The Jayrad JR2023J radiator slots into Toyota Hilux RN85 and VZN130 models from 1989 to 1992 with a core size of 400 by 527 millimetres, so it lines up well with factory airflow. A 28 millimetre core thickness gives decent coolant volume for towing or sand work without choking the fan. Inlet and outlet diameters at 35 millimetres line up with common Hilux hoses, so you can get out there without chasing odd fittings.

Inside the tanks you have an integrated transmission cooler, handy when you are dragging a camper or tools day after day. The 400 millimetre core height suits standard fan shrouds, which keeps pull across the fins consistent in slow going. The 527 millimetre width makes use of the full grille opening on these Hilux models. Overall dimensions and ports are laid out for straightforward replacement, a smart buy if you want known specs instead of guessing at universal gear.

Q: Does this radiator fit all engine options in the 1989–1992 Hilux RN85 range?

This radiator suits the RN85 and VZN130 Petrol/T C/B variants listed. Always match the core size of 400 x 527 x 28 mm and the 35 mm inlet and outlet to your original unit before purchase. Toyota offered different cooling setups across some markets. Checking part numbers or measurements against your existing radiator avoids mismatches and extra workshop time.

Q: Is there an integrated transmission cooler in this Jayrad radiator?

Yes, this radiator includes an internal transmission cooler. That suits automatic models that route transmission fluid through the radiator tank. The built-in cooler keeps the plumbing neat compared with separate external coolers. If your Hilux is manual, the ports can remain unused but should still be checked for correct blanking during install.

Q: Can this radiator handle towing or loaded touring work?

The core dimensions and integrated transmission cooler are suited to towing and touring within the vehicle’s rated limits. The 28 mm thick core holds reasonable coolant volume for long climbs. The 400 x 527 mm face area lets the fan and vehicle airflow do the heavy lifting. Keeping the rest of the cooling system in good shape still matters for heavy work.

Q: Do I need to modify the factory fan shroud or mounts?

The dimensions are specified to suit standard RN85 and VZN130 mounting layouts. The 400 mm height and 527 mm width are close to the original footprint. That helps the shroud sit correctly so the fan pulls air across the full core. Always dry-fit the shroud and brackets before filling with coolant to confirm clearances and fixings.

Suits Toyota Hilux RN85 and VZN130 Petrol/T C/B models built between 1989 and 1992. Designed as a replacement radiator assembly using existing factory mounting points and hose positions for these models. Check core dimensions of 400 mm height and 527 mm width and 35 mm inlet and outlet diameters against the original radiator before installation. Professional installation is recommended to ensure correct connection of the integrated transmission cooler.
