hello every body my first post and it's a dandy. bought my first polaris 2001 scrambler 400 4x4 2 stroke radiator leaking into krank case can someone please help me thank you

 

Water pump seals and bearing is the usual cause if coolant overflows the vent tube from the counter balancer cavity. If it's leaking into the cylinder itself,could be a head or base gasket. #2,3,4. Dirt Cheap Yamaha, Honda, Arctic Cat & Polaris OEM Parts & Accessories – Cycle Parts Warehouse
If you don't have a manual here's a link to a free pdf service manual for a 98 400 as all the engines are basically the same mechanically.Look over the engine section and cooling section as to what's involved. http://gh-ftp.com/ORV%20Manuals/Pola...e%20Manual.pdf

 

thank u old polais tech

 

check your counter balancer oil too, its probably contaminated & milky.
