Disaster Water Leak

[me&mygt]

Well i did what all good TOC owners should do and gave the girl a service on Sunday. During the process i did the coolant change and flushed the engine and radiator. Thought i'd give rapid flush a go first and then flush and fill with coolant. All went great and i was very satisfied by the end of the day. This morning i got up and i had coolant all over the drive, after refilling i've goy a leak at the back of the water pump, never been there before. I've spent all day trying to seal it to no avail. What do i use? Will i have to take the pump off and does that mean engine out? I'm a bit angry with myself for using that stuff. not a good idea for the future.

Sorry to hear that; I can't say I've heard of such a thing happening before.

I wonder if perhaps the previous owner had used some Radweld or similar to correct a problem and the flush removed it? If that were the case, then maybe you could reseal it with more Radweld, though that's always a bit of a risk.

Alternatively, if it has destroyed some seals, then perhaps you have a case against the manufacturer of the flush; though I guess it could be difficult to prove that the problem wasn't already there.

Good luck; sorry, can't offer any advice on replacing the pump, though I would say that I'd be amazed if changing the water pump and its gaskets needed the engine out; it's a part that manufacturers must know will fail eventually so they should have allowed for reasonably easy replacement surely.

One other thought - isn't there a drain tap on the block somewhere near the water pump; is it possible that that is the cause of the fault if you used it when you emptied the system; perhaps it hasn't closed up properly. Water can so easily move about and look like it's leaking from somewhere other than where it really is getting out.

cheers. think you might be right about the rad weld. seems a bit odd that it has sprung a leak just flushing it out.
