Exclusive to Adrad

Adrad says Dana is one of the most respected names in the global automotive industry for both aftermarket and original equipment products.
Adrad has secured the exclusive distribution of Dana’s Tru-Cool range of engine and transmission oil coolers in Australia. It says these aftermarket oil coolers are ideal for a variety of applications including trucks, vans, passenger vehicles and SUVs which are used for carrying heavy loads or towing duties.
Packaging for these coolers features the manufacturing name “Long” (owned by Dana), which was a Detroit-based parts manufacturer supplying America’s pioneer auto industry. Adrad says Tru-Cool oil coolers have been the preferred choice of US vehicle manufacturers and repairers, car enthusiasts and motorsport teams for decades.
Many vehicle manufacturers recommend fitting an auxiliary transmission oil cooler when adding a tow bar and typically will include one in their optional accessory ‘towing pack.’ Adrad says Dana Tru-Cool high-quality coolers are available in a selection of sizes and styles to suit all manner of vehicles and include Tru-Cool LPD (Low Pressure Drop) and Tru-Cool MAX high performance variants.
Installers can choose from 20 products depending on the size and performance requirements. All products in the range have installation kits featuring hoses, mounting hardware and fittings either already included or available separately. They carry a 12-month warranty which is supported by Adrad’s extensive nationwide network.
Featuring high strength brazed construction in either a stacked plate or fin and plate arrangement, Tru-Cool LPD products are said to deliver 30 percent more cooling and 15 times less flow restriction than provided by a traditional tube and fin design unit.
Adrad says vehicles which require superior cooling performance should opt for Dana’s Tru-Cool MAX unit. It explains these feature the same high strength brazed aluminium construction but offer double the cooling of the Tru-Cool LPD design.

The provided installation kit includes multiple fitting sizes and even a bypass to protect against cold start damage in severe winter conditions. The bypass will start to open at 82°C (180°F) and is fully open at 96°C (205°F).
Adrad explains that there are some essential rules to follow when selecting an oil cooler. It notes that as mentioned earlier, larger size is not always going to provide better cooling.
It suggests you take note of the hose diameter that supplies your existing oil cooler – this hose diameter is often larger for diesel engines as their high torque can place more load on the transmission. The hose fittings on your auxiliary oil cooler should not be smaller than the standard line diameter as this will restrict oil flow.
No matter which oil cooler is chosen, it needs to be correctly fitted and a good installation location is important to get the best cooling performance. When installing an auxiliary oil cooler into a vehicle, it needs to be exposed to ram air in order for effective cooling to be delivered. If a location with good air flow is not available, Adrad advises this can be overcome by adding an electric cooling fan to the oil cooler.
Adrad says you should avoid disconnecting the existing oil cooler in the radiator tank unless the vehicle manufacturer recommends it. Leaving this in place will not only allow the cooler to continue functioning, it also assists in pre-heating the transmission after start-up to help it reach operating temperature quickly.
Mounting the oil cooler in front of the radiator is an acceptable location and has the advantage of allowing the radiator fan to boost air flow at slow driving speeds. While it is true that heat released by the oil cooler will partly reduce the effectiveness of the radiator, it is also true that some of the heat load to the in-tank oil cooler is being removed, so overall the engine temperature should not increase by a significant amount, says Adrad.
Dana Tru-Cool oil coolers are available from Natrad, Adrad Radiator Experts and independent repairers across Australia.
