just been on a 40 mile round trip, running temp was past its normal temp posistion.
when i stopped i immediately checked the viscose fan , and it turned exactly the same as when its cold.
is that right.
i have recently changed the head because of over heating ,bought a new radiator and loads of bits of pipe. took the thermostat out and drove it for a few days , and the water rushed through the system , so the pumps ok. thermostat opens properly to.
