2024-2025 Alfa Romeo Tonale / Dodge Hornet Aux Pump TSB Guidance

Introduction to the GPOP - Issue Review System

This document, identified as GPOP - Issue Review System (document number 9100503, revision C), is a manufacturer communication dated February 25, 2025. It serves as an internal directive for technicians working on 2024-2025 Alfa Romeo Tonale and Dodge Hornet vehicles. Its primary purpose is to ensure proper diagnostic and repair procedures are followed, specifically concerning the auxiliary pump, before any parts are replaced.

Understanding the Auxiliary Pump

An auxiliary pump, often referred to as an Aux Pump, is a component within a vehicle's electrical system designed to circulate fluids. Depending on the vehicle's specific design and powertrain, this pump might support various systems such as engine cooling, transmission cooling, or heating, ventilation, and air conditioning (HVAC) systems. A malfunction in the auxiliary pump can lead to issues with these critical systems, potentially affecting vehicle performance, efficiency, or passenger comfort.

Key Directive for Technicians

This manufacturer communication provides a crucial instruction regarding the auxiliary pump for the affected vehicles. It explicitly states: "Before replacing any parts, please refer to TSB 08-045-24 REV. C and TSB 08-044-24 REV. C." This directive emphasizes that a simple part replacement may not be the correct first step in resolving an auxiliary pump issue. The referenced Technical Service Bulletins (TSBs) are intended to guide technicians through comprehensive diagnostic processes to accurately identify the root cause of any reported problem.

Importance of Consulting TSBs

For service technicians, adhering to this guidance is paramount for accurate and efficient repairs. Consulting TSB 08-045-24 REV. C and TSB 08-044-24 REV. C ensures that the latest manufacturer-approved diagnostic and repair methods are utilized. These TSBs likely contain detailed diagnostic steps, specific test procedures, updated repair instructions, or information about particular conditions that could lead to auxiliary pump concerns. Following these bulletins helps prevent misdiagnosis, avoids unnecessary part replacements, and reduces the likelihood of repeat service visits for the same issue related to the Alfa Romeo Tonale Aux Pump or Dodge Hornet Aux Pump.

Affected Part Numbers

The manufacturer communication specifically lists two part numbers associated with the auxiliary pump that are subject to this guidance: 68457132A$ and 68675216A$. Technicians should be aware of these part numbers when diagnosing or considering replacement of auxiliary pump components. The directive applies to any situation where these parts might be considered for replacement.

What This Means for Owners

If you own a 2024 or 2025 Alfa Romeo Tonale or Dodge Hornet and experience issues that you suspect are related to the auxiliary pump, it's important to take your vehicle to an authorized service center. While this document is primarily for technicians, understanding its content can help ensure your vehicle receives the most accurate and effective repair. You can mention manufacturer communication 9100503 and the referenced TSBs (08-045-24 REV. C and 08-044-24 REV. C) to your service advisor. This helps confirm that your service center follows the latest diagnostic and repair procedures before any parts are replaced, especially if you are experiencing an Alfa Romeo Tonale Aux Pump problem.
