Question about 2009 Dodge Grand Caravan
I've recently had my hoses and thermostat replaced in my 2009 Dodge Grand Caravan, and also had a total flush of the system. However my van keeps setting off my check engine light and my temperature gauge keeps going off. I took it into my mechanic, and they hooked all of their instruments up to the van and even though all gauges show its over heating in the van its self, the over all temperature according to my mechanic stayed around 220 degrees. He said even though this is a little elevated, it is by no means over heating. Basically everything has been replaced except the radiator...but now we are all lost! Does anyone have any suggestions?
Have you checked the electric fan/fans on the radiator? It may also pay to check the sender sensor which starts and stops the fan/fans.This may sound a bit silly but is the rad.cap correct pressure setting and is the pipe to the expansion tank clear?...Maybe of some help.

What engine does your Ram have? This could be an indicator of a bad head gasket. If the sensor for the gauge is truly bad, the only way test that theory is to install an aftermarket gauge, use an infrared temp sensor on the water outlet hose or replace the coolant temperature sensor. If this doesn't help, you may need to take it to a mechanic and have them do a leakdown test. Failed headgasket can cause bizarre overheating issues. Good luck.

Hello, as previously suggested by my collegue it appears you have an air lock. Have you tried parking the vehicle on level ground, from cold with radiator cap off start the car and leave it idling. Make sure the fluid/coolant levels are o.k. and let the engine reach operating temp. Keep some warm water handy and watch/listen the water/coolant system (Keep a safe/sensible distance from radiator) hopefully after a while the system will bubble and boil up let it settle for a few seconds and then top up with very warm water do this until it hopefully stops belching out of radiator. Replace cap and hopefully top and bottom hoses will be warm. Oh! nearly forgot keep all heater controls on hot with blower on full..(Inside the vehicle)
Finally I'm not joshing but is the thermostat in the right way round and functioning correctly? to test drop it in some boiling water it should open almost immeadiatly.
sorry for the epic but I'm here to help and hopefully save you time and money.
Good luck and a Happy New Year to you and your family!

Replace the bad radiator hose first. Second- get you special formulated anti-freeze dye from the auto store and pour it into the radiator. Third- make sure you got all the air pockets out of your system, cause the coolant system won't work with air pockets in it. Fourth- Check for leaks by looking for the colored dye. If it's not the radiator hose, then could possibly be a pin hole in your radiator. Would suggest replacing all the radiator hoses at the same time while you got the coolant system disconnected, cause you don't want to have to come back and replace another hose in a few months.

The EVAP System has a leak and needs to be repaired.
Obviously your mechanic,has not kept up with todays vehicles. EVAP issues are common. I would get a new mechanic, and make sure they have an EVAP Smoke Machine,otherwise their wasting their time and yours.
Also,if your the type of person who rides around 2 years with a check light on,you don't have much interest in what you drive.
I would guess you got at least one other drivabilty issue.
Pull the codes,and have your NEW Mechanic repair properly and SOON

If it is fogging your windows, you have a leaking heater core. Dash removal is required to fix it.
