My 2000 polaris 400 scrambler is blowing water out of the radiator the guy I got it from just had the top end done and I just replaced the head gasket again after checking the surfaces of the head and cylider to make sure they were smooth and not warped or cracked and they seemed fine. Someone else told me to check the water pump seal, because if its bad it can cause the same problem is that true and if not can someone give me some ideas on what could be causing the problem.

 

just to let you know you posted in the Yamaha section it should be in the Polaris section might get a faster better response in the other section

 

thank you for letting me know my nephew posted this for me, I guess he must have went to the wrong section. I just reposted it in the polaris section.
