More problems!....My wheeler was overheating and I noticed coolant leaking out of the weep hole. I took it to a local shop and they replaced the mech. seal . when I got home I rode it around a little to check it out and when warmed up, coolant in the resevoir was boiling and spraying out the top of the resevoir. There was enough pressure that when I gave it some gas the resevoir would expand. My fan never came on but when I wired it to run constant it didnt help.I checked the stat and its opening fine.....do i have a blown head gasket???

Thanks for any help

Frustrated.

 

With the engine cooled down the radiator toped off start the bike with the cap off the radiator and let it idle until it warms up. Once the stat opens you should see the coolant flowing/swiling in the radiator. If it's not then replace the impeller in the pump. Most of them are plastic and replaceable. If you start it up and there are constant bubbles coming out then you have a blown head gasket.
