This Jayrad radiator JR2823J is set up for Toyota Land Cruiser HZJ76, HZJ78 and HZJ79 with the 6-cylinder HDJ motor and manual box, so it drops into the 70 Series front end with a core footprint of 550 mm high by 583 mm wide. You get a 48 mm thick core, 42 mm inlet and 42 mm outlet, so the hoses line up and flow matches factory spec when you are hauling gear or heading remote.

A 28 mm breather port gives the cooling system the expansion space it needs when temps climb on long highway pulls in 40 degree days. The built-in transmission cooler section is ready for compatible driveline setups, keeping oil temps steadier when the Land Cruiser works hard. These dimensions suit standard HDJ manual configurations, so you can get out there knowing the cooling side matches the demands of Aussie touring and work use.

Q: Does this radiator fit all Toyota Land Cruiser 70 Series models?

No, it suits specific HDJ 6-cylinder manual variants of the 70 Series. It is listed for HZJ76, HZJ78 and HZJ79 models with the HDJ engine and manual transmission. Other engines or automatic transmissions may use different radiator dimensions and hose layouts. Always check your vehicle build plate and existing radiator measurements before ordering.

Q: What hose sizes does this radiator accept?

This radiator accepts hoses with 42 mm internal diameter on both inlet and outlet. Matching the 42 mm size helps maintain correct clamp pressure and coolant flow through the core. If your existing hoses differ from 42 mm, you may need new hoses sized to suit. Correct sizing reduces the risk of leaks at the tank connections.

Q: Is there a breather or overflow connection on this unit?

Yes, it includes a breather connection with a 28 mm diameter. This connection links to the overflow or expansion system and lets coolant move as it heats and cools. Using the correct 28 mm hose keeps the system pressure range stable. Always route the breather hose without kinks so flow stays consistent.

Q: Does this radiator include a built-in transmission cooler?

Yes, the radiator features an internal transmission cooler section. This cooler is intended for compatible driveline setups that route oil through the radiator. Using the integrated cooler helps manage oil temperature during towing or heavy use. Always confirm thread types and line routing on your specific vehicle before installation.

Suits Toyota Land Cruiser HZJ76, HZJ78 and HZJ79 70 Series models with 6-cylinder HDJ engine and manual transmission. Suits vehicles that require a radiator with 550 mm core height and 583 mm core width. Suits cooling systems that use 42 mm inlet and outlet hose connections. Includes built-in transmission cooler to suit compatible driveline setups.
