Water leak

I have a slight water leak. It appears to be coming from the core plugs and I was thinking of trying some radiator seal in the water till I can get it sorted. Anybody know of a good brand?.

No, get it sorted

Asking for a world of pain

Okay chaps, I bow to greater knowledge than mine. Will get it sorted, but it will have to wait a while, I am to busy at the moment, and besides it is to bloody cold to mess about with a Landrover.

We're abouts is it coming out as mine was from under the manifold very easy job to remove the manifold and retighten them

Yes, there is a 'feather' for want of a better word, of pink coming from behind the exhaust manifold.

I agree with the rest!

After having 2 goes at sorting out a water leak (read - overheating) I found on my 3rd attempt that the rear block core plug had rotted through at the bottom (engine out!!).

I have since replace all 5 core plugs in the block and those in the head too. Having spent so many hours/days taking out the engine, sorting minor oil weeps, cleaning up God knows how many months of old oil and goo all over the axle and chassis I intend to do as much as possible to prevent a future issue with the damn cooling system! It's had a new expansion bottle and cap, water pump, head skim, valves lapped, new gaskets all round, complete cooling system flush, oil change. I'm now just waiting for the bits to finish the re-seal/refit of the vacuum pump (Wabco cr*p) and the refit of the front casing that holds the steering pump and alternator. I had to remove it as I found out that there was a 53mm core plug behind it that I did not know about and of course it was AFTER I had refitted the engine

So fingers crossed that I can at least get a few hundred miles out of the truck before the next 'mission' begins

So if you can get at anything that does/may leak then do it now rather than have the grief I have had.

PS. Sorry for the life history

Running without the proper coolant won't help, the LR OAT coolant is a very strong corrosion inhibitor.

I bought some for my Mercedes Vario the other week and it's damn near identical, and half the price, even if it it Mercedes approved.

Opie Oils are good to deal with as well.

The general consensus is that the OAT-type coolants don't agree with the composite head gaskets in the 300TDi, so I'm going for the standard Ethylene Glycol stuff. The last thing I want to do is have more leaks after a few weeks!

But I agree, I reckon the state of the coolant I took out originally and the lack of metal inside the offending core plug she hadn't seen decent antifreeze in a long while!
