2000 Polaris RMK Indy 800
Pretty new to the snowmobile world, I picked up a 2000 Polaris RMK 800 for this season. I’m pretty familiar with JetSki and other Style engines and so I went over just about everything maintenance wise, except for flushing the coolant. I’ve heard it’s not good to have any air built up in the system? Also, I don’t see a drain plug anywhere so not sure how to approach that. Everything else checks out as far as I know. Thanks for any and all input!!
