GMT400 Suburban Frame Off Build: Body Removal & Getting Ready for Frame Paint! (What To Remove)
What happens here
The creator initially thought the AC and heater lines would need to be disconnected by releasing them from the body, but upon closer inspection, he realizes they have quick-disconnect fittings behind rubber boots near the frame rail. He uses a screwdriver to push the internal collar, along with some WD-40, to release the lines, which results in a significant coolant leak. He then collects the leaking coolant in a bucket. He mentions using two wrenches for the remaining connections.
Goal: Detach AC and heater lines from the body for removal
