Winterizing Question- Looking for Ideas
I thought I had the perfect way to winterize my 500 EFI's. I use the bottom half of a 275 gal.tote. On the first engine I start by dumping 12 gal. of -100 degree anti freeze ( 6gal from last year and 6 gal new ) in the tote. I hook a pump up to a muff and circulate the antifreeze thru the running engine until the temp gets to over 150 and I'm sure that the thermostat has opened. I then fog with MM oil and shut it down. I then un-hook and move the tote and pump to the second engine, add 6 more gal. of new antifreeze and start the process over again.
Now here is my problem : I can get the second engine up to 150 fairly quickly since the antifreeze is still hot. For the second year the 2nd engine will start to miss and die before I can get it fogged. It will not restart. The only think I can think is happening is the hot antifreeze is effecting the fuel delivery like a Vapor Lock or it is effecting the cool fuel system some way. I would bet once it cools down every thing will be fine.
Does any body else have any other thoughts ?

Interesting. Yeh, your probably turning the Cool Fuel heat exhanger into a Hot Vapor Maker.
On a side note: what kind of pump are you feeding the antifreeze to the muffs with ?

I drain the water (closed cooling) from headers and cool fuel, power steering, reinstall plugs and with muffs in place while hooked to elevated bucket full of pink stuff. Run 4 gallons thru, shut off and drain again to ensure room for expansion just in case

When you drain the block will water left in your circulating pump still drain?

Thanks I wasn't thinking looks like my weekend project.
