Adding Coolant
If you
need more coolant, add the proper mix at the
coolant recovery tank.
Add coolant mix at the recovery tank, but be careful not

'hrning the radiator pressure cap when the
engine and radiator are hot can allow steam and
scalding liquids to blow out and burn you badly.
With the coolant recovery tank, you will almost
never have to add coolant at the radiator.
Never turn the radiator pressure cap
