The Koyorad radiator slots straight into Suzuki Grand Vitara JB and JT models with 2.0 litre or 2.4 litre engines from 08/2005 on and keeps coolant moving through a 450 by 690 by 16 millimetre core. You can take that Grand Vitara from the bush to the beach knowing the 34 millimetre inlet and outlet line up with factory hoses so the kit works with your existing cooling setup. This gear runs a 16 millimetre thick core so airflow from the front fans and grille does not choke up on slow climbs or sand work. The 450 millimetre height and 690 millimetre width match factory mounts which makes this radiator a smart buy when the old core clogs. Koyorad backs the setup with proven dimensions that handle Australian heat and towing loads without drama.

Q: Does this radiator fit automatic transmission Grand Vitara models?

This radiator is listed for manual transmission Suzuki Grand Vitara JB and JT models. The cooler layout and fittings on automatic versions can differ, so using the wrong unit may affect transmission cooling. Always match the transmission type to the original radiator. If your vehicle is automatic, confirm part numbers specific to auto models before ordering this gear.

Q: How can I confirm this radiator will match my existing Grand Vitara radiator?

Check your current radiator core height, width and thickness and compare them to 450 mm high, 690 mm wide and 16 mm thick. Measure the inlet and outlet neck diameters and confirm they are 34 mm. Also confirm your Grand Vitara is JB or JT series with a 2.0L or 2.4L engine built from 08/2005 onwards. Matching these details is the best way to avoid fitment surprises.

Q: Do I need new hoses when installing this Koyorad radiator?

New hoses are not strictly required if your existing hoses still seal well on 34 mm necks. Many owners replace upper and lower hoses at the same time because rubber can harden with age and heat. Fresh hoses reduce the chance of leaks on big trips. If the old hoses show cracks or swelling, replacement is a smart move while the system is already drained.

Q: Is this radiator suitable for towing and long-distance touring?

The radiator core size of 450 x 690 x 16 mm is similar to the original setup used in Grand Vitara JB and JT models. When the cooling system is in good condition and correctly filled, this size handles typical towing and highway use for these engines. Keeping the fins clean and the shroud and fan in place helps the radiator maintain performance. Regular coolant changes also support long-term reliability on touring trips.

Suitable for Suzuki Grand Vitara JB and JT models with 2.0L or 2.4L engines built from 08/2005 onwards with manual transmission. Check the existing radiator core size of 450 mm x 690 mm x 16 mm and inlet and outlet diameters of 34 mm to confirm compatibility. Installation should follow the factory Suzuki workshop manual for the JB and JT Grand Vitara cooling system. Reuse or replace hoses and coolant to match the 34 mm inlet and outlet diameter connections.
