Thread: TDI 300 Waterpump

Gday All
Changed the P gasket 3 weeks ago with a metal one. Noticed this morning after a 2000 km trip, coolant behind the waterpump pulley. Would it be wise to change the P gasket when i replace the pump as the 3 long bolts go through it. Thanks in advance

I have got away with it before, there is still one bolt holding pressure. On that note it's not really that much more to slip another P gasket in.

As 87county said use a sealant on the P gasket when re-installing, I would highly recommend not using 515 on anything to do with coolant though. I used it the first time I did my P gasket and it leaked about 25,000km later. I now use Loctite Greymaxx on most jobs

others have reported problems with new or relatively new pumps - perhaps it would be useful to search...

re the "P" gasket - current wisdom about installing seems to be to thoroughly clean both faces where the "P" sits and use a good quality gasket (eg. Loctite 574, 510, 548, 515, 518 Gasketing) on both sides of the "P".
