Cooling System
Do not perform this maintenance until you read and understand the material in the Safety and Cooling System Specifications sections of this publication.This procedure is to be used for normal maintenance of cooling system surfaces to return to "like new" condition. For heavy build-up of scale and deposits, a severe acid-type commercial cleaner or mechanical cleaning will be required.
Refer to the Cooling System Specifications for additional information regarding appropriate Flush/Fill for your application.Clean/Flush Coolant
If changing thermostats prior to this interval, go to step 5, Replace Thermostat, Gaskets and Seal.1. Stop the engine and allow to cool. Loosen the radiator filler cap slowly to relieve any pressure and remove the cap.2. Remove the cooling system drain plug(s) or open the drain valve and allow the coolant to drain. Open the cab heater valve to flush coolant from the cab heater. 3. Remove the drain plug (1) on bottom of water pump housing and/or radiator. Check water pump breather filter 4N1400 (2) for blockage or debris and replace if necessary.Water Pump Seal
Over concentration of coolant additive (Conditioner), mineral deposits from hard water or cooling system contamination can accelerate the wear on the water pump coolant seal. The cooling system maintenance interval provides an opportunity to inspect and replace the water pump seal if necessary to reduce coolant leakage.Dispose of used engine coolant 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 Caterpillar Service Technology Group:Outside Illinois: 1-800-542-TOOLInside Illinois: 1-800-541-TOOLCanada: 1-800-523-TOOLRefer to Service Magazine article dated November 13, 1989 and/or Engine News article dated November 1989 for information regarding disposal and recycling of used coolant.4. Clean and install all drain plugs and/or close drain valve. All tools shown or mentioned in the following Disassembly and Assembly procedure are available at any Caterpillar dealer.Replace Thermostat, Gaskets and Seal
If replacing thermostats ONLY, drain the coolant from the cooling system to a level below the thermostat housing. 5. Disconnect hose assembly from radiator to thermostat housing assembly.6. Remove six bolts (1) that fasten the thermostat housing to the cylinder head and remove thermostat housing (2) and gaskets. 7. Remove thermostat (3) from the housing. 8. Remove lip-type seal (4) from the housing. Use tooling [Slide Hammer Puller (1P0074), Bearing Cup Puller Attachment (8B7554) and Leg (7S7786)] to remove seal from the housing. The thermostats can be reused if they are tested and meet the test specifications below and are not damaged or have excessive buildup of deposits. Thermostats should begin to open and be fully open as indicated in the following chart. 9. Replace thermostat, gaskets and seal.Install Thermostat
Caterpillar engines incorporate a shunt design cooling system and require operating the engine with a thermostat installed.
Inspect gaskets before assembly and replace if worn or damaged. 10. Install lip-type seal (1) in housing with tooling (A) [Driver Group (1P0510)]. Install the seal with the lip of the seal away from the
