Water pumps can leak intermittently. So can hoses and connections. From that
area it is either the pump or the hoses to the oil cooler.

Subject: Interesting coolant leak - well it is for me.

So a few weeks back I noticed some coolant had leaked from the van as per a
6" diameter coolant stain in the parking stall under the motor (2.1 digifant
- 1986).  I noticed that the coolant had been dripping from what appears to
be the bottom of the water pump - however I can't confirm this as the oil
cooler obstructs my view from looking directly at the water pump.  (Water
pump replaced approx 15k miles ago)

Anyway I drove the van basically to work and back for a few weeks (short
trips) and the leak seemed to go away - no drips.  What I have noticed since
this time is that once I get the engine warmed up to normal operating temp
the dripping coolant returns - leaking out from up and between the oil
cooler and oil pressure relief valve.  Looking down at the engine through
the engine bay and with a good light - there is nothing to see leaking
either.

My short trips to work don't get the vehicle up to normal operating
temperatures so this dripping doesn't happen that much - and the amount of
coolant typically lost is about 1/4 cup.

Any thoughts on what might be creating this?

Thanks,

Bruce
