Overheating

[Sam]

MK2 16VT is overheating in terms of water, oil gets high too but only hit 104deg max so not worried. I noticed the expansion tank has no water in and there was water sprayed around it, I took the lid off and it all came back through as if I had releised a load of pressure then bubbled down slowly and now has nothing in again with the lid off. Do I need a newcap or do I have bigger problems?

Clearly not the same thing, but my fiat used to do that and it was because the head gasket was going.

Is the radiator fan kicking in and out? oil temp on mine reaches 110 deg when its in traffic. Is your cap blue?

Cap is blue and the rad fan doesnt seem to kick in, I noticed that but the fan not kicking in shouldnt cause so much chaos

You think this should be first call? To bleed the system and start again?

Yup, the water will start to boil and spit out of your cap. short the 2 wires together on the therm switch (as your looking down at your rad there is a sensor bottom right, screwed in to the rad) If the fan cuts in its that thats fooked
