Update: I went and got my radiator replaced around the 18th of December. The next morning I went outside and started up the truck so it could warm up. After ten minutes or so I went back out and noticed the new radiator leaking from the covers worse then the original. Took it back and was told the cold (-40F) damaged the seals. Now that it is relatively warmer they replaced the bum radiator. The truck still loudly thumps. After getting home I checked underneath the front end and noticed antifreeze on both sides of the replaced radiator, same spots as before though not as bad, antifreeze was on the fan cowl, and there was a faint smell of hot coolant. I wiped everything down and checked this morning and didn't see any spots in the snow or any noticeable drips forming on the parts. I plan on checking later after the truck cools to see if there have been any other leaks.
I talked to a ford dealer and wasn't given much help about the bypass kit. They found the service bulletin, but couldn't find a part, or a description, or schematic. I was told that the thumping was merely an annoyance but wouldn't cause any problems.
I was curious about this thread:
It summary it said that the thumping in his truck was caused by a bad power steering pump that was robbing the water pump of power and causing steam. my question is could the AC compressor cause a similar situation? My compressor clicks (I think this is it engaging and disengaging) and whines heavily. It is just a thought, but I thought I'd ask knowledgeable minds.
Thanks for your continued help.
