KIT-DIAPHRAGM 2600167 - Caterpillar

You must read and understand the warnings and instructions contained in the Safety section of this manual before performing any operation or maintenance procedures.The Every Two Years interval is based on fuel consumption or 320 000 km (200,000 miles), whichever occurs first.Cooling System (Conventional HD Coolant/Antifreeze Only)
Drain/Clean/Replace Coolant
Clean/Flush the cooling system before the recommended maintenance interval if:* Coolant is heavily contaminated* The engine overheats frequently* Foaming is observed in the radiator* The oil cooler has failed, allowing oil to contaminate the coolant* Fuel has entered the cooling system and contaminated the coolant
If using a commercial HD coolant/antifreeze which meets ASTMD4985: drain, clean, and refill the cooling system Every Year or 241 500 km (150,000 miles), whichever occurs first.Use of commercially available cooling system cleaners may cause damage to cooling system components. Use only cooling system cleaners that are approved for Caterpillar engines that have aluminum cooling system and engine components.DO NOT use a cooling system cleaner that contains tri-sodium phosphate. Tri-sodium phosphate will damage the aluminum components in the engine.
A good time to inspect the water pump, replace the water temperature regulator, and replace hoses is when your engine's cooling system has been drained.Drain
1. Stop the engine and allow the engine to cool. Loosen the radiator filler cap slowly to relieve any pressure. Remove the radiator filler cap.2. Remove the cooling system drain plug(s) or open the drain valve. Open the cab heater valve to drain coolant from the cab heater. Remove the drain plug from the bottom of the water pump housing. Remove the drain plug from the bottom of the radiator. Allow the coolant to drain.
Dispose of used engine coolant properly or recycle. Various methods have been proposed to reclaim used coolant for reuse in engine cooling systems. The full distillation procedure is the only method acceptable by Caterpillar to reclaim the used coolant. Contact your Caterpillar dealer for information regarding disposal and recycling of used coolant.

1. Flush the cooling system with clean water to remove any debris.2. Clean and install all drain plugs and/or close the drain valve(s).
Fill the cooling system no faster than 19 L (5 US gal) per minute to avoid air locks.
3. Fill the cooling system with a mixture of clean water and Caterpillar Fast Acting Cooling System Cleaner. Add .5 L (1 pt) of cleaner per 15 L (4 US gal) of cooling system capacity. Install the radiator filler cap.4. Start and run the engine for a minimum of 30 minutes with the coolant temperature at a minimum of 82°C (180°F). Stop the engine and allow the engine to cool.5. Loosen the radiator filler cap slowly to relieve any pressure. Remove the radiator filler cap. Remove the cooling system drain plug(s) or open the drain valve(s). Allow the cleaning solution to drain. Flush the cooling system with clean water until the draining water is clear. Clean and install all drain plugs and/or close
