1995 Dodge Ram 1500 Q&A
1995 Dodge Ram 1500 Question: Why does my truck keep overheating?
I have replaced the upper, lower, by pass hoses, the thermostat (three times), fan clutch and the water pump.And its still overheating. I think its the radiator but I m not sure.I ve flushed it at least 4 times for 15 minutes each time. It is running hot because when I turn on the defroster the hi. It blows hotter than normal. - Burch
"It is running hot because when I turn on the defroster the hi. It blows hotter than normal." That's the reason you think it's running hot, the defrost is hotter than usual? What does the temp gauge read? Has anyone actually used a scan tool and got the coolant temp from that? Hooked up a stand alone temp gauge, put a thermometer in the coolant? Maybe you just need a cooler thermostat. - Pvt-Public
Cuz if theres one thing I know is, I know my truck. It is indeed overheating. Im a mechanic who was in the the Marine Corps. I go with my gut. My gut tells me its the radiator. - Visitor
you may have a craked head gasket ,small leak can put pressure in a coolant sistem (do a compression test and a coolant sistem presure test too ,if the coolan sistem reveal abnormal presure (hight)you have a head gasket problem ,also apply pressure in the upper hose if you feel to much pressure is kind a head gasked fail and check for bubbles in the radiator - Visitor
