Coolant leak seems to be behind a/c comp

Anyone else had this? I seem to recall another member complaining of this issue. I haven't had a chance to get it up (on the hoist, that is ) as yet, so can't pinpoint it exactly. Can it be the water pump? Car has 225,000 miles on it.

Sounds like the W/P. That's where my leak was. I let mine leak for almost a year before I finally changed it.

Nope mine is definitely lower...leaking a lot now. Might have to fix asap.

Did you change it yourself? If so how difficult? I'm going to dig out my FSM and check how to remove it.

Dont let that stuff sit, if you do it becomes really hard to remove it.

The thermostat and water hose is directly above the AC compressor. If it were leaking, coolant could run down the block and drop from behind the compressor.

If not that, then I'd check the water pump.

There is a weep hole for coolant leaking past the water pump o-rings on the side of the engine above the AC compressor. I had this back in September and changed the water pump. When I pulled the water pump out, it was perfectly fine, it's just the o-rings that lose their elasticity and take a set and eventually start to leak. The water pumps themselves are very well made and mine had no sign of bearing wear or impeller erosion (at 135k miles), so I could have saved $80 by just replacing the o-rings.

Getting the pump out involves releasing timing chain tension (I did that by removing the tensioner since I was replacing it at the same time I was replacing the pump) and using two M8 bolts as jack screws to jack the pump out. You should also change your oil after doing this since it is nearly impossible not to leak coolant into your oil sump when you pull the pump out. The Haynes manual does a good job explaining what to do.

Thanks for the info, I just checked my manual and your write is spot on. I also spoke to my mechanic ( a cousin ) and he recommended taking off the timing cover and also replacing the chain as we're there. This will also fix my oil leak in that area. Think of it as a Christmas gift to my Max . Also, will do the brakes and replace cv boots...much dinero.

Replacing the chain requires dropping the engine doesn't it. If your gonna do that you might as well drop in a newer engine. The chain itself is over $200 and you will need a new gasket.

I don't think I'll drop the engine, just remove the timing cover & work from the side of the engine.

On a 1995, I've heard of chain tensioners going bad but replacing the timing chain? Do you really think you need to? They are supposed to last the life of the car. I have the same problem but it's too damn cold to work on the car so I put in some Barr's Leak stopper and will tackle the water pump seals in the spring. Wasn't leaking too bad... about 8oz a week.
