    If there is no danger of freezing: Coolant should be topped up - Only Scania Anti-corrosive should be used in the coolant to protect when the engine is stopped against corrosion. The correct level of anti-corrosive is 7-12% by vol- after the first start ume and this must never drop below 7% by volume.
  • Page 7: Checks Before Running

    If the fuel tank has been run dry or if the engine has not been used for a long time, bleed the fuel system, see page 26. Out of consideration to our common environment, your new Scania engine has been designed to be started with less fuel. Unnecessarily large fuel supply at start will always result in the release of uncombusted fuel.

    At temperatures below 0 °C: Note! Use only start aids recommended by Scania. - The starter motor may only be used for 30 seconds, after which it must rest for 2 minutes. If the engine has flame start: - Operating flame start without timer relay: Press the control button which also acts as a pre-glow button (max.
