P38A [P38] Common coolant leak locations

It's definitely coolant, the puddle is a bright pink. Guess I'll be off the road for a while!

Are you upto speed lad

Catching up ... slowly!

Easy mornings work. Disconnect the rubber pipes under the bonnet and link them together, then you can use the car, heater not needed this weather.

+1 its an easy job to by pass under bonnet

There’s loads of threads in searchbar (top right) on it as most of us have done it at some point. It’s not as bad as you would think once you get stuck in. If you go full removal good idea to place the bits in the boot as you disassemble, then it goes back together quicker in reverse. Even LandRover eventually used the hole cutting method in the end

Wish I saw this before I started tearing the dash apart! Is it as simple as piping the internal (behind firewall )pipes to eachother and the external (engine loop) pipes to eachother?

Made a start today, got some bits off but got stuck because I don't have any eTorx sockets. Got some coming tomorrow.

Looks like the butcher has already had a go at this before, cut metal and quite a few missing screws:

No need to link the internal pipes. Use compressed air to blow the coolant out of the heater matrix.

Anyone know what diameter duct this is? May as well replace it while I'm here

Got the buggers out. They don't look in bad condition, got me wondering if it's a leak with the pipes or the matrix itself.



Anyways, what size o rings have people been using as a replacement? I've got some that are the same diameter but a little thicker.

If they have crusty crap on them it's because they've been leaking

I do not know the size, I just purchased the correct items, but a little thicker should be OK. Was the retaining screw tight? I suspect that the screw is likely to work loose with the heating and cooling cycles I put mine back with Loctite.

+1 on the loctite
The screw does tend to work itself abit looser during the first few heat cycles.
