is there a drain plug at the bottom of the radiator to drain it ?(if not, how do you drain it?) do you add fresh anti-freez mix to the plastic reservoir? ( since you can no longer access radiators directly)
All help appreciated —
After you place a catch container under the radiator, and disconnect the large hose from the bottom of the radiator, most of the old coolant will pour out. Yes, pour the fresh coolant mix into the reservoir.
I have a '97 F150 with the 4.6L engine. It also has a drain plug on the engine block on the drivers side. Service manual indicates there should be one on the passenger side as well, but I never found it. As hellokit says, just add the coolant to the reservoir.
