hello all thought i wud try steel seal for what i think is my head gasket gone, did what it said to the letter and dident work!! ive got loads of pressure in the expansion tank and its leaking out, so i think that has to be the head gasket leaking and pressurizing the system, took it out today and the heater blew hot for a while then went cold, but after the run i noticed that the radiator was cold? thinking blocked radiator? wud this cause pressure in the expansion tank? so just want to be 100% its the head gasket ,, any help guys car is Citroen c5 2.2 hdi

Thanks

The system isnt air locked is it.I put a radiator on a subaru forester last weekend and it took about 2 to 3 hours to get the coolent system to bleed.The radiator was stone cold and the coolenr kept on pressursing and spitting the coolent out of the tank.

I just read about these and some one mentioned plastic water pump impeller coming away from the shaft. Might be worth a try

Would it work on a high compression derv motor?
A local garage could probably do a coloured water test from the header tank to prove it?
Otherwise a compression test, no doubt quite awkward on them.

have you checked if the water pump is pumping? remove the small bore return pipe from the header tank and while it is running check to see if a constant stream of water is coming out

As above. Sounds like water pump failure.

Check to make sure the header tank cap is working right. Go buy a new one for a couple quid before going any further

the silly thing is it doesn't over heat and the engine still sounds and drives perfect, i still run it and keep it below 2000 rpm, masses of torque as its the 2.2 hdi de-cat and Dpf removed...
