I don't think you would have to go to that extent with this truck. The passenger side valve cover needs to come off and I'm almost positive the magnet is right there. However, the cooling system needs to be evacuated. According to EPA regulations, I can't do that on my own. I realize that because of where I live, I could do that and get away with it, but I don't wanna. It's not worth the risk.
I have a strong feeling the truck will be dropped off at your shop soon.
I'll let you know if that's the case. I'll help you push it into the shop since it can't be driven in.
