High Pressure in Coolant Tank –
17-07-2012,01:18 AM
As most of you will know I have just upgraded the turbo on my 1.9tdi. All is well and just doing a few MOT repairs. But I am not happy about the coolant. The main pipe that goes from the head to the radiator is really hot and hard after a run. And when I undo the tank cap it releases a hiss of pressure and the little pipe that goes into the tank shoots water through it into the tank. Just a bit confused as to why and i am not happy with it.
The only things i can think of are; the tank cap is blocked (already cleaned and blasted with an air gun), a blockage elsewhere in the system (going to drain and flush out thoroughly), the turbo is creating a high pressure inside the head....? (actuator not set up properly yet and running a massive boost!)
Any other thoughts?
