Hello,

I have an issue with the coolant on my 1990 760 GLE. Just bought the car. It runs great, but the coolant is disappearing. The previous owner did tell me that this was the case and that he regularly (once every couple months) had to refill the coolant. I did not run into any engine issue. However, just a few days ago I added almost a whole bottle of coolant and filled up the expansion tank just below the max mark. I checked it again tonight and the coolant was totally gone from the expansion tank. It is *not* leaking down to the floor of my garage at night and I just can't tell where the liquid is going. I tried to fill around that bigger hose that goes from the expansion tank to the radiator and the underside of it felt cold and wet. Since the whole engine is very dirty; I am not sure if what I see or feel in there is oil or just coolant that has been leaking over dirt. There is some liquid on the large metal bars at the bottom directly below the hose.

Sooo....my totally inexperienced guess is that the hose is messed up and when the pressure is high (the car is running) the coolant leaks through it...

I also have what appears to be an oil leak dripping from that large bolt under what I think is the oil pan (I can see it pretty clearly just kneeling down at the front of the car). At least I hope the leak comes from there, not from higher up.

Any way, I'd say the oil leak is less scary because at least I can see it, which is not the case for the coolant.

The thing is, my local Volvo mechanic doesn't want to touch the car because it does not have a Volvo engine, and I do not know of another trustworthy (and yet not too expensive) place to have this checked out right now.

Any hint of what to look for? The first thing I did is make sure I have coolant and oil in the trunk. Second thing is I wiped out the wet stuff under the hose and I plan to check it out again for wetness after coming back from work tomorrow...I think I'd be happy if only a hose needs to be changed :)

David.
