Here’s an in-depth look under the hood and under-body of the new Toyota Highlander!


The Toyota Highlander uses a 2GR-FKS 3.5L engine and an conventional 8 speed automatic transmission. In this video, we go through the layout under the hood and underneath each subsystem to see how it was designed, laid out and how difficult it would be to repair or maintain for owners looking to buy the Highlander in the longer term.


Overall, the engine’s layout is straight forward with its tried and true D4S dual injection system, carbon buildup should not be an issue. Maintaining the cooling system however, requires the removal of a lot of many other components, such as the entire front clip of the vehicle for the radiator, or the entire engine transaxle assembly to access the water pump and thermostat! Underneath, the Toyota Highlander gets a way using an all steel structure, including a fully boxed in frame and an all steel suspension.


To conclude, the Highlander is a reasonable entry into the SUV market with expected resale and reliability better than average, though there are some maintenance items that are questionable and the lack of innovative design or materials underneath demonstrates Toyota has funnelled development costs elsewhere.
