Hi Mitz,
Seems like you've covered or replaced most of the cooling system, other thoughts are:
Is there an air lock in the system, possibly heater matrix, was the heater in the
full on position when refilled, does the heater work and drop the temps when full
on.
When you start from cold does the temp rise, then fall when the thermostat opens
and do the hoses and radiator gradually get hot. (watch you fingers).
Have you checked the plugs for any differences between cylinders also
is there any reason it would be running very lean, has the tickover increased at all
are the plugs white or the normal brownish grey?
Its a difficult one this if the guage is OK.Just thought is the system pressuring up as this
decreases the boiling point, check the expansion tank cap seal (carefully) or for any other pressure leaks.
Please please please be careful if you do any of this as super heated steam tends to smart abit
, I am not a mechanic and these are only
suggestions which might help, sounds like you know what your doing anyway.
let me know how you get on.
Regards,
Mark
