I use glycol and water (50%) in my Silver Bullet throttled engine as this should help keep the cast iron cylinder liners from rusting. I don't use any coolant in my hit and miss engines.

I use the same stuff I use for machining called TRIM. And I also use nothing in the hit miss engines.

Steve do you use the pre mix or do you use the consecrate I see on the bottle it looks like they mix with de-ionized water. Was just wondering if you mixed with regular water. I know the trim keeps rust to a minimum but after awhile it needs to be thinned out. Is it the same with the Water wetter?

Thank you all for the replies
One more question: Why don't you use the coolant that it normally uses for cars or motorcycles ?
Thanks .

I do use the premixed standard car / motorcycle coolant in not only my miniature engines but also my full sized stationary engines, I also use it in my water cooled electric motor on my milling machine. So far no cooling or corrosion problems in any of them.
Docs 'consecrated' coolant might be ok, but only if you are relying on divine guidance for protection :)

I am not using TRIM straight it is mixed with water same strength as the coolant I use. Not sure what you mean by your comment?

Doc, I think it was a little tongue-in-cheek humor based on the way "concentrate" came out in your earlier post - I presume the victim of auto-correct.

Pulling a liquid cooled model off the shelf and running for a couple hours out of a year's time, ordinary tap water suffices. Just like the fuel system, you put them back up dry. Conversely, with anti corrosion coolants, can be fill stored long term. The crankcase oil.....takes no side advocating a cooling fluid type or time period!

It was, sorry, I couldn't resist :)

adjective: consecrated

  1. (of a church or land) having been made or declared sacred.
    "a Christian burial in consecrated ground"

I prefer using only pure Glycol. I don't like having any water around my Cast Iron liners. Even a 50:50 Mixture with water makes the liners rust. It only takes a bit longer. The cooling capacity is the same as with water or mixtures.
