2008 Phazer FX 144 4 stroke
I am having issues purging the coolant system and it is running really doggy any suggestions. this is my buddys sled just trying to help him out. when you open up the throttle the coolant overflow burps fluid and air
You might want to try posting on TY4stroke - lots of hints / links / stickies on that site - good bunch to offer help as well.
Never had that kind of issue with any of our phasers though.
You might have a head gasket going and is pressurizing the cooling system. Just a thought. I dont own a phazer however there was a post in the nytro forum about a similar issue a while back and a few people were suggesting it was the head gasket if my memory serves me right . Looking over on TY is good advice. A lot of knowledgeable. People over there.
