COOLING SYSTEM
W A R N I NG
HOT COOLANT CAN BURN SKIN
Do not remove cap if radiator is hot.
The Ranger 405D is shipped with coolant in the radiator. Check
the coolant level by observing the level in the radiator and
recovery bottle. Add 50/50 antifreeze / water solution if the level is
close to or below the"LOW" mark. do not fill above the "FULL"
mark.
Remove radiator cap and add coolant to radiator. Fill up to the top
of the tube in the radiator filler neck which includes a connecting
hose coming from the thermostat housing.
To drain the coolant, remove the plug in the side of the chassis
and open the petcock on the engine block which is located below
and to the left of the starter motor. Open the radiator cap to allow
complete drainage.
Tighten the petcock, replace the chassis plug and refill with 50/50
antifreeze/water solution. Use automotive grade (low silicate)
ethylene glycol antifreeze. The cooling system capacity is 4 litres
(1 US.gals). Squeeze upper and lower radiator hoses while filling
to bleed air from system coolant. Replace and tighten the radiator
cap.
CA U T I O N
Always premix the antifreeze and clean tap after before
adding to the radiator. It is very important that a precise
50/50 solution be used with this engine year round. This
gives proper cooling during hot weather and freezing
protection to 37° C (-34° F).
Cooling solution exceeding 50% ethylene glycol can result
in engine overheating and damage to the engine. Coolant
solution must be premixed before adding to radiator.
Periodically remove the dirt from the radiator fins.
Periodically check the fan belt and radiator hoses.
Replace if signs of deterioration are found.
Tightening the Fan Belt
If the fan belt is loose, the engine can overheat and the battery
looses its charge. Check tightness by pressing on the belt midway
between the pulleys. It should deflect about 6mm (.25 in) under a
load of 9 Kg (20 lbs).

FUEL
At the end of each day's use, refill the Ranger 405D fuel tank to
minimize moisture condensation and dirt contamination in the fuel
line. Do not overfill; leave room for the fuel to expand.
Use only fresh, No. 2 grade DIESEL fuel. Do not use kerosene.
See the Engine Operator's Manual for instructions on replacing
the fuel filter.
Bleeding the Fuel System
You may need to bleed air from the fuel system if the fuel filter or
fuel lines have been detached, the fuel tank has been ran empty
or after periods of long storage.
It is recommended that the fuel shutoff valve be closed during
periods of non-use.
The Kubota D1105 Perkins 403C-11 engine supplied with the
Ranger 405D is equipped with an automatic bleeding mechanism
that functions when the fuel pump is actuated. It is generally not
necessary to open a vent screw or fuel line fitting to bleed the fuel
system.
To avoid personal injury, do not bleed a hot engine. This could
cause fuel to spill onto a hot exhaust manifold, creating a danger
of fire.
Bleed the fuel system as follows:
1. Fill the fuel tank with fuel.
2. Open the fuel shut off valve (vertical position of handle) on the
Fuel Filter.
3. Press and hold the glow plug button for 10 to 20 seconds
4. Check to see that fuel is flowing through both fuel filters
5. Follow the normal STARTING procedures.
Fuel Filter
1. Check the fuel filter and fuel pre-filter for water accumulation
or sediment.
2. Replace the fuel filter if it is found with excessive water
accumulation or sediment.
Empty the fuel pre-filter.
Engine Adjustment
Adjustments to the engine are to be made only by a Lincoln
Service Centre or an authorised Field Service Shop.
