Valve Clearance (Exhaust) 0.610 mm (0.024 in)

Coolant

• 50/50 coolant solution (50% pure water and 50% anti-

freeze)

• 16 L (4.23 gal) capacity

Oil Capacity 15 L (4 gal)

Oil Standards

• Must adhere to Cummins

Engineering Standard

(CES) 20085

• Use of improper oils can result in engine damage. Use

only the required oils:

◦ 5W-40 (all ambient temperatures)

◦ 15W-40 (above 4 °C [40 °F] ambient temperature)

(use of GEO 15W-40 oil in ambient temperatures

below 4 °C (40 °F] could result in engine

turbocharger damage)

• A sulfated ash limit of 0.6% mass has been placed on

all engine lubricating oils recommended for use in

Cummins® B, natural gas engines. Higher ash oils can

cause valve and/or piston damage, cause spark plug

fouling, and lead to excessive oil consumption and

degradation of the catalyst.
