running hot - help

<< < (3/11) > >>

drmike:
Just how hot is it running?

I believe that antifreeze isn't a very good coolant so that you're now using a liquid that won't cool as well as the weak solution that you had before.

Then again it won't make that much difference although I certainly saw a change in the normal temperature when I watered my antifreeze down.

Cassillis:
o you have heat at the windscreen via the blower? If not it is airlocked. Try this first.  It may be the water that is reaching the thermostat is not hot enough due to the airlock.

Two things to try
Blower and heater on full and gently rev her to about 1500 see if this pulls it through
Secondly
Try topping her up from the thermostat housing instead of from the header tank with hot water so activating the wax pellet that sits in the thermostat causing it to open and allowing circulation.
Hope this helps

LCW11:
Not sure we have established if its over heating or not
 :roll:

By bet still lies on a faulty gauge or electrics

TDi90:
overheating... well i dont think so but where do you draw the line??
i mean, there have been no effects on the engine, or the running of rolly, but, the guage reads between half, and the Red.
