Has anyone ever changed out the anti freeze on the 900 classic? If so, how did you do this ? Thanks for the Info
I've done it twice to my '08 900 Classic LT. It's very easy to do. I suggest you acquire the shop manual. It will take the guess work out.
Left Side Coolant Tank Cover Bolt
Reserve Coolant Tank Cover
Coolant Reserve Tank Cap. Turn over the reserve tank, and pour the coolant out.
Remove the fuel tank
Remove the radiator cap in two steps. First turn the
cap counterclockwise to the first stop. Then push and turn
it further in the same direction and remove the cap.
Place a container under the coolant drain bolt ( it's located on the bottom, R/H side of the engine), then remove the drain bolt. The coolant will drain from the radiator and engine.
Install the coolant reserve tank.
Soft or distilled water must be used with the antifreeze
(see Specifications section) in the Shop Manual's cooling
If hard water is used in the system, it causes scale
accumulation in the water passages, and considerably
reduces the efficiency of the cooling system.
Water and Coolant Mixture Ratio (when recommended)
Soft Water : 50%
Coolant : 50%
Freezing Point : −35°C (−31°F)
Total Amount : 2.2 L (2.3 US gt.)
Torque - Coolant Drain Bolt: 9.8 N·m (1.0 kgf·m, 87 in·lb)
Fill the radiator up to the filler neck with coolant (I suggest adding a "Water Wetter" that you can buy at any auto parts store.
○Pour in the coolant slowly so that it can expel the air
from the engine and radiator.
○Choose a suitable mixture ratio by referring to the
coolant manufacturer’s directions. (I use Honda's HP Coolant solution. It's pre-mixed and ready to pour in.)
Check the cooling system for leaks.
Tap the radiator hoses to force any air bubbles caught
Fill the radiator up to the filler neck with coolant.
Install the radiator cap.
Fill the reserve tank up to the “F” (full) level line with coolant and install the cap. Install the fuel tank
Start the engine and warm it up thoroughly until the radiator
fan turns on and then stop the engine.
Check the coolant level in the reserve tank several times
while the engine is cooling down, and replenish as necessary.
If the coolant level is lower than the “L” level line, add coolant to the “F” level line.
Do not add more coolant above the “F” level line.
Hope this helps.
