The 6976 Cooling System Refilling Gun can eliminate airlocks during cooling system refilling and eliminates the need for system bleeding
Small and large rubber cones suit both passenger and commercial vehicles with no additional adapters needed
Attach the Cooling System Refilling Gun to your shop air supply then insert the nozzle into the cooling system, like the opening on a radiator and establish vacuum
Insert hose into your new coolant reservoir and switch device to vacuum
It will pull air out of the coolant system while new coolant is added
