Title: Coolant!
Post by: 92UrS4 on September 18, 2006, 10:14:24 AM
Got the th ol Pasat yesterday, started it up, BEEP BEEP BEEP BEEP BEEP BEEP BEEP, I look at the dash..STOP Check Coolant Level. So I turn off the car, pop the hood, I have just about no coolant. I see no visible leak. Great.

I rode the BMW in today, getting ready to head to the dealer to pick up my $22/gal jug of coolant. Just so I can drive the damn car in. Fortunately it is due for its *gasp* 20K service.

Have you noticed a leak anywhere?  If not, the only other place it could be going would be out the exhaust 8O Not good either way.

Right, or through the head gasket?

Mysteriously dissapearing coolant != good

Any white smoke on start?

Which would eventually head out the exhaust...if you're leaking coolant out of the tail pipe any number of horrible things could be at issue.  Any other driving issues - hard start, knocking, slower acceleration, etc?

Well... yeah, heh. :D

Good luck Jay, I really hope it's just a very small hose leak somewhere! The white smoke would be an easy way to tell if it's blowing out the tail pipe, if the amounts are significant enough.

Thanks guys, i am aware of the typical causes. I gave a quick once over, the 2.0T is configured a bit different than the 1.8T was. My old 1.8T had a recurring  problemat teh turbo, bad fitting. Would just leak a little, pressure based,, I would never see the drips because of the bellay pan catching them all (blessing and a curse those damn bellypans). Took VW dealers almost 3 years to fix that one right.

I just picked up a gallon fo coolant and scheduled an appt for Wed morning.

Now, I sit here typing this and have noted a few times this summer launching from teh wait light on the entrance ramps that I saw a puff, but that could be moisture.

I noted to myself that in the last couple weekd the coolant level while cold looked a little low (just below the min mark) but I knew I would be taking it in for service in teh coming weeks and said I would watch it. Everything seemed normal until yesterday. Which was hte first time I got the warning light and I don;t really drive my car that much right now with the decent weather and the BMW. :) I think I ahve only gone about 200+ miles int he last 3 weeks. Not too shabby when you have a 50+ mile a day commute.

Thanks for the ofer Eric, I just went and bought some at lunch while I made the appt. It never hurts to have some for times like these.

Jay:

The first thing I would do before starting that motor again is make sure you do not have a head gasket problem.  I'd be cautious about driving a car if you really think you might have a head failure (get a tow truck...).

One way to determine head gasket failure is to examine your motor oil.  A head gasket failure will often mix oil and coolant, and your oil will be the wrong color and texture (I think I recall my oil becoming sort of white creamy when the HG failed).  A second way to tell is to listen to the motor when it is running (this is not the best way, but...).  You will hear much more valve clatter than normal.  Putting a stick on the motor and your ear on the other end can help you listen to the valves (really, I'm not putting you on here).

Most likely, you do not have a HG failure.  I'm guessing your coolant leak is near a place that hides the leak well, eg, near the radiatior and fan where it can evaporate quickly.

Good luck.
