CAUTION

To prevent property damage, if the coolant should

get extremely low and the engine very hot, let the
engine cool for approximately 15 minutes before
adding coolant; then, with the engine running,
add coolant slowly. Adding cold coolant to a hot
engine may crack the cylinder head or crankcase.
Never use water alone.

Top-Off Coolant Fill Method

This is a traditional gravity-fill-only method that involves

pouring or pumping the coolant into the deaeration tank of the
cooling system and using a combination of gravity and engine
operation to purge the system of air. This method includes
the disadvantage of a requirement to temporarily disconnect
the EGR wiring harness to protect the EGR from heat damage
prior to being completely deaerated (freed of trapped air). This
process may generate a fault code that might require further Typical International® A26 Cooling System Deaeration Tank
