Mityvac oers the most advanced cooling system test and rell equipment available. In addition to oering a professional pressure tester
and AirEvac kit, Mityvac is the rst to combine pressure, temperature, and vacuum testing and automatic rell into one kit. Only MV4525
is capable of performing all these tests and functions, replacing up to three dierent competitive kits. But even more important, it is the
rst tester designed for testing a vehicle with the engine on or o. Testing with the engine on provides real-time feedback of pressure,
vacuum and temperature while the engine warms up through its normal operating cycle, providing the most accurate assessment on
how the cooling system is functioning. Using this system, a technician can quickly and easily diagnose cooling system leaks, a blown
head gasket, a cracked or damaged head or block, or a faulty thermostat, fan switch/relay, or coolant sensor.
To compliment our testers, Mityvac oers 29 custom designed adapters to t the radiators, coolant bottles, and caps of virtually every
make and model of US, Asian, and European manufactured car and light truck. All adapters are sold separately, and are also available
in ve cost saving kits.
The MV4525 is the most innovative, advanced automotive cooling system test kit ever
designed. It is the rst and only tester developed specically to run complete cooling system
diagnostics with the engine running and at normal operating temperature and pressure.
New patent pending technology combines testing and monitoring of pressure, vacuum and
temperature simultaneously, to provide real-time data far beyond the capabilities of a simple
pressure tester. This combination of features ensures the most extensive, accurate cooling
system diagnosis possible. See pages 40 and 41 for a complete list of available adapters
and their applications as well as convenient, cost saving adapter kits. Visit mityvac.com to

Applications:
• Pressure and/or vacuum test for leaks in automotive cooling systems
• Rapidly rell cooling systems without trapping air
• Check proper function of thermostat, cooling sensor, and cooling fan(s)
• Diagnose blown head gasket(s), cracked block, and cylinder head damage
• Cooling system cap pressure testing (additional adapters required)
Features:
• Patent pending coupler saves the expense of
up to three separate kits by combining pressure,
vacuum and temperature testing capabilities
• Tests cooling system with engine on or o to
pinpoint leaks or diagnose blown head gaskets,
cracked block, or damaged head(s).
• Rells cooling system in minutes without
trapping air that can cause overheating
• Components connect using self-locking
quick-disconnects for easy and time saving
assembly and breakdown.
• Safety valves prevent discharge of pressure and/
or hot uid in case of accidental disconnect
• Built-in valve allows the rapid, safe release of
pressure and uid without waiting for the system
to cool
• Includes four adapters for connecting to the most
common radiator and coolant bottle necks found
on Domestic, Asian, and European
automobiles.
• Additional adapters available for all makes and
models of cars and light trucks
