This Jayrad JR8055J radiator is set up for Mitsubishi Triton MK and Challenger with the 2.8L diesel and manual box, so you can tackle long highway stretches and slow climbs without coolant temp dramas. The core stands at 500 mm high, 634 mm wide and 40 mm thick, giving plenty of surface area to dump heat when the ute is working with a load or camper on the back.

The inlet and outlet are both 35 mm, matching factory hose sizes so you keep the standard clamps and routing tidy. The tanks and core layout line up with manual transmission models that need a built-in cooler path, so you are not chasing odd fittings. It is smart buy cooling gear for Aussie heat, from coastal humidity to inland summer runs, and it drops into the standard support panel with familiar mounting points.

Q: Does this radiator fit automatic Triton MK models?

This specific JR8055J radiator is listed for manual transmission (M/T) Triton MK models. The tank and cooler layout suit the manual setup, and automatic versions often use a different transmission cooler arrangement. Always match the part number against your VIN and gearbox type. If you run an automatic, check for the correct Jayrad reference before ordering.

Q: What coolant should I use with this Jayrad radiator?

Use a quality coolant that meets Mitsubishi specifications for the 2.8L diesel engine. The correct coolant mix protects the alloy core and internal passages from corrosion. Always mix to the ratio stated on the coolant container. Flush the old coolant completely before refilling to avoid chemical clashes and sludge build-up.

Q: Do I need new radiator hoses when installing this unit?

You can reuse existing hoses if they are in good condition and still grip the 35 mm necks firmly. Many owners choose to replace upper and lower hoses during a radiator swap as preventative maintenance. Fresh hoses reduce the risk of splits on long trips. Inspect clamps and replace any that show rust or loss of tension.

Q: Is this radiator suitable for towing and outback touring?

The 40 mm core thickness and large 500 x 634 mm face area are well matched to towing and loaded touring in Australian conditions. Correct fan operation and shroud fitment are still critical for airflow at low speed. Combine this radiator with clean coolant and a healthy viscous fan hub. Regularly check for mud or seed build-up across the fins after off-road work.

Suits Mitsubishi Triton MK 2.8L diesel manual transmission models built between 2003 and 2006. Also suits compatible Mitsubishi Challenger variants using the same 2.8L diesel manual drivetrain. Fitment requires removal of the factory radiator and transfer of original hoses, fan shroud and mounting hardware where applicable. Check core dimensions of 500 mm height and 634 mm width and 35 mm inlet and outlet diameters against the existing unit before installation. Professional installation is recommended for correct coolant bleeding and transmission cooler connection.
