Hi everyone, my p38 was origianly a auto and at some point someone has changed it to manual, ive just had the head skimmed, and have been running the car without fault, then we noticed it has a water leak from the Center of the car, once on the lift we noticed two pipes from the radiator,one from the Center one from near side, these go direct to the transfer box, the leak is between the two faces of the castings. The only proper way to fix this would be to take everything to bits and repair the gasket / face, howevery question is do I need it ? Everyone I've spoken to has said they have never seen one water cooled, but once shown they can't work out why it would be needed, so can I just link the pipes together and bypass the trasfer box ? I travel about 100 miles a day park up for 5 hours and then drive back home, I consider this motorway driving as normal use not high use, I don't tow a trailer or carry anything above its carrying capacity, would the box over heat ? Does anyone else have water cooled manual box ? Has anyone else come across this problem ? How was it resolved, would greatly appreciate any advice to fix it rather than set fire to it lol ! Thanks
Water leak from transfer box ?!!!!

I am at a loss, I have never heard of a water cooled TB either....
A P38 will never generate that much heat so I am sure you can bypass....photos would be nice!!

Are you sure that this is water?
The only thing that I can think of is some sort of bodge involving gearbox cooler pipes and a rad with a built-in cooler. The transfer box should be 'full' of ATF so, is the leaking fluid red?
As for - do you need it? Well I'm running my diesel auto with a fog light blocking the gearbox cooler with no issues so I can't imagine that you're going to need cooling in your transfer box.

The R380 box has an oil cooler located in the bottom of the radiator. I suggest this has ruptured internally and coolant is leaking into the gearbox oil. New radiator and drain and refill gearbox.

Think his description was out a little. Oil cooler pipes go on R/H side of gearbox just short of Transfer box. Only pipe connected to that should be the breather i think.

Two pipes direct from radiator straight to transfer box, not a bodge job, There's two pipes one in the Center of the rad one to the far near side, both at the bottom of the rad. There go straight to transfer box, it's water that's coming out with antifreeze in it. The pipes that go into the box are steel, there's no oil cooler, well if there is I can't see anything unless it the ram air type oil cooler that sits behind the rad, but it's not them pipes.

I think they are the manual gearbox cooler pipes that go to bottom of rad, new rad and drain and flush gearbox oil like Wammers said.

Manual gearbox oil cooler is in bottom of rad and part of it. Cooler pipes go to side of gearbox. If you have water in those the cooler part of rad has ruptured and water is leaking into oil cooler and so into gearbox. The oil cooler adaptor bolts to the extension case that houses 5th and reverse. Not onto the transfer box. Drain the box and see what you have in there. Only cure is as i stated earlier.
