
Clean the intercooler, air and coolant
side (if equipped)

Air Side.
To clean the fins, immerse the
stack in a tank containing a
degreaser solution. It is most
effective when used as close to
boiling point as possible. Either
steam or electric immersion
heaters may be used to heat the
water. If the degreaser used is in
powder form, then the powder
should be added to the boiling
water (never vice versa). Agitation
of the solution, either by raising or
lowering the stack or by means of
a jet of steam or air may accelerate
the washing process.

Coolant Side.
To clean the tubes internally if the
scale is hard and too stubborn to
remove with wire brushes we
recommend removal by dipping in
and acid solution.

Clean the intercooler (if equipped)

Remove the cooler from the engine
and strip down so that the stack
can be immersed in a cleaning
tank. When the branch and return
headers are removed, the stack
comprising tube plates, side plates
and cooler sections can be
immersed first to clean the fins and
secondly to descale the tubes.
