How to Add Coolant to the
Cooling System
Notice: The engine has a specific cooling system
drain and fill procedure. Failure to follow this
procedure could cause the engine to overheat and
be severely damaged. If the engine’s cooling system
needs to be drained and re-filled, please see the
dealer/retailer.
If no problem is found, but the coolant level in the
coolant recovery tank is below the COLD FILL line,
add a 50/50 mixture of clean, drinkable water and
DEX-COOL

engine coolant at the coolant recovery
tank. See Engine Coolant on page 5-24 for more
information.

coolant at the pressure cap as follows:

CAUTION:
Steam and scalding liquids from a hot cooling
system can blow out and burn you badly.
They are under pressure, and if you turn the
pressure cap — even a little — they can come
out at high speed. Never turn the cap when the
cooling system, including the pressure cap, is
hot. Wait for the cooling system and pressure
cap to cool if you ever have to turn the
pressure cap.
