Q: How to replace the evaporator on 2000-2011 Ford Ranger?
A: On 2001 and later models, the evaporator is serviced as an assembly with the evaporator housing. It is not available individually. The accumulator should be replaced whenever the evaporator is replaced. Start by having the air conditioning system discharged. Then, disconnect the cable from the negative terminal of the battery. On 2011 models, remove the air filter housing duct. Remove the accumulator. Remove the fasteners to the vacuum reservoir tank and bracket and set them aside (if equipped). Move the cruise control servo aside by disconnecting the electrical connector and removing the mounting screw (if equipped). On 2001 and later 2.3L engines, remove the air conditioning compressor. On 3.0L and 4.0L V6 engines, remove the coolant and windshield washer reservoirs mounted together. Disconnect the Blower Motor and blower motor resistor electrical connectors. On 2001 and later engines, disconnect the heater hoses from the heater core tubes. Move the window washer hose and small hose retainer aside. Disconnect the heater control vacuum hose from the vacuum control valve (in-line with one of the heater hoses). Disconnect the refrigerant line from the evaporator to the condenser using a spring lock coupling tool. Cap the lines to prevent entry of dirt and moisture. On 3.0L and 4.0L V6 engines, remove the hose bracket from the top of the A/C evaporator housing. On 4.0L V6 engines, remove the hose bracket mounted on the rear of the engine. Remove all fasteners to the evaporator housing, noting that some may exist inside the passenger compartment at the firewall. On 2001 and later models, disconnect the vacuum hose connector from inside the passenger compartment. Remove the evaporator housing. On 2000 models, remove the core. Installation is the reverse of removal with the following additions: Replace all O-rings with new ones specifically made for air conditioning system use. Lubricate them with special PAG refrigerant oil designed for use in R-134a systems. Use mineral oil on R-12 systems. Do not use the wrong lubricant or you may contaminate the system. Have the system evacuated, recharged, and leak tested by the shop that discharged it.
