Check Coolant In Surge Tank (200 HP Engine)

CAUTION: Explosive release of fluids from pressurized cooling system can cause serious burns.

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

IMPORTANT: John Deere Liquid Coolant Conditioner does not protect against freezing. Coolant conditioner prevents rust, scale, and liner cavitation.

NOTE: Check coolant every 500 hours or 6 months, or when replacing 1/3 or more of coolant. Add coolant conditioner as necessary.

1. Remove surge tank cap (1) and test coolant solution. Use one of the following kits to check coolant.

• 3-WAY Heavy Duty Coolant Test Kit (TY16175)

  Coolant test strips provide an effective method to check freeze point and additive levels of engine coolant. See your authorized dealer for 3-WAY Heavy Duty Coolant Test Kit and follow instructions on kit.

• COOLSCAN PLUS ®
