Engine Warranty Maintenance Statement
Maintenance, repair, or replacement of the emission control devices and systems on this engine, which are being done at the customer’s 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
Use oil viscosity based on the expected air temperature range during the period between oil changes.
The following John Deere oils are preferred:
Other oils may be used if above John Deere oils are not available, provided they meet the following specification:
• API Service Classification SG or higher
Checking Engine Oil Level
1. Park the vehicle safely. (See Parking Safely in the SAFETY section.)
2. Raise and secure cargo box.
3. Remove dipstick (A) and wipe it clean.
• Oil level must be between fill marks on dipstick.
• If oil level is low, add oil to bring oil level no higher than upper mark on dipstick.
• If oil level is above upper mark, drain to proper level. Determine cause of this condition and correct.
Changing Engine Oil and Filter
IMPORTANT: Avoid damage! Change the oil more often if the vehicle is used in extreme conditions: |
1. Run engine to warm the oil.
2. Park the vehicle safely. (See Parking Safely in the SAFETY section.)
3. Raise and secure cargo box.
4. Place drain pan under engine drain plug.
5. Open drain valve (A) on the left side of engine and drain oil into oil drain pan. Allow oil to drain completely.
6. Remove and discard oil filter (B) on front of engine. Wipe off filter base on engine.
7. Put a light coat of clean engine oil on gasket of new oil filter.
8. Install new filter until rubber gasket contacts filter base. Tighten filter an additional one-half turn.
10. Pull off oil fill cap from filler opening (C).
IMPORTANT: Avoid damage! Do not overfill crankcase with oil. Oil capacities given are with engine and crankcase completely dry. Some oil will remain in engine after draining. |
11. Add oil no higher than upper mark on dipstick. Use approximately 1.3L (1.37 qt) of oil. Do not overfill.
13. Start and run engine at idle to check for leaks. Stop engine. Fix any leaks before operating.
14. Check oil level, add oil if necessary.

9. Connect fuel line couplers to new filter, making sure couplers are securely connected.
Adjusting Direct Fuel Injection (DFI) Pump
NOTE: The direct fuel injection pump automatically compensates fuel delivery for altitude changes. It is calibrated by the engine manufacturer and should not require any adjustments.
If engine is hard to start, lacks power, or runs rough, check the TROUBLESHOOTING section of this manual.
After performing the checks in the troubleshooting section, if your engine is still not performing correctly, contact your John Deere dealer.
Cleaning Engine Compartment
1. Park the vehicle safely. (See Parking Safely in the SAFETY section.)
2. Raise and secure cargo box.

IMPORTANT: Avoid damage! Cooling fins must be clean to prevent engine from overheating and to allow adequate air intake. |
1. Park the vehicle safely. (See Parking Safely in the SAFETY section.)
IMPORTANT: Avoid damage! High-pressure water or air can damage cooling fins or other engine components. Use water from a hose or reduce compressed air pressure to 210 kPa (30 psi). |
4. Remove all dirt and debris from radiator fins (B) and fan shroud (C) using compressed air or water. Flow of compressed air or water should be from back to front.
Checking Coolant Level
1. Park the vehicle safely. (See Parking Safely in the SAFETY section.)
4. Check recovery tank (A) coolant level:
• If engine is warm, coolant level should be between the FULL line (B) and the LOW line (C).
• If engine is cold, coolant level should be at the LOW line (C) on the recovery tank.
5. Remove recovery tank cap (D) if necessary to add coolant.
6. Add coolant mixture to recovery tank.
IMPORTANT: Avoid damage! Installing suction hose incorrectly will not allow coolant into the coolant system. Do not allow bottom of hose to touch bottom of bottle or bend upwards out of coolant. |
7. Install and tighten recovery tank cap.
Service Cooling System Safely
Servicing Cooling System
IMPORTANT: Avoid damage! Follow all service procedures exactly. If not equipped to perform this work, see your John Deere dealer for service. |

2. Remove radiator cap and add recommended coolant mixture to radiator until coolant runs out of bleed port.
3. Install and tighten bleed screw with seal washer.
4. Add additional coolant mixture to radiator until coolant run out of overflow port and into the recovery tank.
IMPORTANT: Avoid damage! Position hose slightly above bottom of recovery tank. Do not allow hose to contact bottom of recovery tank or bend upwards out of the coolant. |
6. Remove recovery tank cap and add coolant mixture to recovery tank until it is approximately half full.
IMPORTANT: Avoid damage! If coolant temperature indicator comes on while engine is running, stop engine and add more coolant mixture to radiator. |
8. Start and run engine at medium speed until upper and lower radiator hoses have become warm (10 - 15 minutes), indicating thermostat has opened and coolant is circulating.
10. Loosen bleed screw and allow air to bubble out until air bubbles are no longer visible at bleed port. Tighten bleed screw completely.
11. Remove radiator cap and add recommended coolant mixture to radiator until coolant runs out of overflow port and into the recovery tank.
13. Run engine until cooling fan starts, indicating the engine and coolant has reached operating temperature.
14. Stop engine and remove key.

Flushing Cooling System
2. Prepare a cooling system flushing solution using clean water and John Deere Cooling System Cleaner, John Deere Cooling System Quick Flush, or an equivalent.
3. Fill radiator completely with flushing solution. Install and tighten radiator cap.
4. Start and run engine until it reaches operating temperature.
|
c CAUTION: Avoid injury! Engine and coolant will be hot. Use a thick rag or gloves to protect your skin.
|
6. Turn radiator cap slowly to the stop to release system pressure. Remove radiator cap.
7. Drain cooling system immediately into a container before rust and dirt settle:

8. After all solution has drained, connect radiator hoses and tighten engine block drain screws.
9. Remove and clean recovery tank.
10. Install the recovery tank.
11. Fill cooling system with recommended coolant mixture.
Recommended Engine Coolant
The following John Deere coolants are preferred:
• COOL-GARD II® PRE-DILUTED SUMMER COOLANT (TY26576).
• COOL-GARD II® CONCENTRATED SUMMER COOLANT (TY26573).
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.
Checking Radiator Hoses and Clamps
1. Park the vehicle safely. (See Parking Safely in the SAFETY section.)
NOTE: Visually inspect hoses for cracks and wear. Squeeze hoses to check for deterioration. Hoses should not be hard and brittle, nor soft or swollen.
6. Check radiator hoses (A) between intermediate tubes and engine for damage or cracking. Replace if necessary.
7. Check hose clamps (B) and tighten or replace as needed.
8. Check radiator hose (C) between intermediate tubes and radiator for damage or cracking. Replace if necessary.
9. Check hose clamps (D) and tighten or replace as needed.
Checking Spark Arrestor
1. Park the vehicle safely. (See Parking Safely in the SAFETY section.)
2. Allow vehicle to cool completely.
3. Remove screw (A) securing spark arrestor (B) to muffler exhaust pipe. Retain the screw.
5. Make sure deflector screen inside arrestor is not plugged or damaged:
• If plugged, spray with carburetor/choke cleaner and blow dry with low pressure compressed air.
