Coolant Heater (LX5)

WARNING: This page is about a different car, the 2002 Oldsmobile Aurora and 2001 Oldsmobile Aurora. However, it is still accessible from the selected car via links, so may be relevant.

The optional engine coolant heater (RPO K05) consists of two electrical heating elements fastened to the left and right sides of the engine block. These heating blocks are precisely machined to fit the engine block area. Each heating element is rated at 300 watts and supplies 1025 Btu/hr. The engine coolant heater operates using 110 volt AC external power and is designed to warm the coolant in the engine block area for improved starting in very cold weather -29°C (-20°F). The coolant heater helps reduce fuel consumption when a cold engine is warming up. The units are equipped with a detachable AC power cord. A weather shield on the cord is provided to protect the plug when not in use.
