Product Overview

Summary: This Transmission Cooler Installation Safe Operating Procedure provides a clear, step-by-step method for safely fitting and commissioning transmission coolers on light and heavy vehicles in Australian workplaces. It helps workshops and fleets protect workers, prevent vehicle damage, and maintain WHS compliance while improving transmission performance and reliability.

Installing an auxiliary transmission cooler involves working under vehicles, routing hoses near hot exhaust components, handling pressurised transmission fluid, and interfacing with electrical systems for thermo fans and monitoring. Without a structured procedure, these tasks can expose workers to burns, crush injuries, fluid injection, slips, and environmental contamination, as well as create long-term reliability issues for vehicles. This Transmission Cooler Installation SOP provides a comprehensive, WHS-aligned method that standardises how your team assesses, installs, tests, and documents every cooler installation across cars, 4WDs, light commercials, trucks and mobile plant.

The document sets out a logical workflow from pre-job planning and vehicle isolation, through safe lifting and support, to hose routing, mounting, leak testing and final inspection. It integrates hazard identification and control measures at each step, including PPE, lock-out/tag-out for mobile plant, hot work considerations, and spill control. By implementing this SOP, workshops and fleet operators can reduce rework, avoid warranty disputes, and demonstrate due diligence under Australian WHS law, while ensuring that every installation is safe, consistent, and traceable.

Key Benefits
