Coolant Resevoir Leak


Recommended Posts

Well, I suffered the Coolant Reservoir Leak that seems to happen to many 996s. I thought this was a non-issue for the 00s (I have an 00 C2 Cab). Anyway, the dealer assured me that this won't happen again due to a thicker tank used on the 03s and newer. IS that true or will I have to suffer through this again?

The total replacement cost was US$650 (labor $350, parts $300). It just kills me to pay the bill when this is a manufacturing defect. At least if I knew it won't happen again I could feel better about the situation.

Anyone have any thoughts?

There have been 3 tanks for the MY99-00 Carrera's

996 106 147 54

996 106 147 55

996 106 147 56 (this is the newest one)

For MY01-02 Carrera's there has been another 2 tanks:

996 106 157 01

996 106 157 02 (this being the newest)

For MY03- there has only been 1 tank (so far):

996 106 157 03

There is no guarantee that it won't happen again - but most dealers give a 1 -2 year warranty on their work.

Oh... and make sure your cap (for the tank) is the newer one - it should be 996 106 447 01. The 00 version is known to leak too.

I've never heard about a coolant reservoir tank cracking on any other car.

My Bike's tank cracked a while ago. It cracked/split along the seam of the tank due to the plastic material being very thin.

Luckily I was able to perform some plastic welding along the seam to repair it.

You will find that the problem with the 996's tank is confined to the earlier models and hence the model/design changes as noted by Loren for the relavent MY.

DOH! On a similar subject, my water pump broke yesterday and left me stranded on the side of the road. It's a 2002 coupe with about 94,000 miles on it. There was coolant all over the engine compartment and back of the car. My serpentine belt broke too. I had it towed to a dealer and haven't heard back with a diagnosis and price quote yet.

Does anyone know what the official price is for a water pump and the amount of time that it is supposed to take to replace? Thanks.

Let me ask a stupid question.  Exactly how/where/why do these tanks crack?  I'm just curious because I've never heard about a coolant reservoir tank cracking on any other car.

Heat or something gets to them and they become porous. Maybe because the mufflers are right there... who knows. Edited by PTEC
