Review on EVAP CORE ASSY NEW EVAPORATOR by Darius Early

Classic or Antique Truck Restoration. Look no further, this item works perfectly. This is an excellent quality item. I installed it on my 91 F150 with no further complications or problems. This is pretty much the original R-12 system so you need to do an R134 conversion where you only have one pressure valve to get the system to work on the low pressure line. This is normal but may not work in a hot environment. So I recommend you to put a second pressure sensor in the high pressure line and you won't regret it. (Items needed: Four Seasons Wiring Harness Connector 37219 and Four Seasons Dual Pressure Switch 36646 installed in the system. This is required to shut down the system if the high pressure is above 250).
