I am going to be changing the coolant on my 94 Accord EX (F22B1) and I pretty much know what to do when changing the coolant but this is going to be my first time changing coolant. Some of the things I'm wondering is getting at the air bleeder bolt. Its in a hard to reach spot and I'm pretty sure I have to move some stuff out the way like the little hoses and maybe the egr electrical connector. I'm wondering what is the easiest way to get to this bolt? Also in my haynes manual it says to put non hardening sealant on the threads of the coolant drain plug on the block. I'm wondering do I do this for the radiator drain plug also?
