- Remove the steering shaft. Refer to Disassembly and Assembly, "Steering Shaft - Remove and Install".
- Allow the coolant in the cooling system to cool in order to prevent personal injury. Remove the radiator filler cap slowly in order to relieve system pressure.
- Drain a small amount of coolant into a suitable container for storage or disposal. This will allow the coolant that is in the cab to drain back into the radiator. The heater hose does not have a quick coupler.

Personal injury can result from contact with refrigerant.
Contact with refrigerant can cause frost bite. Keep face and hands away to help prevent injury.
Protective goggles must always be worn when refrigerant lines are opened, even if the gauges indicate the system is empty of refrigerant.
Always use precaution when a fitting is removed. Slowly loosen the fitting. If the system is still under pressure, release it slowly in a well ventilated area.
Personal injury or death can result from inhaling refrigerant through a lit cigarette.
Inhaling air conditioner refrigerant gas through a lit cigarette or other smoking method or inhaling fumes released from a flame contacting air conditioner refrigerant gas, can cause bodily harm or death.
Do not smoke when servicing air conditioners or wherever refrigerant gas may be present.
Use a certified recovery and recycling cart to properly remove the refrigerant from the air conditioning system.
