2j - Gilera Bi4

The coolant should be replaced every two years as follows:
Maintenance
- remove the two drain screws, located on the water pump cover
and the cylinder respectively (Fig . 14 - no. 1 and 2); when the
radiator plug is unscrewed, the coolant will flow out of them . To
complete drainage, lean the cycle over to the right;
- when the system is empty, replace the screws;
- refill with AGIP PERMANENT FLUID, covering
the radiator tubing ;
- idle the engine to eliminate any air pockets
in the circuit and top off the level, which
.must total 0.900 liter of coolant;
- tighten the plug make sure there are no
leaks with the cycle erect, which could only
be due to overfilling.
