If you run a 1HZ Land Cruiser from 1990 to 1999, this Jayrad JR2045J radiator keeps the cooling side of your kit simple and sorted, with a 4-row core sized at 475 mm high, 525 mm wide and 38 mm thick for steady heat control when the wagon is loaded. Inlet and outlet necks both sit at 35 mm diameter, so your existing hoses line up without hunting odd sizes across town.

The core uses four rows within that 38 mm thickness, which increases coolant contact area without crowding fans or shrouds on HZJ75, HZJ78 and HZJ79 chassis rails. Manual-only spec means no built-in transmission cooler, matching crews who already run a separate unit for hard towing. Those 475 x 525 mm dimensions stick close to standard radiator footprints, so brackets, cowls and mounting rubbers stay where they should for touring duty.

Q: Does this radiator suit automatic transmission Land Cruisers?

No, this radiator suits manual transmission models only. The unit is specified without an integrated transmission cooler circuit. Automatic gearbox setups usually require an internal or external cooler. Check your existing radiator or cooler arrangement before choosing this manual-only core.

Q: Do I need to modify the fan shroud to fit this radiator?

No, the core dimensions of 475 mm height and 525 mm width are intended to match standard Land Cruiser shrouds for these models. Existing mounting points and shroud positions should line up. Always test-fit the shroud on the new radiator before bolting it into the vehicle to confirm clearance.

Q: Will this fit both tray and wagon versions of the HZJ series?

Yes, the radiator suits HZJ75, HZJ78 and HZJ79 models from 1990 to 1999, which covers common wagon and cab-chassis variants using the 1HZ engine with manual transmissions. The key is to match the engine code, year range and manual box configuration. Measuring your old core against 475 x 525 x 38 mm adds an extra fitment check.

Q: What hoses should I use with this radiator?

Use hoses sized to suit 35 mm inlet and 35 mm outlet necks. Most aftermarket and OEM hoses for 1HZ-powered HZJ75, HZJ78 and HZJ79 manual models are built around this diameter. Inspect existing hoses for age cracks or swelling and replace them at the same time as the radiator for a more reliable cooling setup.
