Question about 2001 Dodge Grand Caravan

1 Answer

Leaking coolant I have a 2001 Dodge Grand Caravan 3.3L Flex Fuel engine. When engine temp gauge is about in the middle there is a coolant leak. The temp skyrockets from then to the redline in the matter of 1 minute. It seems like it's coming from the other side of the thermostat housing (underneath the spark plug hub; i.e. the other end of spark plug wires). The coolant level in the bin is leveled off. It does not look like it's lowering. I looked inside the radiator as well and i can see the coolant but all the way at the bottom of the radiator (not sure how much should be in there). I also did the feel test for the return hoses and they feel warm. Can someone let me know if they had the same problem or what should I try? Thanks.

The coolant should be right at the top of the radiator if you can see the bottom of the radiator that you have a stuck thermostat

    also you will have to fill the radiator and the bottle if you have to change the thermostst

    you should not have to some will drain out of the thermostat housing when you change that...after you change it you will fill the radiator and then start the engine with the cover off the radiator and when it gets warm and starts to go down just continue to add fluid until it does not go down and then replace the cover ...the car needs to be up to temp. before it is full

Are you sure that it is coolant. Puddles form under vehicles where the AC drain is under the car. Check that the puddle is actually coolant and not water from the ac evaporator core.

Dodge grand Caravan 1995 has been acting up with erratic heating since last month.

Could possibly need a new thermostat, the thermostat opens and closes depending on the heat of the coolant. maybe also check your heating core. as well as the quality of you coolant.
