Q: Will this fit my 1KD Prado?

A: Yes — fits Prado 120 (2003-2009) and Prado 150 (2009-2015) with 1KD-FTV engines.

Q: Why upgrade from the factory oil cooler?

A: Factory oil coolers are prone to thermal cracking, leading to coolant/oil contamination. FuseTech's billet aluminum construction eliminates this failure point while improving cooling performance.

Q: How much cooler will my oil run?

A: Customers see up to 10-15°C reduction in oil temperatures under load, especially when towing or off-roading.

Q: Is this a direct replacement for the factory cooler?

A: Yes — 100% direct bolt-on. Uses factory mounting points and coolant connections. No modifications required.

Q: What's included in the kit?

A: Complete kit includes the billet oil cooler, all required Gaskets to mount the cooler to the housing, and an oil cooler housing gasket to reseal the housing to the block.

Q: Can I install this myself?

A: If you're comfortable working with coolant systems, yes. Professional installation is recommended to ensure proper seal installation and coolant system bleeding.

Q: Will this work with a tuned 1KD engine?

A: Absolutely! In fact, it's highly recommended for tuned engines that generate more heat. Superior cooling helps protect your investment.
