my jetta has always run warm since i bought it ,just lately it started running hot!!!
changed the thermostat ...nothing
waterpump nothing and finally the head gasket ...still running hot needed a head gasket anyway
finally i took the hose off the front of the motor ..and filled it from there ,mind you i was putting all the coolant in it i could at the jug on the firewall ...........
taaa daaaa!!!!!! runs cooler and better than it ever has ......i figured i had blockage somewhere and was close to tearing the motor back apart
on a seperate note ,how do i turn up the pump on this thing anyone have a diagram
thanks marcel
