how do I fix overheating problem in my car peugeot 405SR. manual ) have changed my radiator, water pump, but stil it overheats. Is there any connection with the car air conditioning unit.
Does it overheat when moving or just when standing still? If it gets worse when stading still check that you fan is working. If it is electric (most likely) you'll see and hear it come on. If viscous, the hub should lock up. Be very careful when cehcking viscous fans - they are dangerous.
