Matco Tools | MPT333 Cooling System Pressure Tester, Refiller and Retainer

[@chriscoleman3189]

For the pressure yest feature. Is there a regulator to make sure you are not over pressurizing the cooling system?? Or pressure relif valve

[@LisaMiller-mf2eg]

Yes. The tester head has a 30lb. blow off spring so you can't over pressurize.

Hello, does the tool come with an instruction manual for the various position of the valves for the 3 separate functions?

[@LisaMiller-mf2eg]

Yes!
