This Jayrad radiator drops into Jeep Wrangler JK petrol models from 2007 on with 3.6 L or 3.8 L engines, so you can tackle long hauls without watching the temp needle climb. A core size of 558 mm high by 508 mm wide and 26 mm thick handles low-range crawling, sand work and highway stints. The 38 mm inlet and outlet keep things matched to factory hoses on both auto and manual setups.

The end tanks carry transmission cooler provision to suit JK petrol models that run an external oil cooler, which keeps the driveline happier on hot days and steep climbs. Tube and fin layout across the 558 x 508 mm core is all about decent airflow and shedding mud and seed build-up. The overall package is a smart buy for anyone wanting proven cooling gear under the bonnet before they get out there again.

Q: Does this radiator suit both automatic and manual Jeep Wrangler JK petrol models?

Yes, it suits both. This Jayrad radiator is specified for Jeep Wrangler JK petrol models from 2007-on with either automatic or manual transmissions. The core dimensions and hose sizes match the factory layout on both gearbox options. That means the existing 38 mm hoses can be reused if they are in good condition. Always check your VIN and engine size to confirm compatibility before ordering.

Q: What engine sizes is this radiator compatible with?

It suits 3.6L and 3.8L petrol engines. The listing clearly notes compatibility with 3.6 litre and 3.8 litre Jeep Wrangler JK petrol engines from 2007-on. These engines share the same basic cooling layout, so the 558 mm by 508 mm core and 38 mm necks line up correctly. If your Wrangler runs a diesel engine, this radiator will not be the right fit. When in doubt, match the OEM part number with your current unit.

Q: Does this radiator include a transmission cooler provision?

Yes, it includes transmission cooler provision. The specifications state that the radiator features a trans cooler. On JK petrol models, that means there is provision to route transmission fluid through the radiator assembly as part of an external oil cooler arrangement. This helps manage gearbox temperatures on climbs and when towing. Always reconnect transmission lines carefully and refill fluid to the correct level after installation.

Q: Are new hoses or caps supplied with this radiator?

No, it is supplied as the radiator assembly only. The supplied information lists just the radiator and does not mention hoses, caps or mounting hardware. Plan to reuse your existing hoses, clamps and cap if they are still serviceable, or purchase replacements separately. Inspect all rubber parts for cracks or swelling during the changeover. Fresh coolant and good hoses will help the new core perform at its best and reduce the risk of leaks.

Suitable for Jeep Wrangler JK petrol models with 3.6L or 3.8L engines from 2007-on, including automatic and manual transmissions. Radiator features trans cooler provision for vehicles with an external oil cooler configuration. Fitment requires transfer of original hoses, clamps and mounting hardware from the existing radiator. Professional installation is recommended to ensure correct coolant level, hose alignment and fan shroud clearance.
