 30k miles since then and it couldnt be running better.
