Mityvac MV4560 COOLING SYSTEM TEST KIT - Manual (Page 5)

Form 801625 Page Number - 5
When testing a used cap, consider that the seal
may have retained an impression left by the seat
of the filler neck. Remove, re-assemble and
retest the cap several times if necessary before
rejecting the cap for a leak. When testing a
new cap, consider that the seal is new and has
never been softened by heat. Some breaking-in
of the seal may be necessary to prevent it from
leaking.
Adapters
The MV4560 includes four cooling system test
adapters that fit the radiators and coolant bottles
on the vast majority of US and Asian manufac-
tured vehicles, and even some European vehicles.
An adapter is required to connect the test equip-
ment to the cooling system of the specific make
and model being tested. Once the correct adapter
is identified for the vehicle being serviced, it can
be used to perform all of the cooling system tests
outlined in this manual.
The MV4560 also contains two adapters for test-
ing radiator or coolant bottle caps. Each end of
the two adapters is matched to one of the four
system adapters, and is designed to test the cap
for that system.
