Notices some AF coming out from the shock tower (overflow) when I first started and brought sled home - level was fine. Drove sled for first time this weekend and put on 50 miles, in -25 temps. Noticed that through out the day it would spit some out every so often. Sled ran fine all day and engine temps appeared to be normal and coolant level seemed to also be normal at the time. Did seem to be slightly pressured up though when coolant would spit.

When I got home and sled was cold I notice the level was ~ 1 " below the cold fill line (was at the line beginning of day). So I did loose some coolant.

Anyone know what would cause/normal/fix/comments?

Thanks

it's normal for it to stabilize initially but maybee watch it to make sure you don't have a weak springon the cap or that it is leaking...

Thanks, I will monitor as I ride, I am hoping this is all it will take.

Has anyone else had these issues?

Let your sled idle

If you let your XP idle for 30-60 seconds before turning it off it wont happen.....If you turn off your sled before allowing the AF to cycle for 30-60 seconds overflow can occure.

Stopping a sled right away will increase internal temps since the AF is no longer cycling.

Good info, whats the easy way to check the pressure at which the cap is set for?

should say on the cap. I'd keep an eye on it. Usually as the sled cools and hoses contract, the level should go up, not down. At least that's how it's always been on my Polarii.

Brutis i don't know of any easy way, All i know is the AF is a cooling agent that cools as it cycles. Stop the cooling cycle to soon and the internal temps will increase.....On older model sleds they used to have overflow bottles but not any more. Now the overflow AF just hits the bottom of you belly pan.

Redline makes a product that's called Water Wetter that the NHRA Dragster community uses either 100% or as an additive to there cooling system to greatly reduce intermal heat. Works very good with sleds as well.
