Precautions
This equipment is designed for servicing a variety of vehicles
in a safe, convenient manner. However, differences in cooling sys-
tems may make it impossible to perform some of the tests indicated in
these instructions on every vehicle.
The procedures documented in this manual are to serve as guidelines
for the use of this equipment. In addition to these guidelines, always
follow the manufacturer’s recommended procedures when servicing
each unique vehicle. Do not attempt to force a test
on a cooling system for which this equipment is not designed
to perform.
Performing cooling system tests using the MV4533 is simple and
straightforward if you follow the instructions. However, always keep in
mind that you are working with a system that may be full of cold or hot
fluid that is under pressure and just waiting to be expelled.
Always read carefully and understand instructions prior to using this
equipment.
Always wear eye protection when removing radiator or coolant bottle
cap, or when performing any cooling system test.
Always allow system to cool prior to attempting to perform any cooling
system related test procedure.

Notice
Some late-model vehicles are equipped with radiator tanks
and expansion tanks made of plastic. Excessive over-tighte-
ning of the expansion plug could result in cracking of the radiator
or expansion tank. Use caution when tightening expandable rubber
plug.
Always refer to the manufacturer’s instructions for the particular
radiator pressure tester that is being used.
