300 Series Landcruiser Engine and Transmission Protection

Why has HPD developed this Heat Exchanger?

It has become widely known that the 300 Series Landcruiser loses considerable power when the going gets tough, especially during towing in hot weather.

The two small side-mounted factory heat exchangers behind the front bumper receive poor airflow. In hot conditions, they struggle to reduce coolant temperatures that circulate through the water-to-air intercooler. This results in higher intake temperatures, higher overall engine temperatures and power loss, due to the ECU performing what it's programmed to do to protect the engine.

Positioned in the flow for more go

HPD's Heat Exchanger acts as an auxiliary to the two factory heat exchangers and is positioned behind the grille to receive maximum airflow to effectively reduce coolant temperatures that pass through the water-to-air intercooler.

How well does it work?

Development vehicle owner Brad reported that after the HPD Heat Exchanger, Transcooler and Catch Can was fitted, when towing his 3.2 tonne caravan up Accommodation Hill, Sturt Highway South Australia, he experienced no power loss, instead the vehicle was still accelerating. On a previous trip, in similar weather conditions, he experienced considerable power loss.

This unit, features our infamous Bar & Plate core optimised for fluid cooling as well as CNC machined billet alloy end tanks. This Heat Exchanger unit has been proven to reduce intercooler coolant temperatures by 20°C. We observed negligible loss of power in hot conditions during vehicle testing, on both the dyno and on-road testing.

With only OEM heat exchangers, after 8 back-to-back dyno pulls, power loss was 22kw

With hpd heat exchanger fitted, after 8 back-to-back dyno pulls, power loss was only 8kw

Easy 45min to 1 hour install time & lower cost!

At a significantly lower price of competitors products, this premium quality heat exchanger kit is designed for ease of installation, with no drilling and only very minimal trimming of plastic shrouds required.

HPD's extremely popular Transcoolers are proven to reduce transmission destroying temperatures.

During road testing, we saw an average of 24.47°C drop in trans fluid temperatures.

HPD transcooler's highly durable Bar and Plate core offers more than twice the surface area of most competitor’s transmission cooler units for superior cooling performance. Its durability is a result of its construction from solid sections of aluminium bar, sandwiching rows of fin and braised in a furnace to form a highly robust, solidly bonded unit.

All HPD products are supplied as a kit and include everything you need for a neat, factory-look installation, including every nut bolt washer. HPD Kits are also designed to fit as easily as possible with the least amout of modifications to your vehicle.

This Australian made premium quality catch can kit features a stunning billet alloy intake adaptor elbow (replacing the factory plastic unit) in addition to HPD's famous billet alloy catch can.

HPD diesel catch cans are one of the few on the market that do not vent harmful vapours into the atmosphere. This makes them fully compliant with all Australian emissions regulations and design rules in all states & territories.

No expensive or time-consuming repairs from seals and gaskets failing due to excessive crank case pressures. HPD Catch Cans don’t develop excessive crank case pressure as our 8-layer stainless steel mesh filtration system does not clog up like paper or fabric cartridges of other systems. Our Catch Cans are not reliant on valves or bypasses that can commonly fail in real world applications.

You won’t have the hassle of buying and replacing filter cartridges on a HPD catch can. Our filtration system is fully cleanable.
