D3 2.7 coolant leak

[460cixy]

So I'm chasing a coolant leak on the left hand bank can't see any sign of leak from above from the egr cooler or hoses from underneath its driping down on the diff and it's all over the back of the ac compressor so it's coming from above that had a feel around the bottom of the water pump and that seems dry there I'm at a bit of a loss as to where it's coming from any ideas?

The plastic coolant housing under the throttle body?
For some reason it is called the thermostat housing but doesn’t house the thermostat???

That was the first port of call and it's good it's around the egr cooler but just can't spot it

It's likely coming from where the coolant exists the block on the left hand side of the engine. The alloy heat shields near the wheel need to be removed to see it. It's a **** job.

I have a spare oring here I can send you. Did you change coolant recently??

Yeah new coolant in it is it a bolt on fitting with an oring? Bottom hose goes to it?

That's the one!! What coolant did you use

The red coolant. Do you know what the outlets called or a part number I found it on a diagram but no part number I dunno if I could really be bothered digging in there you can't even see where that bottom hose goes to its crap. Edit I found it and of course it's plastic **** :bat:

If you need the oring I can send you one. If it's the same as the 3.0l it's a **** job but I've done it in a 3.0 with the compressor in place.. takes a lot of wiggling

You used genuine?? If it's the Castrol version that's why mine started to weep.. Also killed my float level sensor in the header tank. I use nulon now.

From memory, drain coolant, the front wheel comes off, the heat sheilds, hose gets disconnected at the other end. 2x 6mm bolts with 10mm heads. 1 hard to get at. Then it pulls out.. After half an hour or shaking it comes out.

Reverse process to put it back.. Although quicker.

The middle one is what you want. I have both these fittings waiting to change them so keen to hear how accessing the side of engine one goes.

Got the heat shields off today and it's that fitting that's ****ing out hose looks easy enough to get off ant the top bolt for the fitting don't know how I'm going to get to the bottom bolt yet I can't even get a hand in there to grab it
