Question on winterizing a 330 Excal

[F725]

A buddy of mine has a 2003 SAN 210. He had a friend help him winterize it but he said he only drained one side of the block. The other side (port side) they did not drain. In all my years of winterizing boats, I've always drained both sides of the block. He did drain the exhaust manifolds, the water pump, strainer, etc... He didn't drain the v-drive either... I helped him do that last night. Can you tell me if he needs to pull the plug from both sides? Thx.

Yes, both sides need to be drained. The knock sensor is the drain on port side, regular plug on starboard side. V-drive has two drain plugs, tranny cooler has one.

This is an excellent guide to follow. Please be sure to read the additional posts after the OP.

Sounds like his lac of knowledge is going to cost him an engine. Almost winterized is like a little pregnant.

When I bought my 86', the first few years I would drain the block and manifolds then run the RV AF through. around 4 gallons or so. Then I realized I was wasting time draining the water first. I now simply run 4 - 5 gallons of RV AF through and never had a problem in 10 or so years. The AF flush is replacing all the water so why bother draining it? And the winters get pretty frigid in Pittsburgh.

You are "probably" safe with that method however I would not recommend it. There is risk in diluting the A/F, particularly when using the pink RV stuff, and if the TStat is closed the water in the block will be restricted from exiting.

So for any new winterizers, "BEWARE OF THE ABOVE ADVICE".

I went the other direction. I drain by hand, and from here on out am skipping the pink rv antifreeze. That way I can get up close and personal with engine once a year to check things out, and save $ and effort with rv antifreeze, and worry that it might not get everywhere in semi warmed up engine. Manual even states to drain first and then use antifreeze as an additional option.

Also that link shows teflon tape being used on knock sensors. I thought people on this site said that was a "no no"?

I like the thought of my impeller, hoses and other rubber seals and parts bathing in AF while in storage. That would be my only issue with this plan.

Thanks guys! I could've probably talked him into draining the knock sensor side but just wanted to make sure that it was a necessary thing to get done. He'll be stopping over this afternoon to have me give him a hand.
