When I was at Road America on the 14th I had to change out my coolent for race stuff for the Inter. Group. I put something new stuff in, I cant remember the name but STT was selling it and it came in a Red bottle with a black sticker with white and yellow writing but Im not sure but the bottle was red. I was wondering since I live in this cold climate if this stuff is good to leave in the bike over winter, it won't freeze and crack the block will it, could you please tell me what brand it was so I can read the specs. Thanks, JON
Call the guys at STG (888-784-4327), they are probably the ones who sold it to you. They can give you the info your looking for.
The only way it wont freeze is if it has ethylene glycol in it coolant. (sorry cant spell) Thats what makes coolant slippery. So u will have to drain it or it will freeze. I know that kinda sucks but the only other choice is if u had a heated garage to keep it in.
Drain it. Its the easiest way to feel safe over winter. Why even risk it. Engines freeze from the top down. Bare cylinder heads are way more expensive than new coolant next year.
So a propylene based coolant will freeze? I have water wetter and distilled water in for now, was hoping I could change that for prop based coolant for winter time and then it'd already be good to go next year again.
The original poster doesn't say where he lives or the conditions the bike will be stored in. In any case, I've been leaving water wetter in my bikes over winter in an unheated garage ever since moving to the Charlotte NC area. Its basically a detached one stall garage I use as a dedicated bike workshop, its drywalled but not insulated. If the weather is going to be cold enough to be a concern I simply put a 60 watt bulb on the floor under the engine and it generates enough heat to keep it above freezing. Be warned however, do this at your own risk especially if you live in a colder climate.
I picked up some Liquid Performance propylene glycol. Works fine and protects to negative 30. 7th Gear is WAY cheaper than Liquid Performance and is basically the same stuff, should of bought that instead, more bang for the buck.
Sorry I havent been back I forgot about this post. I wasnt sure about the popy stuff as until now ive never heard of it. I know wetter water will freeze though have seen that happen in a race car. Looks like u have your ? answered already just felt bad I didnt get back to ya.
