MAINTENANCE Item 2 Cooling System Flush and Fill Coolant Flush and Fill Proper maintenance of the cooling system is vital to its performance and longevity. The cooling system must, on a constant basis, deal with cavitation, temperature / pressure swings, and continuous threats on the additive package. Once the additives have been depleted from the coolant, it will only be a matter of time until the engine components suffer.Refer to the How to Select Coolant section in this guide. Figure 28 Lubricating Oil filter Cooling System Inspection – Inspect the cooling system as follows: PERSONAL INJURY HOT COOLANT To avoid injury from slipping and falling, immediately clean up any spilled liquids.
To avoid scalding from the expulsion of hot coolant, never remove the cooling system pressure cap while the engine is at operating temperature. Wear adequate protective clothing (face shield, rubber gloves, apron, and boots). Remove the cap slowly to relieve pressure. Make a visual check of all lubricating oil lines for wear and/or chafing. If any indication of wear is evident, replace the oil lines and correct the cause. Check for oil leaks after starting the engine. 1. Inspect the radiator, condenser, coolant pump, engine oil cooler, freeze plugs, and heat exchanger for damage and leaks. 78 All information subject to change without notice. (Rev.
