REMOVAL
There are several heater core plumbing configurations used on this model, depending upon the engine size and other optional equipment. These
engines have unique heater return plumbing on the engine for models with or without an optional engine oil cooler. There are also unique plumbing
configurations at the heater core for models with or without the optional rear heater and air conditioner. All models use a combination of formed steel
tubing and rubber hoses. In most cases, the rubber hose is secured to the steel tubing with a spring tension clamp.
WARNING: REFER TO THE APPLICABLE WARNINGS AND CAUTIONS FOR THIS SYSTEM BEFORE PERFORMING THE
FOLLOWING OPERATION.
1. Drain the engine cooling system. Refer to: "Engine, Cooling and Exhaust : Cooling System : Service and Repair" See: Engine, Cooling and

the hose to be removed. Release the clamp when it is OFF of the tube or nipple.
