Temp Gauge Flashing

I have a 2001 Yamaha Venture 700 liquid cooled. The temperature gauge has started flashing after a few minutes of riding. Anyone know what causes this? There also seems to be smoke that comes out from the rear end of the sled under the passenger seat. Looks like there is something there for cooling. This is my first liquid cooled sled so I'm unfamiliar with what to do.

Thanks!

Andy

Think I figured it out.

I think there's a short in the passenger grip warmers causing the flash. Turning them off stops the flashing.

That steam coming up from under the seat is from the track throwing snow onto your heat exchanger. It is made to do that. If there were no snow to kick up there,eventually the sled would overheat. If doing your alot of trail riding on hard packed snow try and hit some powder once in a while.

Check coolant level, then lift the front end of the sled up high, remove coolant cap, start engine and warm up, this should help remove air in the coolant system. To help cooling engine, also consider add scratchers, see Holz Racing Products || ATV - 450R || UTV - RZR RZR-S || Sled - Rev IQ RMK. I will get a pair of these myself.

Since the light comes on after 5 mins it makes me think there is something more serious stuff going on, like water pump failure, but I guess since your heat exchangers are hot, this is probably not the case.

while your sled is running take off the coolant cap if you see antifreeze flowing then your pump is ok maybe thermostat problem .
