Whether it’s a trailer, boat, caravan or camper, hauling that extra weight behind your vehicle means the engine has to work harder

Typically, factory-fitted cooling systems will need some extra help to cope with the increased heat generated when the engine and transmission are under load.
The payload and frequency of towing will dictate how much you need to upgrade your vehicle’s cooling system.
Another important factor is the operating environment. Hilly terrain or surfaces such as dirt, sand and mud will require slower travelling speeds which reduces air flow.
Adrad has the following advice on options for enhancing cooling performance that can be applied in isolation or combinations to suit your needs.

Adrad says while it may seem odd, a less expensive coolant can deliver increased cooling. Testing shows that Adrad corrosion inhibitor coolant can transfer heat up to 40 percent more effectively than a traditional 50 percent glycol coolant.
The high water content of corrosion inhibitor makes it thermally more efficient, however this practice is not suitable for sub-zero environments. Adrad’s Australian made corrosion inhibitor coolants are available in traditional and organic formulations.

Radiator and Intercooler
Depending on the age and service history of the vehicle, a new OE quality radiator or intercooler may be enough to manage infrequent or light towing duties.
Upgrades can range from heavy duty radiators with extra rows up to custom high performance alloy radiators and intercoolers for optimum cooling. Adrad says it has a wealth of experience in this area (along with Australia’s largest selection of radiators) and can provide you with great advice.

Transmission Cooler
An auxiliary transmission oil cooler may often be fitted as part of a “towing pack.” Adrad says this indicates that the standard oil cooler is unlikely to cope with heavy work and upgrading this oil cooler will improve performance.
Adrad offers the Dana Tru-Cool range of universal oil coolers which feature several sizes and performance options.

More air flow means better cooling. Adrad offers a selection of high performance fans from Spal and Maradyne that are designed for long life, durability and harsh environments.
The fan motor is encased in a fully-sealed housing that is 100 percent dust and waterproof. Adrad says their high-quality engineering and construction deliver proven performance to exceptional levels on the road, the race track and even in extreme off-road conditions.
These products are all available across Australia and are supported by Adrad’s national warranty and distribution network.
