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?
:smiley:

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

have you bled the system properly

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

Yer mine does that, when It can be arsed. Will check it now :smiley:

Mine left ticking over:
the fan cuts in and out quite frequently, oil temp cycles between 100-110 deg. temp gauge pushing towards 3/4

The fan is fed a permanent live from battery via temp sensor (switch) so you won't even need the keys in, hence how the fan can run on when just parking up and getting out of car. As matey says short the permanent + switched feed (2 wires) out and it should fire up. If not, wiring / fan motor at fault.

when bleeding leave engine at idle speed and take cap off expansion tank allow to warm up leave heater on hot and set fan to 1, you will see lots of bubbles and when thermostat opens you'll see level drop significantly top up and keep watching the bubbles just as the level in tank starts to rise out the top put the cap on. also while its warming up squeeze as many pipes as you can b4 they get too hot
did you fit a new genuine thermostat?

No not genuine.
I managed to electrocute myself but the fan does work so faulty thermo is the issue, cheers for the help lads. She is due a good service anyhow.
