I took my 2004 Ford Ranger XLT (4.0 SOHC) into the local Midas shop to have my oil changed. They noticed that radiator fluid was beginning to seep out the water pump pulley seal and recommended that I replace the pump before there is a failure. I had the shop replace the water pump. I also requested that they check the A/C system to ensure it was in good shape. There was nothing wrong with it, I simply wanted to be proactive. This was 6/19/2014. I was told that I needed a recharge of the A/C system. I live in Seattle where you need A/C only 3 days out of the year. I let it slide. The pressure readings were 30psi/180psi/45degrees
This past Saturday, I purchased an A/C recharge kit because my A/C does not blow cold air, and hasn’t since about the time I had it checked.The low pressure port is at 100 PSI! Also, the clutch does not engage on the A/C pump. I tried charging the system with just a couple shots from the recharge can but no luck in getting the clutch to engage.So, I used a bicycle wheel spoke to let some pressure out of the low pressure port and I noticed green radiator fluid collecting on the spoke. Is this normal? My radiator fluid is straw yellow (color of a dehydrated person’s urine). I believe the radiator fluid was green before the pump replacement.
The A/C worked beautifully before the water pump replacement. Did the shop mess something up? I wrote a very ugly review in Yelp and they wish to verify my issue. I reacted emotionally without any technical facts and wish to verify the technical probabilities before responding to the shop. Given the relationship between the engine coolant system and A/C system, something is not right and I believe they sabotaged the A/C system for repeat business. Thoughts?!
