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

c CAUTION: Avoid injury! Engine exhaust fumes contain carbon monoxide and can cause serious illness or death.

Move the machine to an outside area before running the engine.

Do not run an engine in an enclosed area without adequate ventilation.

• Connect a pipe extension to the engine exhaust pipe to direct the exhaust fumes out of the area.

• Allow fresh outside air into the work area to clear the exhaust fumes out.

Engine Oil


TS1411

• John Deere PLUS-50TM

The following oil are also recommended:

• John Deere TORQ-GARD SUPREME®

Other oils may be used if they meet one of the following:

• API Service Classification CE

• API Service Classification CD

• CCMC Specification D5

• CCMC Specification D4

Viscosity grade SAE 15W-40 is preferred.

If John Deere PLUS-50 engine oil and a John Deere oil filter are used, the oil and filter service interval may be extended by 50 hours.

If diesel fuel exceeding 0.5% sulfur content is used, reduce the service interval for engine oil and filter by 50%.

Checking Engine Oil Level

IMPORTANT: Avoid damage! Failure to check the oil level regularly could lead to serious engine problems if oil level is low:

• Check oil level before operating.

• Check oil level when the engine is cold and not running.

• Keep level between the FULL and the ADD marks.

• Shut off engine before adding oil.


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 machine safely. (See Parking Safely in the SAFETY Section).

2. Allow engine to cool.

3. Open hood.

4. Clean area around dipstick prior to removing it.


DM2006

5. Remove dipstick (A). Wipe it clean.

6. Install dipstick.

7. Remove dipstick and check oil level. Oil level should be between low and high marks on dipstick.

• If oil is low, add oil to bring oil level no higher than the “H” high mark on dipstick.

• If oil level is above the “H” high mark, drain to proper level.

IMPORTANT: Avoid damage! To prevent extensive engine wear or damage, always maintain the proper engine oil level. Never operate the engine with the oil level below the add mark or over the full mark.


8. Install dipstick.

9. Close hood.

Changing Engine Oil and Filter

c CAUTION: Avoid injury! Touching hot surfaces can burn skin. The engine, components, and fluids will be hot if the engine has been running. Allow the engine to cool before servicing or working near the engine and components.

IMPORTANT: Avoid damage! Change the oil more often if the machine is used in extreme conditions:

• Extremely dusty conditions.

• Frequent slow or low-speed operation.

• Frequent short trips.


1. Run engine to warm oil.

2. Park machine safely. (See Parking Safely in the Safety section).


DM2016

TS281

c CAUTION: Avoid injury! The radiator will be hot and can burn skin. Built-up pressure may cause explosive release of coolant when the radiator cap is removed:

• Shut off the engine and allow to cool.

• Do not remove the cap unless the radiator and the engine are cool enough to touch with bare hands.

• Slowly loosen the cap to the first stop to release all pressure. Then remove the cap.

Servicing Air Cleaner Elements

IMPORTANT: Avoid damage!

• When operating the machine in extreme heat, dust or other severe conditions, check the air restriction indicator daily.

• Never run the engine without the air cleaner elements installed.

• Do not wash the paper elements.

• Do not attempt to clean paper element by tapping against another object.

• Do not use pressurized air to clean element.

Recommended Engine Coolant

The following John Deere coolants are preferred:

• COOL-GARD™ PRE-DILUTED SUMMER COOLANT (TY16036).

• COOL-GARD™ CONCENTRATED SUMMER COOLANT (TY16034).

If neither of the recommended coolants is available, use a glycol base coolant that meets the following specification:

• ASTM D4985 (JDM H24A2).

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 Coolant Level

c CAUTION: Avoid injury! Explosive release of fluids from pressurized cooling system can cause serious burns:

• Shut off engine.

• Add coolant to radiator only when expansion tank is completely empty.

• Only remove filler cap when radiator is cool enough to touch with bare hands. Slowly loosen cap to first stop to relieve pressure before removing completely.

IMPORTANT: Avoid damage!

• Do not operate engine without coolant.

• Do not pour coolant into the radiator when the engine is hot.

7. Check condition of hoses. Check for leaks or loose connections.

8. Close hood.

Draining Cooling System

c CAUTION: Avoid injury! Explosive release of fluids from pressurized cooling system can cause serious burns:

• Shut off engine.

• Add coolant to radiator only when expansion tank is completely empty.

• Only remove filler cap when radiator is cool enough to touch with bare hands. Slowly loosen cap to first stop to relieve pressure before removing completely.

1. Stop engine and lock parking brake.

2. Open hood. Let engine cool.

3. Remove radiator cap.


DM2025
