Coolant Leak ??

Redsvt · October 20th, 2012, 02:47 PM

I am going to clean this off and see if it comes back. Where could this coolant be coming from??? Bike is 2012 250R 4800 miles on it. Could this be a serious issue......

Clean it all up, start the bike, let it run till it's up to temperature. then inspect all the hose connections, thermostat housing gasket and where temperature sensor screws in, coolant tank connections and where the coolant hose connects to the top of the engine. Looks pretty dry, sure it's not just spilled coolant from topping up the coolant tank?

Check the cap of the radiator as well.

Problem solved, seems both ends of the hose that attaches to the thermostat and cap were leaking at each end. One of the screws was stripped so I tightend it with a pair of pliers. Seems whoever assemble that part stripped the screw.
