hi jasso, I would recommend checking the water pump if you see no flow in the radiator. Make sure when you fill up the cooling system, that you fill it cold, and that the vent screw in the radiator is loose. fill system until fluid comes out the vent screw. tighten the screw, start the car and have someone run at 1500rpm and check for flow.also, make sure that you have your temp setting full hot and blower on middle speed so that you don't trap air in the heater core.

have you ever replaced your fan motor? if no, have it replaced.. if yes, you probably need to replace your radiator. try to get those after market aluminum radiators. This will give your car better cooling.

Its also possible that your car's alternator is not at its best anymore thus giving low amperage to your fan motor and other electrical devices. this will slow down the RPM for your fan. This will cause your engine to overheat due to insufficient cooling.

SOURCE: 2002 dodge 1500 Changed radiator, thermostat, and hoses. No heat

Why was radiator replaced?Did it have heat before ? If it was plugged, the heater core may also be plugged. Try flushing it with a water hose in both directions. I dont know why the botton radiator hose would be cold, the radiator should be a uniform temp and the air coming through the radiator should be HOT, when the engine is at operating temp. What condition was the old coolant? if it was rusty, the water pump may have lower flow than normal.

If my top radiator hose gets hot but not my bottom one does this mean my thermostat is bad


I don't know how did you test your radiator but if you apply below steps you can clarify your problem easier.

If you want to test your radiator:
A) Park your car (it takes more longer to get real temperature values, if the car is moving)
B) Start the engine (don't forget to engage handbrake)
C) Wait around 10 to 15 minute
D) If your top radiator hose gets hot and bottom radiator hose gets warm; your radiator is functional. (In few minutes your radiator fan suppose to work)

If bottom radiator hose is still cold, it means there is a problem at thermostat. If you see any leakage at thermostat housing at the end of above step C, you need to renew thermostat housing gasket too. Even if you buy new thermostat, i suggest you to test it before assembly. If new thermostat doesn't open enough, your car may run so hot.

If you would like to test your thermostat:
A) Boil water in disposable bowl (thermostat may exposure chemical substances)
B) Put thermostat into boiling water.
C) If thermostat opens totaly, it is ready for assembly.

The radiator could be plugged up from corrosion, due to age.

I'm BAFFLED with a heater issue. Heat went off in my 1991 CRX SI with no apparent reason. Car is not overheating. Coolant in tank is full and it's clean. Top radiator hose is hot; bottom hose


Check the PUMP, there is apump that pumps the coolant from the radiator into the engine, if its broken you will have that problem.

I keep overheating changed out thermostat and fan and still overheating I fill the hose with coolant and it all goes into the overfill tank and gets hot and boils out


A clogged radiator could be your problem. Flushing won't necessarily clean out a clogged radiator.
When it's idling and getting hot, the clutch fan should be running full on, actually "roaring" as some say, and the electric auxiliary fan or fans should be on if you have them. Also test your radiator cap, replace if needed. Hope this helps.

My VW Cabrio is overheating after 1-2 miles. Coolant in recovery tank is boiling by this time and making bubbling noises. Someone changed radiator hoses, flange, some housing. They are saying that radiator...



Run the engine and look at the header tank , is there lots of air bubbles coming back out of the water if is then the head gasket may have split and that is down to either a can of Radweld or a strip down repair

If the radiator is not uniformly hot them I would go for that as your problem

Normal operation is that the engine starts the thermostat is closed , engine block heats up and opens water starts to circulate around the block

So to check that you need to fill the radiator with cold water run it for a few minutes check the bottom hose it should be cold

The stat opens and the bottom hose should get hot as the water from the block is pumped into the radiator for cooling.

The radiator should get hot all over and the cooling fan should kick in when the sensor hits the over limit stop.

If that does not happen then get someone to remove the stat altogether (It is only there to get the engine block warm quickly in cold regions )

In which case the bottom hose should go from cold to warm to hot
