We have a 2008 Dodge Grand Caravan. My question is: when the engine is running, does the radiator fan run constantly or intermittently?


electric fans start to operate when the coolant temp reaches around 88 c and will run continuously while the coolant is above that temp
if you have ac then there is a fan that cools the condenser in front of the radiator and that will cycle according to the ac compressor cycles

My 2006 Caravan temperature gauge goes to red - engine is not overheating. Kick it into a lower gear (automatic trans) and the gauge comes back down. Is it likely the coolant sensor?


Could be.. is the system FULL? Air in it can cause some odd things. When engine and coolant are COLD (as in after sitting over night), open the radiator cap. Top off the overflow res with a 50/50 antifreeze / water mixture to HOT mark. Start engine, turn heat to hot and fan to high. Top off RADIATOR with same 50/50 mixture slowly & gradually. As the coolant circulates, it should bring any AIR trapped in the system (from heater core & engine block) to the radiator where you can replace it with the 50/50 mix. Once the coolant is HOT and stays level - about an inch under the opening, close the radiator. Monitor the overflow res and add as needed. Good luck!

I have a 02 Grand caravan that has new radiator, termostat, one new fan. the temp gauge goes up to max hot the drops right back down in seconds. what could be the problem?


it could be you have an air lock in the cooling system
remove the rad cap from the rad, start the engine and let it run until the coolant drops (add to fill it back up) or until the coolant boils out of the rad spout.

maybe pull the heat sensor. -replace it OR clean it off, reinstall it.

Electric cooling fans will work.


The fans are actuated by coolant temp in the radiator. It is possible to have overheated coolant in the radiator, causing the steam, and your engine not overheating...the temp sensor for your engine is reflecting the engine temp, not the temp of the coolant in the radiator. You problem could be a bad temp sensor at the radiator...not allowing the fans to come on. Good Luck! I hope you find this to be very helpful!
