Failed on charging the AC system and finally really drove it for the first time with the V8.
As I mentioned yesterday, we were trying to charge the AC sustem that I thought worked in the explorer before it was disassembled. The rental vacuum pump from O'Reilly wasn't up to par and would only pull around 16" of vacuum. Purchased a much larger (3 vs 1.8 CFM) two stage vacuum pump from harbor freight this morning. That thing works. Pulled the system down to 30 inches almost instantly. Let it run for the recommended two hours. Unfortunately trying to charge it revealed that the compressor isn't working. Compressor clutch works, we jumped it and it engaged, but built no system pressure. Going to take a break and drive the truck for a few weeks before taking it back apart to fic AC. In the mean time I have to decide if I'm going to re-use parts from the previous (working) 4.0L AC system or buy all new Explorer 5.0L components. I just bought the receiver drier and orifice tube so they should be good. Both evaporators should be ok since the orifice filter would catch any debris, just flush it. The compressor and condenser are the questions. Compressor is the same except pulley size is different, but those can be swapped. Condensers mount different, the 5.0 to the radiator and the 4.0 to the core support. If it fits with the 5.0L raiator, the 4.0 condenser would be easier when/if I need to work on the cooling system in the future. I might start another thread on this.
After figuring out the AC was a bust and pulling the compressor relay, I took it for it's second maiden voyage up the interstate. Second because I did drive it up the interstate to the exhaust shop, but still maiden since it wasn't running right due to plug wires being wrong and got towed back. Ran great, but I expect it to get better as the system learns. Hopefully the transmission will learn some too. It shifts well, but I feel like it could be better. Might just have to get a tuner and adjusted shift points after I get a few miles on it. I imagine a shift kit would help as well, but not sure I want to touch the internals on a relatively unknown transmission.
Drove truck home tonight and it will be my daily for the next few days (weeks?) unless something happens. Might take it to my mechanic buddy later this week and complain about the noise and feeling different without mentioning the swap. He doesn;t know I started the swap, but knows me and will figure it out quickly. Also probabaly give me crap for not fixing a few things while I was in there.
