Monitoring the Cooling System

Monitoring the Cooling System - Ops - DD5

The cooling system must be full for proper operation of the engine.

Warning: HOT COOLANT

To avoid scalding from the expulsion of hot coolant, never remove the cooling system pressure cap while the engine is at operating temperature. Wear adequate protective clothing (face shield, rubber gloves, apron, and boots). Remove the cap slowly to relieve pressure.

  1. Check the coolant level daily and maintain it at the full level.
  2. Add coolant as required, but do not overfill. Before adding coolant, refer to "How to Select Coolant" for the listing of required intervals using the recommended coolants
