Arguments I have read sound like as follows:
a) Use Muffs to bring in af. It's easy to miss a plug, and if you do, you won't fully drain the block and will end up with a cracked block.
b) Drain block and backfill through thermostat housing. It's what Merc recommends, and the muff method just dilutes antifreeze.
I have read a number of things that make me question the effectiveness of both methods. So why not do both?
Suck up antifreeze through the muffs as you fog the engine (with a few ounces of ob oil in the seperator). Once done, drain at the plugs as Merc says, and backfill with af.
It costs an extra $20, and it ensures you will be full of undiluted antifreeze.
Am I missing anything?
Sorry if this starts off a war. I am just trying to figure out the best way to get this done.
