Did you check if the cooling is coming on?
Do you have issues with the coolant level in the radiator? Check at cold engine.
Does the overheating occur only at high speed driving?
cooling fan comes on
no prior issues with coolant levels in rad
30-50 mph. It will run fine for 10-15 miles, and then you look at the temp gauge
and it is creeping up. throw the fan and htr on and it comers back down.
Appears to be an air pocket somewhere. Am leary about trying to find this bleeder screw people reference near the oil filter or if i even have one.
For 98 models, the bleeder screw has been dispensed. For bleeding, turn heater to maximum heat, run engine with radiator cap off till operating temperature, cooling fan coming on at least twice. Top up coolant if necessary. When coolant level is stable, close radiator cap and bleeding is done.
If you do not have lack of coolant in radiator, it is not due to air pockets. The cooling is inefficient and possible causes are :
1. Clogged radiator.
2. Thermostat not opening fully.
