Leaking from radiator pipee

3 posts in this topic

hey guys new here and dont know too much about bikes but I bought a yz426f about a month ago and i blew a radiator hose on it the last time i rode it (the one coming from the top of the left side of the radiator into the pipe that goes into the top end). I just replaced the hose and put new coolant in and it seems to be leaking right where the pipe meets the top end. Is this a gasket issue? It doesnt seem to be coming from the bolt that holds it in, and it is a pretty quick leak. have not started the bike yet either... I appreciate any advice!

Bro, did you snug up all the hose clamps? When you drain coolant from a water cooled engine, its a good idear to bleed all the air from the system, that way the pressure will be in the correct area of function.....

No bleeding of the system is necessary, just fill it, run it, and top it off.

 

The water outlet pipe at the head and the inlet pipe at the pump are both sealed by O-rings.  Remove the pipe(s), clean the bore up, and reseal it.
