MY son just baught a Ski DOO 521cc. It wont keep coolant in it acts like there is a bubble or something blocking.Is there a special way to add coolant or a bleeder i dont know about?

What do you mean it won't keep coolant in? Is it leaking? Lift the front of the machine up higher than the back so any air will come out of the heat exchangers in the back of the sled.

It almost acts like its overheating but its not hot? it runs good and has equal compression in both cylinders cuz at first i was thinking blown head gaskets

Is there coolant on the ground? How do you know it won't keep it in?

 

[reott7399]

It pushes coolant out the overflow.

That usually means that the coolant system isbeing pressurized by engine compression. You have a bad head or base gasket in the engine.
