I'm replacing the orings in the top of the cylinder head and I was wondering if anyone has any tips for me. I believe it's pretty easy and you just unbolt the cylinder cover and replace the orings and coolant. Is it a good idea to flush the whole cooling system now as well? should I run a cleaner through it like you would in a car? Any other things to do while I have it drained of coolant?

Thanks!

Flushing isn't a bad idea, but cleaner is not usually necessary. Remove the coolant before you remove the head, if you take the head off first, there's a good chance coolant will flow down into the crankcase. Bearings don't like antifreeze.

I like to put a film of grease on the O rings, it helps keep them in place when you install the head.

Thanks for the heads up on draining the coolant. What type of grease do you use on the orings? kinda a newbie questions but do the orings sit on the the cylinder side or do they go into the top of the cylinder head? Also should I use regular antifreeze that I would use in my car like prestone or something special for sleds? One more question, I want to flush my chaincase and was wondering what the best way to do it is. Should I drain, refill and drive it around a little and drain refill again? will that get all the gunk out of it?

So i'm about to start working on my sled and realized that I don't know where the coolant drains from. In the manual it only says you should periodically drain and refill but it doesn't say how. Any Tips?

One more thing, is there any certain way to refill with coolant? I was reading you should purge the air out if air becomes trapped but im not sure if i need to do this when i refill with coolant.

do you have a hard copy of the manual, or do you have it on your pc/online? if you have an electronic version, care to share it?
