Does this look like a failing expansion tank cap? My part # is 996-106-447-01 and Pelican shows 996-106-447-04-M100 - which I assume is a revised and newer part - based on the 04 at the end. I have cleaned it up to see if there is a leak, but for the $30, maybe it just makes sense to replace. Query - Would this kind of failure cause operating temperatures to be higher than normal?
Replace the coolant expansion tank
or your help guys, I've just pulled the carpet out and no signs of any coolant. Everything's dry and no signs of any previous leaks either. I had a look at the coolant cap and the part number on it is 996.106.447.01 so looks like that needs replacing. I then lifted up the plastic horizontal plate and there was lots of signs of moisture and coolant in the little gaps and corners so definitely looking like it's the cap. Will get a new one ordered asap
