Introduction
The 75700 COOL
X
CHANGE offers everything you need to quickly remove and replace coolant in a vehicle:
drain and fill, and pressure test for leaks. Two external, new coolant supply tanks allow on-board storage of
two different coolant types.
No electricity is needed—shop air powers the unit. No hoses to cut. No additional ventilation is required—the
service procedure is performed with the engine off. The coolant transfer process is “hands off”—simply make
the correct connections and watch it happen. A typical exchange procedure may take only 10 minutes!
