Coolant Leak / Overflow ???

[Lil bastard]

All good answers. There is another possibility, that a clamp is leaking. Porsche uses a spring clamp, but has issued a TSB to replace these with conventional screw-type worm clamps whenever any of the originals are removed for service work. You're gonna need to get under it to see what more you can find.

If you continue to drive the car w/o addressing it, whatever the problem is could leave you stranded.

While it certainly could be the reservoir, especially w/ a '99. Porsche has since changed the type of plastic being used and it's much rarer on the later cars. If that's what it turns out to be, be certain you get the revised replacement tank. I believe the most current one is PN#996.147.106.07. Good Luck!

So something is obviously wrong.
How could it be the coolant cap alone causing this?
Also, should I get the car towed? (the dealer is about 30 minutes away)

Thanks Again!

I think the earlier caps released pressure faster than the newer ones, or something like that. Regardless, this was a known problem, and hence the update to the 01 cap, and more recently, the 02 cap.

I think you'll be ok driving to the dealer. Just bring like a gallon of distilled water with you in the car, just in case.

My car had a coolant leak in the middle of the car in the passenger side, the leak wasnt that big but it ended up being the water pump.

So it is probably one of these:

Coolant Cap
Cracked Coolant Tank
Water Pump
Clamp

I have an extended warranty ($80 deductible) which should cover any problem. Is there any way to be certain whether of not it is the coolant cap? I would prefer not to pay the $80 deductible and find out the problem was the $17 coolant cap.
I have an older coolant cap (.01). I also cannot see any coolant reading, it is either too full or too low, to be read.

Also, is there a drain on the coolant tank? How did all this coolant come out if the tank isn't cracked?

Thanks Again!

Check underneath the car. If it looks like there is a small hose that fresh wet it's probably the coolant overflow hose. Did you mess with the bleeder valve recently? When you topped the car off was it on or off?

[rick3000]

I have not messed with the bleeder valve, but it was recently at the dealer, because it was heating up more the normal, and they may have messed with the coolant tank (I know that they pressure tested it).

I am going to check everything again tomorrow, and maybe take it into the dealer.
Could it be as simple as overfilling the coolant tank when I topped it off, and it just drained the excess coolant?
If the coolant level is normal, would that signal nothing was wrong?

Thanks!
