Hi,
I have a slow intermittent cooling leak on a Cav 1.7TD (isuzu). Sometimes there's a slow drip of coolant from the bottom of the engine near the crankshaft pully. I suspect its probably the water pump but can't actually see any leakage from the pump (although there's some oil/gunge which could be masking it) I'm fairly sure its not the connection from rad pipe to block. Is there anywhere else it could possibly be leaking from e.g. a core plug or something hidden under the cambelt cover? Replacement of the pump looks to be straightforward, yes?
Thanks
Jim
