Keep your transmission and engine operating at their optimum temperature with the Davies Craig range of Transmission & Engine Oil Coolers. Designed to reduce automatic transmission fluid (ATF) and engine oil temperatures, our universal aluminium oil coolers help prevent overheating, improve lubrication and extend the service life of critical drivetrain components.
Whether you're towing a caravan, tackling off-road tracks, driving in heavy traffic or competing in motorsport, excessive heat is one of the leading causes of transmission and engine wear. Davies Craig Oil Coolers efficiently dissipate excess heat, helping maintain consistent performance and long-term reliability in demanding conditions.
Manufactured from lightweight aluminium and 100% pressure tested for quality and durability, the Davies Craig range includes solutions for passenger vehicles, performance cars, 4WDs, commercial vehicles and motorsport applications.
Choose from the economical Ultra-Cool® Tube & Fin range for everyday and heavy-duty applications, or the premium Hydra-Cool® Plate & Fin range for maximum cooling efficiency in high-performance, towing and extreme-duty environments.

The Transmission & Engine Oil Cooler Product Selection Guide will indicate when a Thermatic® Fan is recommended for your application.
Most transmission oil coolers are mounted in front of the radiator or air conditioning condenser to maximise airflow.
Measure the available installation area and record the following dimensions:
