Coolant temperature sensor.

Mine started to puke coolant out the the overflow tube ahead of the rear wheel when I parked it. Just a bad rad cap. I ordered the OEM part, but the caps sold by Moose Racing for quads fits too. I stole the cap off my LTZ for a week. I had the red 23psi model and the Rocket's stocker is 16psi. Sure ran cool that week. I don't know if the R3 system could handle 23psi for the long haul.
 
I think I can see where it is but there's a big hose in front that I cant move. Anyway. .Tried to get the rad cap tested at a rad shop but won't fit their equipment. The dude did the squeeze test an reckons ok. :-D Just done the 12min tune and fans kicking in just as needed now. No overflow ... sweet. Maybe I didn't fully seat the cap when I changed coolant and it wasn't building up enough pressure to give the fans an opportunity to fire ? Maybe I moved a dodgy sender wire. Who knows. Thanks for your input mate.
 
if u had air around the temp sensor it would not read right. it might get hot and push out the coolant.
did u bleed the air like warp said.
 
BTW - G'day @Andy I don't recall seeing your introduction!
Welcome from Brisbane.
Good idea to do an introduction (in the introduce yourself section) so others can say G'day too.
Most of us are friendly and don't bite.
Were in OZ are you from?
 
I always wondered why the owners hand book said, "have the coolant changed by an authorized Triumph dealer". Bennys video is the closed i've seen helping those with the coolant system. I bet if someone did a how to video on the coolant system a lot of newbies would appreciate it.
