Service Engine

c CAUTION: Avoid injury! Engine exhaust fumes can cause sickness or death:

· If it is necessary to run an engine in an enclosed area, use an exhaust pipe extension to remove the fumes.

· Always try to work in a well ventilated area.

Engine Oil

TS1411

Use oil viscosity based on the expected air temperature range during the period between oil changes.

The following oil is preferred:

· John Deere PLUS-50®- SAE 15W40

The following John Deere oils are also recommended if the above preferred oil is not available:

· PLUS-4® - SAE 10W30

· TORQ-GARD SUPREME® - SAE 5W30

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.

Other oils may be used if the John Deere oils listed are not available, provided they meet one of the following specifications:

· SAE 15W40 - API Service Classification CG-4, CF-4, CF, or MIL-L-46152B

· SAE 10W30 - API Service Classification CF-4, CF, or Military Specification MIL-L-2104F

· SAE 5W30 - API Service Classification CF

· CCMC Specification D5

· CCMC Specification D4

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

Arctic oils (such as SAE 0W30 or Military Specification MIL-L-46167B) may be used if temperatures fall below -30°C (-22°F), but reduce the oil change interval by 50%.

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 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.

Engine Coolant Drain Interval

When using COOL-GARD PRE-DILUTED SUMMER COOLANT (TY16036) or COOL-GARD CONCENTRATED SUMMER COOLANT (TY16034), Automobile and Light Duty Engine Service coolants, drain and flush the cooling system and refill with fresh coolant mixture every 24 months.

If above John Deere Automobile and Light Duty Engine Service coolants are not being used; drain, flush, and refill the cooling system according to instructions found on product container or in equipment Operator's Manual or Technical Manual.
