Question about 2005 Yamaha YZF-R1

1 Answer

HI JUST PURCHASED A SMALL OFF ROAD BUGGY POWERED BY A YAMAHA R1 2005 MOTOR, AFTER 10 MINS OF RUNNING I CAN HEAR THE COOLANT BUBBLING/BOILING IN THE RADIATOR. I HAVE REMOVED THE THEMOSTAT WITH NO SUCCESS, RANG THE OWNER HE'S HADNT HAD THIS PROMBLEM. I QUIZZED HIM ABOUT THE TEMP GUAGE ON DASH HE SAID IT WORKS, AT IDEAL AT AROUND 78 DEGREES AND 110 DEGREES WHEN THE MOTORS WORKING HARD BUT THE ONLY READINGS I GET HAVE BEEN AROUND 20 DEGREES. THE RADIATOR IS MOUNTED HIGH AND THE THERMO FANS OPERATE AS SOON AS THE MOTOR STARTS. HOW CAN I CHECK TO SEE IF THE TEMP GUAGE IS WORKING AND ANYTHING ELES TO KEEP IT COOL THANKS

07 town car...after I drive my car for a while...it smokes a little when I cuts it off plus I hear a bubbling noise


bubbling noise is the radiator boiling. If you have a viscous fan hub the have it replaced as the engine is getting too hot. When you stop an engine thee is still heat being transferred from the combustion chambers into the coolant. When the engine temp is close to boiling , this heat will cause the coolant to boil when you shut the engine down

if no air in the system from internal heater or other places
new thermostat and radiator cap
good firm coolant hoses

old school air bleed
you fill coolant system with motor running
heater on in the car and thermostat open

what about these possibles
faulty coolant temp sender
head gasket failed
clogged radiator
cooling fans not spinning fast enough
or not coming on soon enough

Bubbling in resorvoir, and spills out, new thermostat and hose new, fan is running, what can it be?


Hi Bubbles in the resorvoir Usually is a head gasket fault ( the gasket is allowing compression pressure to enter the coolant system )
Unfortunately its a big job and exspensive
The only other thing is if the water is boiling ( like when a kettle boils ) But because you have
changed the thermostat and the fan is running i don`t think this is the problem
Good luck with this problem, Hope i have helped you

Wter coolant runs hot over 260


If you have checked all of your coolant levels, and don't see any leaks - then more than likely your thermostat is bad. The part isn't any more than $10 -$15 dollars and can be replaced in less than an hour.

Hope this helps!
