Notice to Builders and Service Dealers
Generation V Engine Coolant Filling Procedure for the following GM engines:
Kodiak GM 4.3L DI
Kodiak GM 5.3L DI
Kodiak GM 6.2L DI
A heat exchanger and engine block coolant fill and air lock removal tool is necessary
and must be used to purge the air lock from the new Generation V GM engines during
filling or the refilling of coolant.
Procedure for filling or refilling the closed coolant system:
To fill or re-fill the engine and heat exchanger with coolant, you must be sure the
coolant system is leak free at all hose and fitting locations. The filling
with coolant
and purging of air from the engine is done with vacuum rather than by pressure. If
there is a leak present in the plumbing of the closed coolant system, the applied
vacuum will not pull the coolant into the engine. Use the detailed instructions that
came with the fill kit for the filling and purging of the coolant system.
Failure to fill the engine properly with a coolant air evacuation kit may void
all warranty.
Below is a list of easy to use air evacuation purge kits that can be purchased at your
local auto parts store. There are also many of these kits listed on the internet.
It will be up to the builder/dealer to choose the kit of choice for this procedure.
