AC repair Ford Explorer
My friend Ed stopped by yesterday to borrow my vacuum pump. He said his AC was not working on his Ford Explorer. Since he had already picked up some Freon, I decided to just check it out with him rather than loaning out my pump.
A quick check with gauges showed that there was very little pressure in the system. There had to be a leak somewhere. A quick pass with my Freon detector indicated a leak at the low pressure port. This is a very common leak point. We pulled the Schrader valve core and I noticed it looked more like one from a tire than for an AC system. The bottom seal was very ragged and it was surprising it held any pressure at all.
I dug through my parts drawer and found a couple of new cores. We replaced both the high and low ones just to be safe. Next, we put the vacuum pump on and chatted a while.
I shut off the pump and watched the gauges. It held vacuum, so we added Freon to get the right pressure. He had nice cold air when we were done. It has been very hot and humid the last few days here in east Tennessee so I am sure he will enjoy the new cold air.
