CAT Skid Steer Loader 236D

Warning: Pressurized system: Hot coolant can cause serious burn. To open cap, stop engine, wait until radiator is cool. Then loosen cap slowly to relieve the pressure.

NOTICE: Mixing ELC with other products will reduce the effectiveness of the coolant. This could result in damage to cooling system components.

Note: The machine was shipped from the factory with Extended Life Coolant (ELC) in the cooling system.

Drain the coolant whenever the coolant is dirty or whenever the coolant is foaming.

Air Conditioner Condenser - Clean

Personal injury can result from air pressure.

Personal injury can result without following proper procedure. When using pressure air, wear a protective face shield and protective clothing.

Maximum air pressure at the nozzle must be less than 205 kPa (30 psi) for cleaning purposes.

The air conditioner condenser is attached to the engine access door.

Note: Blow compressed air through the core in the opposite direction of air flow to clean condenser.

Single Level Suspension (SLS) undercarriage

Dual Level Suspension (DLS) undercarriage

Warning: Personal injury can result from hydraulic oil pressure and hot oil. Hydraulic oil pressure can remain in the hydraulic system after the engine has been stopped. Serious injury can be caused if this pressure is not released before any service is done on the hydraulic system. Make sure all of the attachments have been lowered, oil is cool before removing any components or lines. Remove the oil filler cap only when the engine is stopped, and the filler cap is cool enough to touch with your bare hand.

Start the engine and allow the engine to run for at least 15 seconds to recharge the accumulator.

Stop the engine. Keep the armrests in the LOWERED position. Turn the engine start switch to the ON position. Push the parking brake switch.

Move the electrohydraulic controls through all the positions.

Toggle the auxiliary switch multiple times.

Turn the engine start switch to the OFF position. The pressure in the hydraulic system has now been released.

Note: Some hydraulic lines on the downstream side of the accumulator may still contain pressurized oil. Use caution when you disconnect these hydraulic lines.

Cooling System Coolant Extender (ELC) - Add

When a Cat Extended Life Coolant is used, an extender must be added to the cooling system periodically.

Open the engine access door and raise the radiator guard. Refer to Operation and Maintenance Manual, “Access Doors and Covers”.

Note: The radiator cap may be located either on the left side of the radiator (C3.3B and C3.8 engines) or the right side of the radiator (C2.2 engine).

Slowly loosen the radiator cap in order to relieve system pressure. Remove the radiator cap.

If necessary, drain enough coolant from the radiator in order to allow the addition of the coolant additive.

Add 0.17 L (0.18 qt) of cooling system additive.

Inspect the radiator cap and the gasket. If the cap or the gasket is damaged, replace the cap. Install the radiator cap.

Check the coolant level in the sight gauge on the radiator. Maintain the coolant level to the top of the sight gauge with the radiator in the LOWERED position.

Diesel Exhaust Fluid Filter - Replace

Ensure that the engine is stopped before any servicing or repair is performed.

Ensure that fluids are contained during performance of inspection, maintenance, testing, adjusting, and repair of the product.

Be prepared to collect the fluid with suitable containers before opening any compartment or disassembling any component containing fluids.

Dispose of all fluids according to local regulations and mandates.

The DEF filter is located on the left side of the machine under the cab. Tilt the cab upward.

Remove the black plastic cover and then diesel exhaust fluid (DEF) filter assembly.

Install new DEF filter. Replace DEF filter cap.
