Specifications

Why Install a Hydra-Cool^® Fan Combo?

Automatic transmissions generate extreme heat during heavy towing, steep climbs, stop-start traffic, off-road driving and commercial operation. In these demanding environments, natural airflow through a conventional transmission cooler is often insufficient to maintain optimum fluid temperatures.

The Davies Craig Hydra-Cool^® 30 Plate & 10" Slimline Thermatic^® Fan Combo (24V) provides continuous airflow through the cooler regardless of vehicle speed, ensuring maximum cooling efficiency under the toughest operating conditions. The combination of a high-capacity 30 Plate Hydra-Cool^® Dimple Plate & Fin Cooler and a powerful 10" Slimline Thermatic^® Fan helps improve transmission reliability, extend transmission fluid life and protect against costly transmission failures.

How to Select the Correct Transmission Oil Cooler

All Davies Craig transmission oil coolers are universal fit, making it easy to choose the right cooler based on the available mounting space rather than your vehicle's make or model.

Step 1 – Determine the Correct Cooler for Your Application

Use the Transmission & Engine Oil Cooler Product Selection Guide (below) to identify the recommended transmission oil cooler for your application. The guide considers factors such as:

• Vehicle type
• Transmission type
• Intended use and operating conditions

This will recommend the appropriate transmission oil cooler size for your application.

Step 2 – Is a Thermatic^® Fan Beneficial?

Some applications benefit from the addition of a Thermatic^® Electric Fan to provide consistent airflow through the oil cooler when natural airflow is limited.

A fan is recommended for applications including:

• Towing
• Motorsport or performance driving
• Off-road vehicles
• Remote-mounted oil coolers
• Low-speed or stop-start operation

The Transmission & Engine Oil Cooler Product Selection Guide will indicate when a Thermatic® Fan is recommended for your application.

Step 3 – Measure the Available Space

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:

• Width
• Height
• Available Clearance (Depth)

Step 4 – Choose the Largest Cooler That Fits

As a general rule, the largest transmission oil cooler that comfortably fits within the available space will provide the best cooling performance. A larger cooler offers greater heat dissipation, helping to maintain lower automatic transmission fluid (ATF) temperatures, particularly when towing, carrying heavy loads, driving off-road, or operating in hot conditions.

Step 5 – Compare Your Measurements

Once you have your dimensions, visit the Davies Craig Transmission Oil Coolers page and review the Specifications & Range table located approximately halfway down the page.

There you can:

• Compare each oil cooler's dimensions with your available mounting space.
• Select the largest cooler that can be installed without interfering with surrounding components.
• Choose from our Ultra-Cool^® Tube & Fin or Hydra-Cool^® Plate & Fin ranges to suit your application.
