COOLING SYSTEM: The Perkins diesel engine is water cooled. Check the coolant level at the radiator filler daily. Add a 50-50 mixture of water and antifreeze as needed. To drain and refill the system, do the fol- lowing:

1. Ensure that the machine is on level ground.

WARNING

To avoid personal injury, never remove the radiator pressure cap nor the reserve tank cap while the engine is running or immediately after it has stopped. Hot water may gush out, which can scald people nearby.

2.Remove the radiator filler cap.

3.Remove the drain plug from the side of the cylinder block in order to drain the engine. Ensure that the drain hole is not restricted. See Figure D.5.

4.Open the radiator drain cock at the bottom of the radiator in order to drain the radiator.

5.If necessary, flush the system with clean water.

6.Fit the engine drain plug and the radiator drain cock.

7.Fill the cooling system at the radiator filler with a 50- 50 mixture of water and antifreeze.
