Water Pump Gunk

Resurgam · Oct 27, 2020

Has anyone ever found anything like this horrible looking slime and crystals lurking in their cooling system? Hopefully it's not a sign of anything more serious. It's only ever had proper coolant in the system, so I'm a bit surprised it's so bad. I'm going to replace the pump as the impeller is looking a bit flaky (literally), although there's probably still life left in it.

Looking around there seem to be three options (or four if you want to pay Land Rover £275). Would it be better to pay a bit extra and go for a Proflow one (who seem to be the OEM), or are Bearmach or Britpart ones actually alright?

Looks to me either a cooling system that has had just plain water, a good flush wouldn't go a miss

Someone may have put a sealant of some sort in there at one time - or even an egg ...

i had a britpart one and the impeller came off the rod bit, might not happen to you but i would go OEM every time.....

See that tide mark on the impeller and in the block? i would say it has sat with low or no coolant coolant for quite some time.

You're spot on there. It's been sat for ten years and when I started the rebuild there was no coolant to be seen. The radiator was pretty shot so I think it all escaped that way.

Thanks for confirming what should have been obvious really! That's been my approach to most of the rebuild. OEM unless it's not critical.

Could be. It didn't happen during my ownership though - honest.

yeah I had to strip it all down again within some 6 months or so, my thinking was ‘how can they get a water pump wrong’ but clearly they did!

agreed OEM for critical or structural stuff tbh

Maybe fit the old pump and add some central heating cleaner, and run for a few miles, then dump the lot refill with fresh water do the same again, then new pump and coolant?

Sounds like a good idea. Unfortunately the day I'll be able to drive it, or even start it up, is a distant dream! I'll give it a flush out with a hose and see what happens.

Kilrock Big K kettle descaler is also good gear, has to be used with hot water, cleaned out my old series 2 rad pretty good.
