Coolant Line Gasket Replacement

Recommended Posts

In October 2005, I removed a coolant line cover (996 101 021 01) that also fastens the bolt (996 101 021 01) for the alternator. See illustration 101-05 in Boxster shop manual.

I did this to make it easier to shove the alternator into position on top of the block but under the intake "ribcage."

Wrongly, I did *not* replace the gasket (996 101 331 50) and I believe that is now why I am now leaking coolant onto the plastic undercarriage panel. By the way, a word to the wise from the unwise: this appears to be a less-than-$5.00 part that could have been replaced the first time.


My questions are these:

1. Do I use any kind of form-a-gasket material to seal the gasket (996 101 331 50) when I replace it?

2. What is the torque value for 996 101 021 01?

1. Its usually an either/or on German cars. So if a part is designed to use a gasket, the gasket is installed dry. All gaskets on the cooling system are installed this way. The crankcase halves do not have a gasket, so are assembled with a mastic of sorts.

2. I'm sure the bolt is meant to be 900 378 030 09??? If so, 10Nm
