Coolant question

P0WER · 08-28-2005, 08:34 AM

I just had a shop do a cooling system flush.
They assured me they know what they are doing as far as a Porsche goes (84 944).
They put in the orange stuff so I assume it's dex-cool.
Wether it was phosphate free, I don't know.
But I now have a leak.
And it's coming from behind the cover so it looks like it's probably a bad WP.
Could they have used the wrong stuff and messed it up?

Wonder what they flushed it with......Years ago I did that to an old Ford of mine. Followed directions I thought. Ended up replacing freeze plugs and the heater coil. Since that bad experience I never flush with anything other than water.

I switched to the orange stuff a number of years ago in my 944T. It leaked at hose fittings for a while but eventually quit. And I do have coolant in it.

Coolant liquid is notorius for finding leaks - more than water. Do you have the new style water pump or still the old pump?

No idea since I was jsut given this car.
But, I'll get it to a Porsche shop and have them fix it and check the belt, roller, etc....

do they work on foreign cars, any in the parking area.

shops, claiming to know what their doing has cost folks a bunch.

anti-freeze will leak where water won't.

don't know what year your ride is but i thought i had a bad cap on the old 84944, replaced it with one for a later model, which runs higher pressures and had a leak about where you describe.

it turns out the old cap was ok, put it back on, lower pressure cap and the leak went away.

The shop I am taking it too is one recommended on Clarks-Garage.com (Currey's) so I trust it.
Mine is an 84 944 N/A and it's leaking from behind the timing belt cover somewhere. It's leaking alot too.
This is just after a system flush so the flush probably cleaned out some corrosion that was plugging a leak or something.

I would have to say that is the case. There is NO WAY possible that putting the "wrong" coolant in will cause a leak this quickly. The wrong coolant doesn't generally cause leaks as much as it causes scale and deposits, certainly not leaks in the water pump. More often than not though deposits are caused by some pinhead putting city water or worse yet well water in the cooling system.
