likely spots for coolant leaking?
Posted 15 August 2006 - 11:06 AM
also any handy tips on replacing an ea82 clutch would be apreciated. god i wish i had a hoist.

1. Did you replace the rubber o-ring on the pipe that connects the water pump to the lower radiator hose? If you need to replace it, lube the o-ring with a little grease or oil to get it to slip into the water pump easier.
2. There are two little hoses on the intake manifold, one on each side, that transfers coolant from one side of the motor to the other. They may develop a leak. Replace these hoses with OEM ones from the dealer, or gas-line hose.

i suppose that intake man. gasket should be replaced now, instead of just tighten and go. could the coolant be getting into the oil sys thru that spot? or only into the combustion chamber...
hopefully somebody will check in on this thread. I'm trying to keep as few running as possible.

I'm assuming you have checked and flushed out your radiator?
You very well may have a bad head gasket. It's actually pretty common on the EA82 if it's been overheated. Most of the ones I've pulled out the gasket disintegrated in a small spot where the coolant passage runs about 1/4" from the combustion chamber. Last one I pulled apart it was on cylinder #4 near the rear bottom corner of the gasket. Compression test showed 150 on each cylinder.... the leak is small. Small enough to not make a white cloud, and small enough pass a simple compression test. But it will pressureize the cooling system with combustion gasses, and cause overheating under load.
Frankly, just diving in and doing the HG's and manifold gaskets will probably solve all your problems.

the rad was new from previous owner, and feels uniformly warm when i run my hand up and down it.
so that'll be water pump, then clutch and front cv's, now head gaskets and man. gaskets, all in three weeks.

i was having trouble with my car heating up on hill climbs. itwas losing coolant before, but i fixed that with a new water pump and two new little hoses on top of the engine. i knew that my intake man gaskets were gone, but i was suspecting that my hg's were gone too. banking on it actually. I was prepped to do the hg's, but after i got the intake man off i got scared, and just replaced them and the the tstat, then put it all back together. i test drove it up my fav five mile hill, and it heated up again. but i had my grille off, and checked the rad at the top of the hill. (third check). i finally realised , feeling the rad from the front, that t he bottom 1/4 of the rad wasnt hot. so i threw in a new rad today and did the same test drive. no heat up. drove the sheeit out of it, 4500 rpm climbing much of the time. soooo... im still not sure that my hg's are ok, but the new rad has definitely bought me some more time.
i hate sube stock hose clamps. im replacing them all as i go with standard worm gear style clamps.

Me, i know ive blown two main radiator hoses, an unidentified seal with the water pump (never "found" a problem with it but it was leaking out of sight BAD) and now one heater hose, and ive already used the "replace the radiator" band-aid.. so I'm pretty sure. I just hope my heads are OK.
