About Engine Air Intake Heater Relay

The engine air intake heater relay is a switch that electronically opens and closes circuits. The relay is vital when it comes to controlling a single circuit that is utilized to power the engine heater grid.

Engine air intake heater relay function

The heater grid relay has the task of opening and closing contacts in the circuit to start up the operation of the heater grid. The heater grid is placed right in the middle of the air horn and the intake manifold. The heater grid relay is a vital component of the operation because when the weather gets cold, the heater grid warms up the incoming air during the startup process to guarantee a quick start.

Common issues with a faulty engine air intake heater relay

A faulty engine air intake heater relay can lead to white smoke during cold starts, lengthy crank times, and difficulty starting during cold weather.
