Over Heating Promlem!
« on: 17 December 2010, 15:52 »
Been a good while since ive been on here, but unfortunitly ive got some trouble with the car over heating!
Problem started last week (car has just been serviced in the mean time) Driving home the car seemed fine, but after i started putting the toe down it soon started creaping up again, seems to drive fine but soon as the turbo spools up the temperature flies up!

Also the cars just hit 60k so its due a cambelt & waterpump change, do you think this would resolve the problem?
I just cant understand why its not over heating constantly  :shocked: seems to be only when i put the toe down :S

Any help would be greatly appreciated!!

Might be a whole different story if this was a problem in the summer  :sick:
Got the right mix of anti-freeze?
Is the thermostat stuck closed?
Water pump could have fallen apart?  Can you see the coolant is flowing back up to the header tank?

If the water pump etc is due, get the thermostat done at the same time and replace the coolant with proper VW G12 stuff.

convection, thats why it isnt happening when you are stationary or traveling slowly. its so cold outside at the moment and when the engine isnt racing it is enough for the engine to cool by convection but when you put that load on the engine without the water circulating (pump failure) it just boils up the water in the block as the coolant is staying put for too long.
that`s my idea on it  :nerd:

Defo sounds like water pumps failed, the plastic splits  from the metal shaft.  Your best option is use the metal version from GSF.

Defo the pump  :wink:

Just get a genuine one and make sure you change it at EVERY cambelt change. They are now made from an uprated material and will out last the cambelt  :smiley:
