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.
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.
