| I have a 2002 dodge ram 1500 quad cab with a 4.7 L v8 engine. It is over heating but it is not the thermostat or the sensor. A mechanic checked it. I took it for a short drive and it started getting hot and was leaking a lot of water. I had not been running the ac at all. when i pulled in and checked it i was able to touch the coolant tank and it was still cold but underneath it was hot. It seems like the coolant isn't circulating. I was told by a friend it was my water pump but how can i be fully sure?? What are the signs?? | |

| make sure thermostat is in there the right way. the water push's from bottom to the top. alot of people put them in wrong so no water flow | |

1996 dodge ram 2500 360 gas motor 4x4--245,000 miles with same motor and tranny.--- over heats when going uphill or pulling load(220 to 250 deg) but will cool down slowly going downhill back to 200 deg(190 in winter) hot days over 90 deg it heats up to 250 deg. In winter gets up to 230-235. Changed radiator, thermostat(failsafe), water pump, timing chain, temp sending sensor, temp gauge, flushed radiator, fan clutch, catalytic converter, O2 sensors, radiator cap, no milky oil on dipstick, tranny shifts good, engine lacks some power/quickness, radiator fluid needs 1 cup replaced every 1000 miles, engine runs smooth,#5 spark plug misfires according to the obd computer? what else could it be?? |

think I have found problem: changed thermostat changed plugs, wires, cap and rotor motor runs better still runs hot==then after stoped hot truck(240 deg) I felt the radiator core: bottom cold up to the middle towards top then middle to top was very hot radiator was only 2 years old. my friend who used the truck put that stop leak stuff in the previous one that had a small leak. so I think the new one only 2 years old collected particles from the stop leak in a narrow area in the new radiator causing the problem. I will flush the system to get more out and pull bottom radiator hose off when cool to quick drain engine of junk. then put new radiator in. |

Replying to: dooman75 (Nov 13, 2008 10:27 am) Second, what is the overheating symptom description? Does this vehicle overheat at idle, at road speed, etc.? Are you experiencing any coolant loss? Third, the heater core will not influence an overheating problem unless there is a leak which permits a loss of coolant. Regards, Dusty
