Zetec over heating, HELP PLEASE
Hi everyone, I have a mk 6 fiesta 2006 1.6 zetec s and it over heating!
I have had a look today and....
Top water hose is boiling and bottom is freezing!
Heating inside car is cold and gauge on dash reads normal but header tank is bubbling hot!
Done a sniffer test and a compression test that both come back fine!
I have taken the thermostat out and checked that it opened ok!
Do you think it's a water pump???
Cheers
Danny

on the late ones the waterpump holds the timing belt tensioner so you need to do a belt kit aswell
if you took the stat out and its still boiling over id have a look at the waterpump, although they are metal impellors

Little update (still need help)
Had the water pump off today... They are plastic, but its fine!
I'm really baffled now!.... Had a few people suggest head gasket but I'm not convinced + I've done a sniffer test & compression test that both came back fine!
What else could it be?

ooooooooooooooooooh also, one thing to check that ive came accross a couple of times
on the back of the head, theres a small pipe that comes out of the head (g/box side)
the aluminium 90degree pipe currodes and blocks solid with currosion and shyte, make sure the pipe is free and the hole in the head is too!
this is the "bleed pipe" that returns water/air to the tip of the header tank
