Question about Dodge Grand Caravan
I am losing coolant. No noticeable leaks. I was topping it off the other day and wanted to watch for flow. I looked over and the coolant was pushing up over the radiator fill neck and on to the ground. I continued to watch as it went down and then pushed up again pushing more coolant out on to the ground. Is this normal? If not, how do I stop it?
This sounds like you either have alot of air in your system or you head gasket is bad. Get a fluid test and see if here are hydrocarbons present in your coolant. I would say bad head gasket.

You may need to ask AAA to put a radiator pressure tester on the resevoir bottle and pump it up to operating pressure(Pressure cap rating) and see if it over pressurises while it is running at operating temp,rev engine up and down and watch what the testers pressure readings do,it should move up and down in sync with the water pump.If the pressure keeps building i would have to believe that combustion chamber gases are over pressurising your cooling system.Also test the pressure cap is functioning within factory specs.

Hello Ranger Joe, eight months and two radiators is very uncommon. Question, Have you visually confirmed the leak in the radiators or is the leak near the hose connections? Replacing the radiator, cap, water pump, & the thermostat leaves only two others, the hoses and the engine block/heads. Far fitched will be something or somebody poking holes in the radiator.

you must drain air out of system
so when engine is warmed up, just unscrew slightly the thermo time switch which is the highest sensor and unit in cooling system besides the reservoir, until alittle air releases then when antifreeze starts coming out then retighten to specs. BE VERY CAREFUL !!!! LOOSEN VERY SLOWLY AND NOT COMPLETELY REMOVE FOR THIS CAN CAUSE BURNS. MIGHT WANT TO USE A RAG AROUND SENSOR. If this doesnt solve it then make sure you have the correct rad. cap. Also that the filling hose is not clogged as well as the little port on radiator.

Check the oil, is the oil milky on the dipstick?
Check the Transmission Fliud level, Low?
If it is engine oil it could be a head gasket, if it is transmission oil then the cooling lines in the lower tank of the radiator may be leaking.
