    D3 2.7 coolant leak

    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??
    If at first you do not succeed, maybe your just no good and should quit!

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

    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 ****
