I am not sure. I never tried to remove the dipstick. I just think it is a float to mark the fluid level inside the expansion tank since you can not see thru the tank housing.
So... checking the coolant level when the engine is cold. The float should be flush(atleast, or higher) with the top of the expansion tank threads.
IF the dip stick float is sitting lower than the top of teh threads... your coolant is too low. Atleast that is teh way it looks like it works to me. lol
Maybe I should go look at my float tomorrow morning before I fire up the engine.
