5. Fill the coolant recovery tank to
the FULL COLD mark.
6. Reinstall the cap on the coolant
recovery tank but leave the
radiator pressure cap off.
7. Start the engine and let it run
until the upper radiator hose
feels warm. Any time during
this procedure, watch out for
the engine cooling fans.
8. If the coolant level inside the
radiator filler neck is low, add
more of the proper DEX-COOL
coolant mixture through the filler
neck until the level is back up to
the base of the filler neck.
9. Replace the pressure cap.
Be sure to secure it tightly.
At any time during this
procedure if coolant begins
to flow out of the filler neck,
reinstall the pressure cap.
Notice: If the pressure cap is not
tightly installed, coolant loss and
possible engine damage may
occur. Be sure the cap is properly
and tightly secured.
