Green screen help with dads Yamaha Grizzly

[okie/texan]

So my pops has a 2004 or 2005 Yamaha Grizzly 660. He has changed the radiator with heat sensor, thermostat and fan. Took it out today and still overheated. Is the only thing left to fix/replace be the water pump??? How could I check to see if it is good or not?

Thanks for any help.

Are you sure the ngine is actually overheating? Meaning have you measured the motor against what the guage may say? I might pull the water pump for exploration reasons, and to also flush the engine really good in case of blockage. I'm more automotive than atv, but is it possible that a blown gasket somewhere is acting like a head gasket issue and pushing hot exhaust gases into the coolant?
