Q: Does this Koyorad radiator include an integrated transmission cooler?

It is useful for towing or slow work where fluid temperatures climb.

Q: Will this radiator fit manual transmission Prado GDJ150 models?

This radiator is specified for automatic models only. The built-in 250 mm transmission cooler and hose connections are arranged for an automatic gearbox. Manual models may use a different layout or part number. Always match your gearbox type and build date before ordering. If unsure, check your VIN with your mechanic.

Q: What measurements do I need to check before ordering?

Confirm vehicle series, build date, and hose sizes. Make sure your Prado is a GDJ150 built from 08/2015 onwards. Check that your existing top hose is 38 mm internal diameter and the bottom hose is 34 mm. Matching these specs helps confirm you are replacing like-for-like. When dimensions line up, installation usually goes more smoothly.

Q: Do I need new coolant when fitting this radiator?

Yes, new coolant is strongly recommended. Whenever a radiator is replaced the cooling system is drained. Fresh coolant mixed to the correct ratio protects the new core from internal corrosion. It also restores the proper boiling and freezing points. Follow Toyota guidelines or your mechanic’s recommendation for coolant type and mix.
