Q & A

What is the displacement and configuration of the Ranger 3.2 engine?
-The Ranger 3.2 engine has a displacement of 3,198 cc with a 5 cylinder in-line configuration and 20 valves.
What fuel system and drivetrain configurations are available on the Ranger 3.2?
-The Ranger 3.2 comes with a common rail direct injection diesel system, with 4x4 and 4x2 drivetrain configurations available, along with manual and automatic 6-speed transmissions.
Why does the Ranger 3.2 have 5 cylinders instead of 4?
-The 5 cylinder configuration was chosen to gain an additional 50 hp over the 4 cylinder variant, reaching 200 hp total output.
What causes the perception that these engines cannot be rebored?
-The large and complex mating surfaces on the block and cylinder head can be difficult for some machine shops' equipment to correctly machine.
What can cause issues if the engine peripherals are not serviced properly?
-Not replacing items like the turbo, injectors, injection pump etc. can lead to power loss, cylinder washing, oil blow-by, and other major issues.
What speeds do these trucks reach from the factory?
-The first generation Ranger 3.2 engines were limited to 130-140 km/h from the factory, even in Land Rover applications.
Why do these engines often require repairs?
-Improper or contaminated diesel fuel can cause injector issues leading to piston damage over time.
What maintenance helps prevent injector problems?
-Using a diesel injector cleaner twice a year helps keep injectors clean and operating properly.
How do these engines perform when properly maintained?
-When maintained correctly with quality fuels and fluids, these engines are quiet, powerful, and reliable.
What other Ranger models are available?
-The Ranger is also available with a smaller 2.2 liter 4 cylinder turbo diesel engine producing 150 hp.

😊 Introducing the channel and previewing Ranger 3.2 engine analysis

The host Nico introduces his channel about car engines and previews the analysis of the Ford Ranger 3.2 liter 5-cylinder TDCI engine. He mentions the engine's specifications, address some myths about it, and asks viewers if it is made or assembled in Argentina.

👷‍♂️ Describing the Ranger engine's robust construction and rectification challenges

Nico shows the engine's sturdy iron block, long cylinder walls, full crankshaft bedding, and aluminum cylinder head. He points out the wide machining surfaces that pose challenges for shops without proper equipment. A fractured connecting rod demonstrates modern engines can't be repaired like old ones.

10:02

💪 Explaining why Ranger engines often fail testing after machine work

Nico reveals most Ranger engine rebuilds fail because rebuilders overlook worn peripherals like the turbo, injectors, and injection pump. Even beautifully machined engines soon falter and blow gaskets when paired with faulty peripherals.

Keywords

💡rectificar

The verb 'rectificar' means to repair or rebuild an engine. This is a key process discussed in the video, as there is debate around whether the Ford Ranger 3.2L 5-cylinder TDCI diesel engines can be properly rebuilt or 'rectified'. The narrator argues they can be successfully rebuilt with the right tools, equipment and expertise.

💡turbodiésel

Turbodiésel refers to a diesel engine with a turbocharger. The Ford Ranger uses a TDCI (turbocharged direct injection) diesel engine. The turbocharger allows the engine to produce more power by forcing more air into the combustion chambers.

💡inyección

Inyección means fuel injection. The video discusses issues with the fuel injection system as a common cause of engine failure in these Rangers. Good fuel injection is critical for proper combustion and preventing piston damage.

💡pistón

Pistón means piston. The narrator explains that many Rangers come in for repairs due to a damaged or broken piston, often caused by problems with the fuel injection system.

💡cilindros

Cilindros are the engine cylinders. This engine has 5 cylinders in a straight configuration, which is unconventional. The video analyzes the pros and cons of this 5-cylinder design.

💡fundición

Fundición refers to the cast iron block and heads of the engine. The video examines the strength and durability of these cast iron components.

💡biela

Biela means connecting rod. The video analyzes and compares the connecting rods, an important internal engine component that connects the piston to the crankshaft.

💡caballos de fuerza

Caballos de fuerza or 'horsepower' is used to measure engine power output. The 5-cylinder 3.2L Ranger engine produces 200 horsepower, 50 more than the 4-cylinder 2.2L version.

💡laburo

Laburo is Argentine slang meaning work. The narrator explains these Ranger trucks are often used for heavy duty work, which can increase wear and tear on the engine.

💡limitador de velocidad

Limitador de velocidad means speed limiter. The narrator recommends these engines have a speed limiter installed to prevent over-revving and reduce stress on the engine.
