Ford Falcon Au (1998) with over 200,000 klms. We are having a problem with car over heating on hot days (on normal and/or cooler days the car runs fine and does not over heat. ALSO the car over heats when the air conditioner is on higher and/or going full blast while the car is in park and/or is idling, however the car does not over heat when the air conditioner is on and the car is in drive and moving down the road and/or down the street. We have already replaced (over the last 2 months) the radiator, and the thermostat housing; and have ensured all hoses are secured properly and are in ok shape, also there is no water is leaking from motor and/or onto ground. The car is a 6 cylinder, and has been fitted with gas. So the car runs on dual fuel. Other repairs to the car have been the oil pressure switch has been replaced and there has been a major transmission service done on it within the last 4 to 6 weeks as well. Any ideas what else might be causing the over-heating. Water pump? Or something else?
