Bleeding coolant
NOTE :
Check to see if your vehicle is equipped with the self-
bleeding coolant pump cover and coolant bottle. If it is,
bleeding coolant is not required.
The coolant bleed bolt is located in the top right corner
of the coolant pump cover (right side of engine). Access
to it is difficult. If you are unfamiliar with coolant
bleeding, have an authorized Cannondale dealer bleed
the coolant.
1. Make sure the coolant system is completely cold and
you are wearing safety glasses and protective rubber
gloves. Have a few clean rags handy to wipe up any
spills.
2. Place a thick towel over the coolant bottle cap and
slowly remove the cap to release any residual pressure.
3. Fill the coolant bottle to the LEVEL mark with the
specified coolant.

4. Loosen the bleed bolt on the water pump cover and
allow any trapped air to escape. It is not necessary to
remove the bolt.

5. Continue bleeding the system until only coolant flows
out (no air). Then, tighten the bleed bolt.
6. Refill the coolant bottle to the LEVEL mark when
completed.
7. Reinstall the coolant bottle cap.
8. Start the engine and allow to idle for 3 minutes. Quickly,
touch the radiator. If it is warm the system was bled
properly. If it is cool to the touch, the system was not
bled properly. The procedure must be repeated.
9. Shut off the engine and wait for the system to cool
completely and repeat this procedure.
