Taurus V6-195 3.2L DOHC SHO (1994)
Service Port HVAC: Description and Operation
CAUTION: Do not use R-12 special tools and equipment when servicing a R-134a system. This may cause damage to the R-134a A/C system.
The high-side fitting is the largest and special couplings are required to connect service equipment to both the high-side and low-side service ports.
^ Quick disconnects must be used to connect a manifold gauge set to the system.
^ Rotunda R-134a Low-Side Quick Disconnect 176-R0036 or equivalent is the low-side quick disconnect and Rotunda R-134a High-Side Quick
Disconnect 176-R0037 or equivalent is the high-side quick disconnect.
^ Always install the A/C charging valve cap (19D702) on the service access gauge port valves after servicing the refrigerant system.
The service gauge port valves are either a one-piece or two-piece design:
^ In the two-piece design, the aluminum top portion of the valve is threaded to the bottom port and sealed with an 0-ring seal. The valve seal is an
integral part of the aluminum fitting piece which must be replaced if the seal leaks.
