1998 Dodge Durango Overheating

Asked by GuruTG1HN Jul 28, 2018 at 09:13 PM about the 1998 Dodge Durango SLT 4WD

Question type: Maintenance & Repair

Was overheating, installed new thermostat, radiator, radiator cap and water
pump.  Still overheating and blowing coolant out of radiator violently when cap
was off and bleeding system after car came up to opening temperature and
started overheating.

So then:
Changed heads, head gasket, water pump, thermostat (AGAIN) and car still
doing same, overheating.

So then, changed raidiator again and still overheating but, noticed that upper
radiator hose stayed cool even when the car overheated.

So then, pulled thermostat to rule it out and ran car.  Still overheated with
thermostat out. Also, upper radiator hose still not hot when overheating.

One last note, clutch fan tested good.

Please help, I'm about to call the junk yard to tow away this money pit...

Sounds like a lot of air in the system.

Yeah, I parked the car on a hill and ran it, still didn't solve the problem. Maybe if I put a petcock on the heater hose and see if I can bleed the air that way.


jack up the front end as high as you safely can. use a radiator fill funnel kit, fill with coolant and let it sit over night.
