Checking the Coolant Level (Cold Check)

Checking the Coolant Level (Cold Check) - Gen 5 DD15 - Ops - #7628

Check coolant level as follows:

  1. Ensure that all coolant plugs in the bottom of the radiator and on the radiator outlet pipe are secure and tight.
  2. Check the coolant level. The cooling system is correctly filled when the coolant is between the full and low marks on the surge tank.
  3. If necessary, fill the surge tank with approved coolant; see How to Select Coolants. Do not overfill the cooling system as overfilling will cause the surge tank to push coolant out of the overflow.
