Td5 water leak

[LieutenantRover]

I'm losing water 1/3 from the rear of the engine LHS. Anybody know whats there that can leak? Frost plug perhaps, I can't see where its actually coming from. 1999 130 Td5.

LHS looking from front? = Fuel Cooler

BS226 Viton orings will fix it (from CBC etc)

Remove the acoustic cover and you'll see a cylinder shape...

Sorry its the passenger side of the engine.

Check where the bottom of the top radiator hose connects, it may only need the clamp replaced with a screw type hose clamp, those spring ones loose there tension after a while.

Check the whole hose too

If it is the LH side towards the rear, it sounds like the oil cooler.
The cooler can corrode the nipple where a short hose joins.

That is what happened on mine. I had had a slight leak the day before but
couldn't find where it was coming from, then next day it dropped all the coolant.

The cooler is not cheap:( from a dealer.

LHS at the rear could be a heater hose / bypass hose. Tucked down behind the turbo.

[LieutenantRover]

Thanks all. I'll have a look in behind the turbo in daylight tomorrow and post the result.

I hope Big Jon's right, that is the cheaper option.

Phil 633 wins the prize. Its the short hose into the oil cooler. How did you fix it. It appears to be the hose that is perished.

[Phil633]

If it is the hose that's ok, (I think that is the one Big john might be referring to) just get a new one from your favourite supplier.

I use Rovacraft in Bayswater.

I thought it may have been the actual cooler where the hose joins, that was my problem.

The hose from memory has a different diameter each end.

Oh, and I didn't fix it the dealer did, but that is another story

Brian - if you need any bits brought up and aren't in too much of a rush for them, I'm down in Perth at the moment and driving back up there on Friday.

Cheers ............. BM

Thanks, I haven't pulled anything apart yet as the water pump on the little tipper packed up. Thats first on the list for tomorrow and I'm sorting out the FFR (1980) one at the moment. I'll be in touch if I get at it by Friday.

Just so happens I have just repaired my oil cooler on td5 (1999 defender). The neck where hose joins to had corroded. Mechanic wanted $1700 ($1200 for new cooler), told him to **** off. I rang local spare parts and could get reconditioned cooler and gaskets for $600. Anyhow didnt need to. I pulled out existing oil cooler (takes about two hours-but pretty basic work), cut away the corroded neck and lathed up a new neck from alloy and welded it onto the housing. It welded well to the housing. Instead of $1700 it has cost me $30 for new gasket and four hours of my time.
