Warning: Antifreeze is a corrosive and poisonous solution, so be careful
not to spill any of the coolant mixture on the vehicle's paint or your
skin. If this happens, rinse immediately with plenty of clean water. Con-
sult local authorities regarding proper disposal procedures for antifreeze
before draining the cooling system. In many areas, reclamation centers
have been established to collect used oil and coolant mixtures.
1 Periodically, the cooling system should be drained, flushed and
refilled to replenish the antifreeze mixture and prevent formation of
rust and corrosion, which can impair the oerformance of the coolinq
system and cause engine damage. when' the cooling system is ser-
viced, all hoses and the radiator cap should be checked and replaced
if necessary.
2 Apply the parking brake and block the wheels. If the vehicle has
just been driven, wait several hours to allow the engine to cool down
before beginning this procedure.
On models other than Wagoneer, first check the
bottom of the radiator for the drain fitting
