This Jayrad JR2131J radiator slots into Toyota HiAce RZH vans with the 2.4L auto driveline from 1998 to 2005 and keeps the temperature in check on long runs. The core sits at 500 mm high and 395 mm wide so it fills the factory opening without fouling fans or shrouds. A 36 mm thick core gives enough coolant volume for loaded work vans pulling weight up long highway climbs.

The inlet and outlet necks sit at 35 mm so your existing HiAce hoses hook straight back on without drama. An internal transmission cooler is built into the tank so the auto fluid stays controlled without extra plumbing hanging under the van. Mount points line up with standard brackets so the gear drops into place like the original unit. For a HiAce that needs to get out there day after day this radiator is a smart buy.

Q: Does this radiator fit manual transmission HiAce models?

This radiator is specified for automatic transmission RZH HiAce models. Manual models often use a different configuration without an internal transmission cooler circuit. If a manual is fitted, the transmission cooler ports may not be required. Check your existing radiator part number and mounting layout before ordering.

Q: Do I need new hoses to install this radiator?

The inlet and outlet necks on this radiator are 35 mm, which match standard HiAce RZH hose sizing. In many cases existing hoses will physically fit these necks. However, old hoses can harden or crack when removed. Replacing worn hoses during radiator changeover is good practice for long term reliability.

Q: Is coolant included with the radiator?

No, coolant is not included with this radiator. You will need to supply the correct type and volume of coolant specified for your Toyota HiAce. Fresh coolant helps protect the new core from internal corrosion. Always bleed the cooling system properly after refill to avoid hot spots.

Q: Does the radiator come with a cap or sensors?

This listing covers the radiator assembly only. Radiator caps, fan switches, and temperature sensors are typically reused from your original setup or purchased separately if required. Inspect existing components for wear or damage during installation. Replacing tired caps and switches can prevent future overheating issues.

• Suits Toyota HiAce RZH with 2.4L engine and automatic transmission built between 1998 and 2005
• Radiator includes provision for integrated transmission cooler for automatic models
• Fitment requires transfer of original caps mounts and hoses from existing cooling system
• Professional installation recommended to ensure correct coolant level and hose alignment
