Dual Coolant Reservoirs: Do Not Overlook the Intercooler Loop
The 2.0L Turbo 8AR-FTS engine features two completely separate cooling systems: one for the engine block/heater core and a second dedicated low-temperature loop for the liquid-to-air turbo intercooler. When flushing coolant, both systems must be drained and bled individually. An air pocket in the intercooler loop will cause intake air temperatures to spike, triggering boost reduction without showing an engine overheating warning on the gauge cluster.
Electronic Parking Brake (EPB) Service Mode Warning
The rear brake calipers are equipped with integrated electronic parking brake servo motors. NEVER use a traditional C-clamp or caliper press tool to force the rear piston in without first putting the EPB system into Service Mode (retraction mode) using a scan tool↗ (such as the Autel AP200↗). Forcing the piston mechanically will strip the internal plastic gears, requiring an expensive $700+ caliper replacement.
Turbo Spark Plug Service Interval: 40,000 Miles
Because the 8AR-FTS runs high cylinder pressures with dual injection (direct D-4S and port), spark plug degradation is much faster than on naturally aspirated V6 models. Factory recommendation is replacement every 40,000 miles (64,000 km) using Denso FK20HBR8 plugs. The gap is tight at 0.031 in (0.8 mm); do not regap Iridium plugs by hand to avoid damaging the fine electrode tip.

❓ Frequently Asked Questions
How much oil does a 2015-2021 Lexus NX 200t / NX 300 take?
With a new oil filter, the 2.0L Turbo 8AR-FTS engine takes 5.2 US quarts (4.9 liters) of SAE 0W-20 full synthetic engine oil. Without replacing the filter, it takes 4.9 US quarts (4.6 liters).
Why does the Lexus NX 200t/300 have two coolant reservoirs?
The NX 200t/300 utilizes a water-to-air intercooler for the turbocharger. To keep intake air temperatures as low as possible, Toyota engineered an independent cooling circuit with its own radiator, electric water pump, and coolant reservoir separate from the main engine cooling system.
How do you retract the rear brake calipers on a Lexus NX?
Because the NX utilizes an Electronic Parking Brake (EPB) with an electric actuator on the caliper, the piston cannot be forced back with a C-clamp. You must place the EPB into 'Service Mode' using a bidirectional scan tool (like the Autel AP200) to retract the internal spindle before pushing the piston in.
What is the spark plug change interval for the NX 200t/300?
Lexus specifies spark plug replacement every 40,000 miles (64,000 km) for the 2.0L Turbo engine due to higher cylinder combustion pressures and thermal stress from turbocharging.
