Engine Cooling problem
1998 Holden Vectra 4 cyl Two Wheel Drive Automatic 147000 miles
car overheated for the first time 2 months ago
it went from a normal 80 deg c to over 100 c
loss of most coolant
no heat into heater - not sure if hot water is getting there
actions so far
radiator removed and cleaned
radiator pressure tested and OK
maybe head gasket gone - been checked and 50/50
maybe water pump - seems to move coolant through motor
maybe temp sensors - don't know how many and where they are
possible reservoir cap leaking but this would be minor
no sign of water leaks under the car or anywhere inside the engine bay
what tests can be done to eliminate all the minor items before I get to the head?
what could be causing the overheating?
have the same problem?
