The 2021 Ford Ranger we have here has the 2.3-liter EcoBoost turbocharged four-cylinder engine mated to a 10-speed Ford designed and built automatic transmission and this one is equipped with four-wheel drive. It’s rated at 270 horsepower and has 310 pound-feet of torque.
It features an aluminum block and head, dual overhead cams with variable cam timing and direct fuel injection. A twin-scroll turbocharger featuring an electronically controlled wastegate is mounted directly to its head which features an integrated exhaust manifold.
Following the airflow, the intake charge starts at a snorkel at the top of the radiator on the passenger side and flows into a large air filter box. From there it travels directly to the twin-scroll turbocharger mounted low on the passenger side of the engine.
From there the air travels down underneath to an air-to-air intercooler mounted behind the front bumper and ahead of the main cooling radiator. The air then travels back up to the driver side of the engine to a drive-by-wire throttle body and into the composite plastic intake manifold.
On top of the engine you can see the four spark-plug coil packs visible surrounded by the composite plastic valve cover. The majority of the direct fuel-injection componentry is hidden underneath, exposed only is the high-pressure fuel regulator at the rear of the engine.
Servicing the Ford Ranger EcoBoost is relatively straight forward. Of note is the fact that there is a conventional engine mounted cooling fan so you should never operate and work under the hood with the engine running.
The coolant reservoir is located at the passenger side rear of the engine compartment near the fire wall. Ahead of it is the air-filter box and just to the front of that is the windshield washer fluid reservoir. Checking the engine oil and filling it is done front and center at the top of the engine.
The engine oil filter can be accessed from underneath the truck. Because the 10-speed automatic transmission is a sealed unit not encouraging your servicing and maintenance there is no dipstick or filler cap for it under the hood. Additionally there is no power steering fluid reservoir here as the Ranger has electric power steering.
Checking and filling brake fluid is done at the expected location at the driver side firewall. While the Ranger uses a traditional brake master cylinder and booster, the ABS control unit is located also just to the side of it.
The 12-volt battery is located just forward of the brake system and the high-current fuse box is adjacent to it. Additionally, this truck has the Tremor package with the upfitter switches and thus has an extra fuse box located just behind the headlamp on the driver side.
The main low-current fuse box for interior and consumer grade circuits can be found inside the cab, behind a cover under the headlight switch on the driver side.
