Vacuum Fill Coolant Tool, Test Radiator and Heating Core Lines for Leaks, OEMTOOLS 24444 Coolant System Refiller Kit, 5 Adapters, Eliminate Trapped Air, Vacuum Leak Tester

#ad
OEMTOOLS #ad - Easy complete coolant system refiller: Refills the entire cooling system including the Heater Core. Discover leaks: it’s easy to check for leaks while under vacuum; if your vacuum level decreases while all valves are off, you have a leak in your system.

Widely useful: comes with five adapters that fit most common radiator necks and coolant reservoirs. Simple to use: all you need to use this coolant system vacuum kit is a shop air compressor; The included venturi valve turns any air compressor input into a strong vacuum force. Huge time saver: eliminate time consuming bleeding and purging, and completely remove all trapped air from your cooling system; Removing air through a radiator burp is much more time intensive.
