Refractometer.

It shows when the Anti-Freeze will freeze at.

I think that you are referring to a hydrometer. A refractometer measures light.

I do the same thing but once it's warmed-up before I run the anti freeze thru I drain the block of water plug it back up and then run the anti freeze.

Did it last year and we had -20* for 7 days in a row and not a problem.

Actually, Hyper kid is correct. A refractometer is a very accurate way of checking your freeze point. I believe the refractometer measures the amount of light that passes through a sample of antifreeze.

I used to sell them when I was Snap On dealer.

If I wanted to put in a Tee in, to attach a hose for flushing, where do these normally get installed, on the input side of the pump? I'd imagine you'd have to do that to prevent it from burning up the impeller for the lack of water! :rolleyes: What kind of valve would you put there? Is there something at the hardware store I can pick up?

Once you put this valve in, do you just attach a hose to a bucket of antifreeze and let it suck it into the motor?

Seems like keeping antifreeze or the red stuff would be better than being empty... less corrosion?? :confused:

I stand corrected :D :drink: ....if Biggus is right!!

Hey Biggus,
Did you get that email yesterday from my buddy Hugh? How did it look?

Re: Is this motor winterized safely?
 

I usually start with 5 gallons of AF per motor, and stick my hand in front of the exhaust and make sure I can taste antifreeze coming out of the exhaust. Just a touch from your finger on your tongue won't hurt you. (Maybe that's what is wrong with me though). You can usually see the pink color to it as your exhaust sprays it out as well.
