Reply to ""Secret" screen in AC line at Evaporator Core..."

bosswrenchMember

The conical filter is in the side (horizontal leg of the expansion valve, not in the port going to the under-dash evaporator. It is approx. 1/4" OD x 3/4" long, pointed at the far end. To remove, hook it out with a scribe & soak in some paint thinner or other solvent to soften rubber flecks. While both or my AC units had this screen in (a '72 & a 73), it may not be universal. One of the vendors told me they remove it for R-134a conversions because the crummy AC characteristics of this freon needs higher flow.
