Description and Purpose

The International / Navistar® Intake Manifold EGR Heater Relay (Part Number: 1845347C1) is a high-quality, new replacement relay designed to regulate the intake manifold heater system in diesel engines. This 12V SPST relay ensures efficient electrical switching, enabling proper engine warm-up and emissions control. Engineered for compatibility with various International, Navistar, and Ford vehicles, it features a robust electrical resistor design and a high current rating of 130A to withstand demanding conditions.

Why Replacement is Important

A malfunctioning EGR heater relay can lead to poor cold-start performance, increased emissions, and potential engine inefficiencies. Replacing a faulty relay ensures the proper operation of the intake manifold heater, preventing rough idling, excessive fuel consumption, and difficulty starting in cold weather. Timely replacement also protects other engine components from unnecessary strain and prolongs system longevity.

Impact on Vehicle Performance

This relay plays a crucial role in maintaining optimal intake air temperatures, ensuring smoother engine operation and reduced emissions. With a maximum ambient temperature tolerance of 125°C (257°F), it is built to handle extreme conditions. By delivering reliable power switching for the intake manifold heater, this relay contributes to improved fuel efficiency, lower emissions, and enhanced overall engine performance.
