Drain
Pressurized System: Hot coolant can cause serious burns. To open the cooling system filler cap, stop the engine and wait until the cooling system components are cool. Loosen the cooling system pressure cap slowly in order to relieve the pressure.
Note: The engine can have the ability to auto start. Ensure that the power supply is isolated before any service or repair is performed.
Stop the engine and allow the engine to cool. Turn the isolator keyswitch to the OFF position.
Loosen the cooling system filler cap slowly in order to relieve any pressure. Remove the cooling system filler cap.
Open the cooling system drain valve . If the cooling system is not equipped with a drain valve, remove the cooling system drain plugs. Note: Drain the engine coolant from the following positions. Rear of engine block, Bottom of the heat exchanger and the underside of the exhaust manifold. The exhaust manifold may have two drains. The exhaust manifold that is installed on a engine that has a MCS control panel will only have one drain. 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.
For information regarding the disposal and the recycling of used coolant, consult your Caterpillar dealer or consult Dealer Service Tools.Flush
