Title: coolant leak problem
Post by: oceanic-green on 31 July 2012, 14:16

I have pink fluid over my gearbox, which seems to be coming from the corrugated pipe shown in the picture with the green arrow. How do I go about fixing this? I have never fixed coolant pipes before, only boost and pcv pipes.

dont think its coming from the corregated pipe, thats wiring in there.

Ive got a coolant leak in the same area lol I think it's the rubber O ring in the plastic bit that bolts to the head where all the water pipes go to in that area

+1 itll be from somewhere near it and getting splashed onto it, check where the sender is and surrounding area

Im assuming you have a 1.8T?

If so it sounds to me you have a leak from your Thermo area, the rubber ring sounds like it could of failed, check where the thermo goes and see if you can see anything.

I thought it was, as I had it changed about 3 months ago.

Must be some pipe that is split above the corrugated plastic pipe then, I will have a look. But in two days my coolant level has gone from max to min  :sad:

Would a coolant leak cause the ecu to use less power?

in what way mate?
didnt make sense

Its only a theory as I am not ssure how engines work that well, but maybe if the engine isn't being cooled properly then the ecu might put it in safe mode by not using as much power so it doesn't get as hot as quick..maybe..maybe not  :undecided:

Just me trying to understand these complicated machines  :laugh:
