Help!! Daughter in law's KA StreetKA has been overheating /boiling. Fan was not working so we did the following:
Checked state of oil for head gasket leak and as there is no water loss as such are reasonably sure H/gasket is fine, so we:
Renewed Fan temp sensor result.. Fan now operating correctly - still overheating
Renewed thermostat - still overheating (old one was ok)
Replaced Heater control valve - still overheating
Had no water pressure (no water coming out of heater hose when removed for test) so had water pump replaced. worked briefly and heater came on but then...... STILL OVERHEATING!!
Tried to eliminate possibility of airlocks by all suggested means..STILL OVERHEATING, and still no heat at heater in car. Totally demoralised now, can somebody please help as the garage is stumped.
