N96250-UN-12DEC11

A - Surge Tank

Recommended Service Interval
Check Coolant Level	Daily

1. CAUTION: The explosive release of fluids from pressurized cooling system can cause serious burns.

   If surge tank cap must be removed, do not remove when engine is hot. Shut engine off and wait until cap is cool enough to touch with bare hands. Slowly loosen cap to relieve pressure before removing completely.

   Never add coolant when engine is overheated. Wait for it to cool.

   IMPORTANT: DO NOT use methoxyl propanol antifreeze in the cooling system. It may damage cylinder sleeves and seals.

   Stop-leak additives can plug radiator, causing overheating and engine damage. Do not use coolants that contain a stop-leak additive.

   Check coolant in surge tank (A) daily, while engine is cold. Coolant level in surge tank must remain between maximum cold level and minimum cold level marked on tank. Remove surge tank cap and add coolant as necessary. See DIESEL ENGINE COOLANT in Fuel, Lubricants, and Coolants section for coolant specifications.

2. If surge tank becomes completely empty, check system for leaks and repair as necessary.
