Well, I am not the sharpest tack in the pail, but I am confused........
I drained about 5 quarts of coolant from the drain plug.
I removed the lower hose and got nothing.
The overflow tank is empty.
I briefly ran the engine to see if any additional pumped out. Nope.
I am supposed to see a replacement volume of about 14.75 quarts. Drained only 5 quarts.
(Note: My drain plug now works after draining the radiator and blowing 20 psi into the drain plug hole.)
Since I am replacing the Chrysler HOAT with another HOAT, I would like to get all the old coolant out. So will flush the system a couple of times (one gallon drained per time).
On my Cummins C8.3L I get 25 gallons with no effort at all so I think I know the procedure.
Why am I only draining 1 gallon at a time instead of about 3 gallons?
