<FONT face=Arial size=2>I just replaced the piston and rings in a 2000 Xplorer 400 and I thought I read in one of the posts that you need to purge any air out of the cooling system. Is it necessary and is there a specific way to do it? I searched on several different subjects but didn't find the answer anywhere. Thanks for the help.</FONT>

 

if its necesary you better do it because your motor will run hot. im not familiar with your atv but check that out because its better to be safe. oh yeah a service manual would had told you if you need to do it and how to do it.

 

i think there is a bleeder screw on the head you can crack and all the air should escape there
