Coolant flush question
I need to replace the coolant on my 05 RXT. How much would I expect to come out so I know how much should be added??

If you're changing it because it's contaminated you might want to flush the system with distilled water a few times first. I did this at the beginning of the season because I wanted to change coolant type.
i first drained the system. Filled with D water. Rode. Let cool. Drained. Rode. Emptied. Several times. Each time the water remained green, albeit a lighter shade. It took maybe 6 complete flush throughs to clear it.
i must be something to do with the water in the engine jacket and the thermostat being open/closed.
Nice to know all the old stuff is out though.
remember you need an aluminium safe coolant and I mixed 50/50 with distilled water (regular tap water can cause contaminants to build up over time).
my coolant is a fancy long life, high efficiency coolant. Hoping that it will last me out for as long as I own the ski!

how often do you guys change your coolant?

Since it's aluminum I'd never consider anything except zerex. That's my personal preference though. Owners manual will give you intervals

So when draining fluid I was going to access the water pump port that runs to coolant tank. I haven't started engine this year yet, should I warm it up first to get every thing hot?
