The fan is usually meant to cool the radiator. It shouldn't be anything to worry about. Since the radiator cools the antifreeze that has come from and circulates through the engine, as long as the fan is running, the coolant is remaining at a good temperature and you won't have to worry about overheating.
A 2012 Dodge Caravan would have the 3.6L V6. That engine has a timing chain which does not require replacement unless worn.
If i wanted to change my transmission fluid in my 2001 dodge grand caravan with a 3.3 liter engine, how many quarts would it take?
I would really like some pictures if possible.
It would be in the Power Distribution Center under the hood, usually on the driver's side.
No, the bell housing patterns are different.
If same size engine, then yes.
when my dodge stratus started to do that it was because I needed transmission fluid.
Low coolant? Cooling system airbound?
we would need an bit more info? engine 4cyl, 6cyl? 2wd 4wd?
The only light that could come on would be the check engine light.
It is never a good idea to remove the thermostat especially on a fuel injected engine. The computer relies on it to heat the engine so it will not run rich. The cooling fans can not work as they depend on the engine to warm up. Check the coolant in the radiator because it can be low and you still have water in the recovery jug. You may have a bad radiator or cooling fans. There is a TSB with Dodge relating to the fan controller. It is located behind the front bumper.
It would be very rare for a P1684 code to turn the light on.
