So I've had a leaking heater matrix for a while on my '03 Td5 Defender, 120k, with the usual dripping beneath it and fogging up the windscreen when it was turned on... I bypassed it by connecting the two pipes going to it and joined them with some metal pipe. When I disconnected the hoses to the heater matrix there wasn't any coolant leaking out, so just joined the two with some pipe and voila, leak fixed. Well, two days later and 6 hrs of off-loading in the "hills" here (everywhere else you'd call them mountains!) I've now got the leaking o-rings behind the water pump (coming from that little hole back there). There's no evidence of a head gasket failure (top hose is soft when fully hot, no contamination in the oil/coolant), as I was thinking extra pressure could cause some leaks. Also I opened up the bleed screw on the top coolant pipe while running, no air came out, just coolant.
So I'm thinking it's just dumb luck, that perhaps the heater was releasing a little pressure and now that it's not there anymore the water pump o-rings are worn enough they went too.
I'm waiting on a new heater matrix to arrive in a month or so, and now I guess I'll wait on the water pump as well.
Any ideas or suggestions? Thanks in advance.
