Q: Does this radiator fit all Toyota Hilux models from 2005–2010?

No, it suits Toyota Hilux GGN V6 4.0L manual models only. Other engine codes or automatic transmissions can run different radiator dimensions and fittings. Always check your VIN and engine code before ordering. If your Hilux is diesel or a different petrol variant this unit is unlikely to match.

Q: What core size should I check against my existing radiator?

You should confirm a core size of approximately 525x651x16 mm. Measure only the finned core area excluding the plastic end tanks. Matching core height and width is important for shroud clearance. Matching thickness helps keep fan and mounting hardware aligned.

Q: Are the hose connections the same as the factory radiator?

Yes, the inlet and outlet diameters are both 34 mm. This matches the factory hose sizing on the Hilux GGN V6 4.0L manual. Reusing your existing hoses is possible if they are still in good condition. Many owners choose to fit new hoses at the same time for peace of mind.

Q: Does this radiator include an internal transmission cooler?

Yes, it includes an integrated transmission cooler circuit in the tank. This cooler supports the driveline cooling layout used on the specified Hilux models. Always reconnect the transmission lines carefully and bleed the system as per your workshop manual. Using the correct transmission fluid type and level is critical for long-term reliability.
