Question 1

Where is the coolant circuit vent cap located on an Aprilia Scarabeo 125 scooter?

Accepted Answer

The coolant circuit vent cap on the Aprilia Scarabeo 125 scooter is the filler cap (1), located on the expansion tank. To access this cap, you must first remove the front inspection cover by following the instructions for removing the front fairing (page 42 of the manual).

Exact location: Once the front inspection cover is removed, the expansion tank is easily accessible. It can be identified by its MIN and MAX level markers engraved on the transparent or visible tank. The filler cap is located above or on the side of the expansion tank.

Essential points to follow:

Wait for the engine to be completely cold before handling the cap, as the coolant is under pressure and at very high temperature.
Gently loosen the filler cap by turning it two turns counterclockwise, without removing it immediately.
Wait a few seconds after loosening to allow any pressure to be released.
Warning: a breather tube (vent) is connected to the cap. Do not force it or remove it during your interventions.

Level check: When checking or filling, ensure that the coolant level is always between the MIN and MAX markers on the expansion tank. Do not exceed the MAX level to avoid leaks during engine operation.

For a complete coolant drain, contact an Official Aprilia Dealer. The manual recommends a drain every 2 years. Use only an appropriate coolant composed of 50% demineralized water and 50% antifreeze to ensure optimal protection against corrosion.
