Service Engine
Engine Warranty Maintenance Statement
Maintenance, repair, or replacement of the emission control devices and systems on this engine, which are being done at the customers expense, may be performed by any non-road engine repair establishment or individual. Warranty repairs must be performed by an authorized John Deere dealer.
Avoid Fumes
Engine Oil
Choose oil viscosity based on the expected air temperature range during the period between oil changes.
John Deere PLUS-50 oil is recommended. John Deere TORQ-GARD SUPREME and oils meeting ACEA Specification E4/E5 may also be used.
Other oils may be used if they meet one or more of the following: API Service Classification CI-4, API Service Classification CH-4, or ACEA Specification E3.
Multi-viscosity diesel engine oils are preferred. Do not use break-in oils.
Checking Engine Speeds
Check engine speeds when engine is warmed up and not under load.
Observe tachometer.
ˇ Slow idle (no load) - 950 rpm
ˇ Fast idle (no load) - 2600 rpm
If above engine speeds are not to specifications, see your John Deere dealer.
Checking Engine Oil Level
NOTE: Check oil twice a day if you run engine over 4 hours in a day.
Make sure engine is cold when checking engine oil level.
1. Park the machine safely. (See Parking Safely in the SAFETY section.)
IMPORTANT: Avoid damage! Dirt and contamination can enter engine when checking oil level. Clean area around dipstick before removing. |
2. Remove dipstick (A). Wipe with a clean cloth.
5. Check oil level on dipstick. Oil level should be between levels (B) and (C) on dipstick.
b. Add proper engine oil until oil level is within operating range on dipstick. Do not overfill.
8. If oil is above level (B) on the dipstick, drain to proper level.
Changing Engine Oil and Filter
1. Run engine to warm the oil.
2. Park machine safely. (See Parking Safely in the SAFETY section.)
3. Place drain pan under oil drain located on left side of engine.
5. Wipe dirt from around oil filter (B).
6. Turn filter counter-clockwise to remove.
7. Put a light coat of clean engine oil on the gasket of new filter.
8. Install replacement oil filter by turning filter clockwise until gasket contacts filter base. Tighten additional one-half turn.
9. Install drain plug. Do not overtighten.
ˇ All models engine oil capacity is 7.5 L (7.9 qt).
13. Start and run engine at idle to check for leaks.
14. Stop engine. Fix any leaks before operating.
15. Check engine oil level and add oil if necessary.

Service Cooling System Safely
Checking Coolant Level
1. Park the vehicle safely. (See Park Safely in the SAFETY section.)
4. Check recovery tank (A) coolant level:
ˇ If engine is warm, coolant level should be between the FULL HOT line (B) and the FULL COLD line (C).
ˇ If engine is cold, coolant level should be at the FULL COLD line (C) on the recovery tank.
5. Remove recovery tank cap (D) if necessary to add coolant.
6. Add pre-diluted coolant or specified ratio of antifreeze and water.
Recommended Engine Coolant
The following John Deere coolants are preferred:
ˇ COOL-GARDŽ PRE-DILUTED SUMMER COOLANT (TY16036).
ˇ COOL-GARDŽ CONCENTRATED SUMMER COOLANT (TY16034).
If neither of the recommended coolants is available, use a glycol base coolant that meets the following specification:
Check container label before using to be sure it has the appropriate specifications for your machine. Use coolant with conditioner or add conditioner to coolant before using.
If using concentrate, mix approximately 50 percent antifreeze with 50 percent distilled or deionized water before adding to cooling system. This mixture will provide freeze protection to -37 degrees C (-34 degrees F).
Certain geographical areas may require lower temperature protection. See the label on your antifreeze container or consult your John Deere dealer to obtain the latest information and recommendations. Never exceed the maximum dilution rate for the coolant you are using. Exceeding the maximum rate will greatly reduce the coolant effectiveness.
Servicing Cooling System
Draining Cooling System
1. Park machine safely. (See Parking Safely in the SAFETY section.)
4. Slowly open radiator cap (A) to the first stop to release all pressure.
5. Close radiator cap tightly.
6. Position drain pan under radiator petcock (B). Open petcock and drain coolant.
7. Position drain pan under engine block petcock (C) at left side of engine. Open petcock and allow all coolant to drain.
8. After coolant drains from the recovery tank, remove radiator cap.
9. Close radiator petcock and engine block petcock.
Flushing Cooling System
1. Fill cooling system with clean water and John Deere Cooling System Cleaner, or John Deere Cooling System Quick Flush or an equivalent. Follow directions on container.
2. Install and tighten radiator cap.
3. Start and run engine until it reaches operating temperature.
5. Open radiator petcock and engine block petcock.
6. Drain cooling system immediately before rust and dirt settle.
7. Close radiator petcock and engine block petcock.
Filling Cooling System
NOTE: John Deere COOL-GARD coolant is recommended when adding new coolant to the cooling system.
Follow the directions on the container for correct mixture ratio.
ˇ Cooling system capacity is 6.2 L (6.6 qt).
3. Install and tighten radiator cap.
4. Run engine until it reaches operating temperature.
6. Allow engine to cool. (Some coolant may be drawn into the radiator from the recovery tank during cool down.)
8. Check recovery tank (A) coolant level:
ˇ After engine cools, coolant level should be at the FULL COLD line (B) on the recovery tank.
9. Remove cap (C) from recovery tank to add coolant if necessary.

a. Position drain pan under fuel filter.
b. Loosen drain plug (A) at bottom of fuel filter or bowl, if equipped, two or three turns.
c. Loosen air bleed valve (B) on fuel filter head and drain water from bottom until fuel starts to drain out.
d. When fuel starts to drain out, tighten drain plug (A) securely.
5. After draining water from the fuel filter, the filter must be primed by bleeding all air from the fuel system.
a. Operate primer plunger (C) on the fuel filter header until fuel flow is free from air bubbles.
b. Tighten air bleed valve (B) securely, and continue to pump primer ten times or until resistance is felt.
6. If the fuel system needs further bleeding, see Bleeding Fuel System in SERVICE ENGINE.
Replacing Fuel Filter Element

5. Install new filter element by pushing up firmly into mounting base, then turn clockwise until it locks in place. Be sure element is firmly seated in base.
NOTE: A plug is provided with the new element for plugging the used element.
6. Bleed the fuel system by pressing down the primer button (D) on top of filter until resistance is felt or fuel flows freely from the bleed valve. Tighten bleed valve (B).
Bleeding Fuel System
Any time the fuel system has been opened up for service (lines disconnected or filter removed), it will be necessary to bleed air from the system.
NOTE: Fuel tank must be full of fuel before bleeding fuel system.
2. Pump the hand primer (B) on filter mounting base until a noticeable amount of fuel and air comes out of vent opening. Continue pumping until fuel runs out smoothly without spitting.
3. Close air bleed valve, and pump the hand primer ten more times or until resistance is felt.
