High-quality ethylene glycol anti-
freeze containing corrosion inhibi-
tors for aluminum engines
Coolant quantity:

routes):
2.00 L (2.11 US qt, 1.76 Imp.qt)
Coolant reservoir capacity (up to the
maximum level mark):
0.25 L (0.26 US qt, 0.22 Imp.qt)
13. Install the radiator cap.
14. Install the coolant reservoir cap.
15. Start the engine, let it idle for sev-
eral minutes, and then turn it off.
