Hiya,

my van's sprung a leak, seems to be coming from the water pump to engine join, which I know from bitter experience is a bitch to get at.

weird thing is it only leaks when cool...

why would it start leaking when the seals are un-disturbed?

where's cheapest for a new pump, and how much are they? wondering if I should replace it if it's got to come off anyway...

by the way, it's an '89 dg with the more sensible pipework.

Try a spanner on the bolts. Leaking when cool(I guess after running a bit)... increased presure..... Not leaking when hot..... Every thing expanded and sealed the joint.

Dave, I think you will find it really is your water pump that is leaking and belive it or not it is designed to do that once it gets to a certain age.

Aftermarket pumps are good enough to do the job, and will test your skills as a mechanic when you come to replace it..........Go for it if it wants one Just do it.........

Fritz,

Where does it leak as an indicator of age?

There's no leak from the pulley seal, definately from the back where it joins the block...

Plus maybe it only appears when cold cause it's not evaporating? It is a small leak...

Dave

part number 025 121 010 BX £38 from VW ex vat includes the seal and gasket.

Dave ,sorry for the poor explanation,,,,,,,,You may find water will bypass the spindle seal in the pump and then run down the casing via the hole on the underside of the pump.
My guess is they are designed to do this to indicate an imminent problem.
