I'm winterizing my '99 Merc 3.0L w/Alpha 1 for the first time. I do not have the original owners manual for direction on how best to drain the seawater from it and would appreciate some advice to make sure its done right. I have located the plug on the bottom of the exhaust manifold as well as the one below it on the side of the block. Also disconnected the hoses at the water pump. Some references I find say there is another plug on the block, but if there is one I cannot see it. Any advice from a seasoned veteran familiar with this engine would be appreciated.
Also finding conflicting advice on whether to simply pull the plugs and drain the seawater or drain and refill with the pink antifreeze. Is it necessary, and if so which hole do I dump the pink stuff in?
Thanks
