Overheat while winterizing

[lenny2113]

I started winterizing this weekend. The canister I had antifreeze in did not have a hole in the went cap. The pump sucked all air out of the can and by the time I noticed this the can was already deformed with the liquid barely comming out. To make things worse I closed the valve on the winterizing system and turned to the gauge... the gauge was showing 220 degrees. I shut the engine off right away and let it cooled off to 160. I restarted and completed the process. <br /><br />What should I look for in terms of possible damages that might have occured as a result?

if u are only talking about a couple of minutes overheat at idle it probably wont have done any damage..<br /><br />trog

Impeller.<br />Throw away the AF winterizing can and do it the old fashioned way, drain, and backfill with AF if you want to use AF. That's what I do and I find it easier and less stressful.<br />I took that West Marine winterizing tank and turned it into a flusher for my trailer brakes and also to winterize my pressure washer! Added a 700 GPH livewell pump and it works great. I dont like the run the AF thru method because you never know if the thermo is fully open, if not you will have a block full of water and manfolds full of AF. Then you have to drain the block anyway.

Throw away the AF winterizing can and do it the old fashioned way,

Ayuh,...............<br /><br />Drain It,....... Drain ALL the Water from the System,.........<br /><br />And,........ Quit WA$TING Your Money on Antifreeze.......................

Re: Overheat while winterizing

Lenny,there are a few things that you MUST do while using the kit to winterize.1 is to have the jug in your sight to monitor the AF as the level decreases and 2 is to have the temp gage where you can glance at it the entire time.To have someone watch one of the two makes it a lot easier.If you had your eye one either one of these,you would not have had a problem.The temp will usually rise when you switch over from water to AF but it is supposed to.Thats what makes sure the stat is open.I know I am in the minority here about using the kit but for me it is the only way to go.AS LONG AS you are careful about watching the gage and monitoring the AF level.What I cant understand is ,IF you filled the jug with 5 gals of 50/50 or other af,the af should have leaked out the vent hole when you placed the jug on its side to use it.OR did you mean you forgot to remove the cap from the vent?? Either way you will need to replace the impeller.I doubt any damage to the motor occured being that fwc motors run close to 200 degrees anyway.Charlie

Amen, Bondo. <br /><br /><br />The money, pollution and wondering if your got the anti freeze everywhere. Why !!!!!!!!!I just don't get it.

Re: Overheat while winterizing

As a first timer at winterizing I have to agree with the drain it and leave it approach. I bought 5 gallons of antifreeze ($20) warmed the engine to operation temp, sucked the antifreeze through the muffs and shut down when it was gone. Just to be sure (and I'm gald I did) I took out one of the engine drain plugs and nothing but water came out. I then drained the engine (as instructed in the manual) and there was no antifreeze anywhere except the main intake. So I spent $20 and a lot of time to learn that the t-stat may not open or stay open when you run the antifreeze in. Just Drain It and be safe!!!

Re: Overheat while winterizing

useing antifreeze is a good idea if u have big tank of the pre-mixed stuff like a marina has.. <br /><br />silly idea if u only have a bucket full..<br /><br />trog

Re: Overheat while winterizing

Guys, Thanks for your replies. I will actually drain block, just to be on the safe side. Then I thought about pooring AF into the hose that is coming out of the water circulating pump. <br /><br />Charlie, <br />I got a brand new winterizing kit by "Camco" and when I filled it with AF, I removed the vent cap, but did notice that there is no hole in the vent ... When I saw the bucket loosing air and deforming, I shut off the AF release valve first , and 10 seconds later shut the engine off. I punched a hole in the vent and resumed my winterizing process. Second engine winterizing went without any problems. <br /><br />I will still drain the block. Better be safe then sorry. <br /><br />Thanks again for suggestions and reassurance. <br />Lucky you, all warm climate boaters, don't have to deal with all this B*S*

Re: Overheat while winterizing

Len,I would open the block drain a little and if AF comes out ,leave it in.If water comes out then drain it.The camco kit has worked for me for a long time and many winterizations.The directions in the kit suggest to remove the stat before starting the job.I dont.I keep the af in my boiler room so it is not cold and I mix it with warm to hot water.This assures me the temp will rise while the af runs through the motor keeping the stat open.Glad to hear the second go round went well.Charlie

Re: Overheat while winterizing

I'm using antifreeze for the first time this year, as I want to launch and fish off and on throughout the winter. I just ran the engine on muffs until the thermostat was open, then used a 5 gal bucket of 50:50 poured into a funnel attached to hose going to muffs. After about 1 minute, the antifreeze showed in the exhaust and I quit. Took about 2 gals. Hope it worked.<br />Jim

Ayuh,..............<br />That tells you that Atleast the exhaust manifolds are full of Antifreeze..............<br />

Hope it worked.

It'll Really $uck if it Didn't,............ Open the Block Drains,+ Look.................<br /><br />Good Luck.......

Re: Overheat while winterizing

That is not enough I can tell you for sure, when I fill my 4.3 with AF it takes about 4 gallons for the block and manifolds. I only do the AF because of salt water use.

Re: Overheat while winterizing

crazy charlie...........when you use the Camsco System, do you drain the block first before letting the antifreeze circulate? That's the way I have done it. My logic is even if A/F doesn't fill up the block, at least I can be assured that the water is gone.

Re: Overheat while winterizing

Dave,I guess the way you are doing it cant be bad.I do it exactly the way the directions state.There is a valve coming from the jug that allows just fresh water to run until the motor is warmed up enough and then I turn the valve which allows the AF to run and switch off the fresh water at the same time .All of this is done from the valve on the jug without shutting the motor.I believe this way aids to keeping the impeller primed so it sucks the AF at a good pace.I usually wait until the temp is about145 and then I turn the fresh water valve down a little so the temp climbs up to about 160 to be certain the stat is open and at that point I switch over to AF.Charlie

Hope you didnt damage the pump.
