KIT-GASKET 1247568 - 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.This maintenance is to be performed at the fuel interval specified in the Maintenance Schedule. Before proceeding with this maintenance, perform all previous maintenance interval requirements.Thermostats
Replace Thermostat, Gaskets and Seal
Refer to the Service Manual for detailed instructions regarding Disassembly and Assembly of the Cooling System.Replacing the thermostats prior to failure is a recommended preventive maintenance practice because it reduces the chances for cooling system problems and unscheduled downtime.This maintenance is to be performed with the cooling system cleaned and drained or the coolant drained to a level below the thermostat housing.
Failure to replace your thermostats on a regularly scheduled basis could cause severe engine damage.
If replacing thermostats ONLY, drain the coolant from the cooling system to a level below the thermostat housing.1. Loosen hose clamps and remove hose from elbow. Disconnect hose assembly from thermostat housing assembly.2. Remove bolts from elbow and remove elbow and thermostat housing assembly.3. Remove the gasket, thermostat and seal from the housing.Flush-If Using Standard Type Antifreeze ONLY
1. Refill the cooling system with clean water mixed with the proper concentration (six to ten percent) of Fast Acting-Type Caterpillar Cooling System Cleaner (if you did NOT use Standard-Type Cleaner). Tighten cooling system filler cap. For proper cooling system maintenance cleaning, refer to label directions for the type of Caterpillar Cooling System Cleaner used in your cooling system.2. Start and run (operate) the engine to circulate fluid in the cooling system.3. Stop the engine and allow to cool. Loosen cooling system filler cap and drain plugs.4. Drain the cleaning solution. Flush the cooling system with clean water and a neutralizing solution until draining water is clear. Clean and install all drain plugs and/or close the drain valve. Sodium Carbonate crystals at a rate of 250 grams per 40 liters of water (1/2 pound per 10 U.S. gallon of water) may be used as a neutralizer. Repeat Steps 1 thru 4 if necessary until the draining water is clear.Install Thermostat
Original thermostats may be used if they meet test specifications shown in the Service Manual and are not damaged or have excessive buildup of deposits.Caterpillar engines incorporate a shunt design cooling system and require operating the engine with a thermostat installed. If the thermostat is installed wrong, it will cause the engine to overheat.
Inspect gaskets before assembly and replace if worn or damaged. The thermostats can be reused if they are tested and meet the test specifications in the Service Manual.1. Install a new seal in the thermostat housing and install a new thermostat. Install a new gasket in the thermostat housing on the engine cylinder head.2. Install the cooling system connections and tighten the hose or piping clamps.Fill
All water is corrosive at engine operating temperature. If using standard type antifreeze, the cooling system should be protected with cooling system conditioner at all times. Use Caterpillar liquid cooling system conditioner to treat the coolant
