F2143 Force HEX SOC. HD SCREW, 1/4 - 20 X 1 S.S.

At Operating Temperature, engine coolant is hot and under pressure.Steam can cause personal injury.Check coolant level ONLY when engine is stopped and radiator cap is cool enough to touch with your hand.Remove filler cap slowly to relieve pressure.Cooling System Conditioner contains alkali. Avoid contact with skin and eyes to prevent personal injury.
1. Loosen radiator cap slowly to release pressure and remove filler cap.
If the engine is to be stored in, or shipped to, an area with below freezing temperatures, the cooling system must either be protected to the lowest expected ambient temperature, or drained completely.Never add coolant to an overheated engine, allow engine to cool first.Do not use Caterpillar Cooling System Conditioner or Coolant Conditioner Elements with Dowtherm 209 Full-Fill coolant.
2. Remove radiator drain plug. 3. Remove the engine block drain plug.
Use all cleaning solutions with care.
4. Install drain plugs. Fill system with a commercially available cleaning solution or 1 kilogram (2 lb.) Sodium Bisulfate (NaHSO4) per 40 liters (10 U.S. gallons) water.5. Start and run for 1/2 hour. Stop engine and drain cleaning solution.6. Flush system with clean water until draining water is clean. Do not run engine while flushing.7. Install all drain plugs. Fill system with neutralizing solution or 250 grams (1/2 lb.) Sodium Carbonate Crystals (Na2CO H2O) per 40 liters (10 U.S. gallons) water.8. Start and run engine for 10 minutes. Stop engine and drain neutralizing solution.9. Flush system with clean water, until draining water is clean. Do not run engine while flushing.10. Install all drain plugs.11. Fill engine with clean water. Run the engine for 10 minutes and drain.Repeat until drained water is clean.12. Add 1 liter (1 quart) of Caterpillar Cooling System Conditioner, or equivalent, for each 30 liters (8 gallons) of cooling system capacity so cooling system will have a 3% to 6% concentration of conditioner.Most systems will require 2 liters (2 quarts) of conditioner at initial fill and .50 liters (1 pint) "Every 250 Service Hours."13. Mix antifreeze and water to provide protection to the lowest expected ambient temperature.14. To help avoid air locks, add coolant slowly, at 19 liters (5 U.S. gallons) per minute or less.Air Induction System-Changing Elements
Single Stage Air Cleaner
Service the air cleaner with the engine stopped.
Service the air cleaner when the red plunger in the indicator locks in the visible position. 1. Remove the air cleaner cover and element. 2. Cover the turbocharger inlet opening. 3. Clean the inside of the air cleaner cover and body.4. Inspect the replacement element for damage and dirt.5. Remove the covering from the turbocharger inlet opening.6. Install a clean undamaged element. 7. Install the air cleaner cover. 8. Reset the service indicator.Two Stage Air Cleaner
1. Loosen the clamping bolt on the lower body.2. Remove and empty the dust collector cup. 3. Loosen the clamping bolt on the upper body. 4. Remove the lower body and clean the tubes from both ends.5. Inspect the seals between the lower body and the dust collector cup, and between the lower body and upper body. Install new seals if necessary. 6. Install the lower body to the upper body and tighten the retaining clamp. 7. Install the dust cup and tighten the retaining clamp.Installing Replacement Filter Elements For Two Stage Air Cleaner
1. Remove the cover.2. Remove the inner cover and filter element. In cold weather, a stuck inner cover may be removed by warming the air cleaner cover to 21-24°C (70-75°F)3. Clean all parts of the air cleaner.4. Inspect the replacement element for damage and cleanliness.5. Install a clean undamaged element, inner cover, and wing nut. Tighten the wing nut.6. Install the cover.Cleaning Air Cleaner Elements
When using pressure air, wear face shield and protective clothing. Maximum air pressure for cleaning purposes must be 205 kPa (30 psi).
When cleaning with pressure water, use 280 kPa (40 psi) maximum pressure to prevent element damage.
Do not clean elements by bumping or tapping them on hard objects.Inspect an element after cleaning. Do not use an element with damaged pleats, gaskets or seals.
Have spare elements on hand to use when cleaning used ones.Dry type air cleaner elements can be cleaned with either pressure air, water or detergent.Pressure Air - 205 kPa (30 psi) Maximum
1. Direct air inside along length of pleats. 2. Direct air outside along length of pleats. Direct air inside along length of pleats. Inspect.Water - 280 kPa (40 psi) Maximum
