I don't know where to start, I can't even see how the fan comes off. Just need to know generally how to loosen and tighten them back up. I can see myself ending up with squeaky belts here.
I am a very detailed person, for example I didn't know that the bottom half circle of the fan shroud unclips. I actually undid the screws holding the shroud to the radiator before removing it
Also, how do I turn the engine to BTDC?
