99 Dodge Grand Caravan running hot
I've replaced the radiator, hoses & thermostat but it will still run hot every now and then. The tricky part is there are no visible leaks. Any ideas??

Could be a head gasket. Are you getting white smoke out the tail pipe? Are the electric fans kicking on? Is it losing coolant, or just running hot?

Are there electric fans? Be sure those are coming on when they should.

Also the temperature sender for the gauge in the vehicle and/or coolant temperature sensor for the engine computer can be giving false readings. Although when I have had those go bad in the past, they indicated too cool. But might want to test those as well.

Complete testing and troubleshooting instructions would be in a 99 Dodge Caravan factory service manual set of books. Order from dealer or online at
