Minor Coolant Drip

[ldrhoades]

Have spent a good part of the morning sifting through the hundreds of posts/questions on coolant leaks. What I have barely qualifies as such, and it is really more of a drip or two, and only after the engine is hot, as it cools it stops. I was having my car teched for DE and asked the shop to look into it and they said it was a "bypass valve gasket" leaking that needed replaced. I didn't see anyone else experiencing this problem. The shop isn't a Porsche specialist shop so I'd love a second opinion. Alos would appreciate the part # of said gasket.

Thanks in advance!

Where is it leaking from? The thermostat housing gasket?

Lennie:

Are they perhaps referring to the bleeder valve assembly that sits on top of the coolant tank, forward of the coolant cap and under the small black plastic trim that covers the top of the coolant tank?

Let me try and upload a pic (sorry about the marginal quality)...

That is your thermostat housing gasket leaking.

To avoid or minimize draining the entire cooling system, use a pair of hose pinch pliers to clamp the coolant hoses going to and from the thermostat housing before you remove the housing to replace the gasket.

The part number (for just the gasket) is 996-106-326-50 (about $4.00).

Thanks Maurice. I appreciate it!!!

That is not the theromostat housing. Thermostat is on the other sdie of the engine at the water pump. However, you will need to collect the coolant when you remove the 4 -10 mm bolts to replace the gasket.

Make sure the leak is not coming from above.

Finally got around to ordering the part number referenced above. It is an odd shaped gasket, not the rectangular one that I need. Can you double check the part number?

Thanks,

The gasket number specified earlier in this thread is the incorrect part. You need part number 996 106 316 51, as shown in the attached pic captured from the 996 PET:
