why is my 2010 Town and country overheating

Is your heater blowing hot air? If not, I'd suspect either you have air trapped in the cooling system or the water pump is not working. Either condition will cause the coolant not to circulate and make the engine overheat. Plus since the coolant is not circulating the heater will not blow hot air. Hope that helps! Jim

Yes, if the engine is actually overheating and the radiator isn't hot, the coolant isn't circulation and you likely have a closed thermostat or a dead water pump..... With the engine running at a temperature where the thermostat would be open and the radiator cap off, see if you detect coolant moving. If you see movement in the radiator, the problem might be a defective engine coolant temperature sensor: easy fix.

Maybe the timing is just way off
