Last Coolant Question

[dvmotorsports]

As we have already established I am not to familiar with "Ze German" cars.

I replaced the thermostat, o-ring, and gasket today.

It's still overheating. I ran some dye through the system and have a general idea where the other leak is coming from. The furthest I could trace it without pulling the car apart was to the AC Compresor. Maybe it is leaking from there.

Has anyone else experienced this problem? What is the proper course of action if it is the compressor (seals, full replacement)?

You can replace the seals... just like anything else... it bolts up with a gasket type fitment... you can get this from the dealer... or an online parts dept. and replace as needed.

Can it be agreed upon that the AC is the only thing mounted in that area on an M42 that would leak coolant? Or is there something I'm not seeing?

I would honestly have to do some research to where the coolant travels around the A/C unit... I'm not sure it exactly goes around there or not...

How much fluid are you losing?... Big, small... puddle... ?

Get her hot... and look under the car while she is running... you might have to remove the under paneling.. in the front... but its worth a look... and see where it is coming from... get a mirror... search around.. thats the best way I've come to find leaks...

Good Luck,

The AC system should not be responsible for a coolant leak. It contains freon (or some variant thereof) and not antifreeze. I'm not positive about your particular make of BMW, but is highly unusual for any AC mounting bolts etc to penetrate the block into the coolant system.

That is what I was thinking. But I just can't figure out where it is coming from. I guess I am going to have to do the dye test.
