Engine Block Heater: Description and Operation

PURPOSE
The optional engine coolant heater (RPO K05) is designed to warm the coolant in the engine block area for improved starting in very cold weather (-29°C/-20°F). The use of the coolant heater helps reduce fuel consumption when a cold engine is warming up. The engine coolant heater coil is rated at 600 watts. The engine coolant heater coil operates from 110 volt AC external power supply. The coolant heater is required in Canada on a engine.

OPERATION
The coolant heater consists of a small electrical heating element inserted through the left rear water jacket hole in the engine block. This heating block is precisely machined. The heating block uses a rubber O-ring to seal the coolant passage. A weather shield on the cord is provided to protect the plug when not in use.
