Hello all,
I have been noticing that my water temp light keeps turning on when I am moving through city street with a heavy traffic. I thought maybe it was due to hot day that might caused it until last weekend.
Last weekend, I was riding around in Washington DC with lots lots of intersection stops. My VROD's temp light was on all the way, until I saw a white smoke coming out between my legs. I pulled over and checked it. It was coolant that was building pressure in the reserve coolant tank. It exploded, yes exploded in my face. I think the pressure blew coolant through out of "overflown" cap, right on top of the reserve coolant tank (the plastic cap).
My face is okay and thank god I wore glass in that event. Coolant was all over on my bike, I cleaned it up. I could tell that something is wrong with my radiator system. I think a mech didn't bleed the air from radiator system that might caused this. I don't know. I inspected if there is leaking somewhere else. Nope there is no leaking of coolant other than blowing through reserve coolant tank. I think it is safe to ride back home as long I keep moving to bring cool-air to cool engine down.
I rode it back home with all of this. I didn't tried to overheat it by going more than 6k RPM all the way. I shut down the engine when I stopped at an intersection to prevent adding more heat to the engine.
Today, I added coolant to the radiator system and tested ride it. It seems okay but the light still coming on.
Some people said it could be a bad thermostat, bad gasket seal, or a cracked tube somewhere.
I would like to hear from you guys to see what do you guys think?
I am planning to work on this over this weekend. I am thinking to flush all coolant out and to inspect all radiator system before adding a new coolant into it.
One thing that bothers me a lot. I don't understand why coolant couldn't just go around in the radiator system. Maybe something is in the way or an air has stopped it from being circled. It seems something stopped from it to be circled and caused coolant to overflow, and then the pressure built and it exploded. (not an explosion but it blew up).
