An understandable desire of any vehicle owner is a reliable motor capable of serving for a long time. Of course, no one wants to spend money and time on car service workshops once again. Experts and motorists speak ambiguously about the 2LTE engine: for some it raises doubts about “longevity”, for others nothing but harsh criticism. At the time of development, he was the most promising motor. But operation and time put everything in its place. Let's take a closer look at its parameters.
About the manufacturer
Diesel powertrains have been talked about for a long time, and the 2LTE engine has taken a special niche in the line of Toyota models. The collection of engines marked L was thrown by the Japanese into the "paws" of the world car market back in 1977. The production of some representatives of this class has not yet been discontinued. And the line has grown so much that to collect all the models in one structured table has becomealmost impossible.
The manufacturer presented us with several modifications. According to some reviews about the 2LTE engine, this engine is the worst in the entire model range of the company. Why such an attitude? Overheating resulting in expensive repairs is considered a total problem. To this is added a flaw in the cooling system, turbine breakdowns. There are motorists who hold the opposite opinion. Let's turn to the benefits first, considering the independent judgment of car specialists.
Expert opinion on benefits
According to the experts who tested the 2LTE engine, the diesel in-line four is quite suitable for lovers of a balanced ride without extreme sports. Simplicity of design, high-pressure fuel pumps do not cause much trouble to the driver, subject to competent operation, frequent diagnostic procedures, and timely replacement of worn parts. Although not without individual flaws. Diesel is much more economical, so in Europe most drivers switched to such engines, and the tax has to be paid half as much for it as for gasoline. The maximum speed of the car - 120 km / h - is not suitable for lovers of recklessness. If you do not want to stand out from the crowd and want to stick to a balanced driving technique, this unit is perfect.
On the technical side of the issue
Diesel fuel is cheaper than gasoline. And this is an advantage formotorists. On the Toyota Chaser, Toyota Cresta, a 2.4-liter 2LTE engine is installed, which has power parameters of 97 “horses”. Engineers supplemented it with turbocharging. In this version, the designers added electronics and an automation complex to the high-pressure fuel pump. They equipped it with the EFI injection system, which was a resounding success at the time of its first releases due to the even distribution of the air-fuel mixture. Representatives of the Land Cruiser Prado brand began to use this power unit. Often, owners of vehicles with such a unit complain about the insufficient performance of the 2LTE engine in terms of power.
By installing additional automatic transmission cooling and an intercooler on the Chaser 90, you can accelerate to hundreds by 70 km/h in 10 seconds. In urban conditions, most car owners take about 15 liters.
Electronics break down on diesel "Japanese" of this category. Breakdowns occur due to the low quality of fuel, the wrong approach of the owner of the car. Since overheating is a weak point for this representative of the motor line, the main thing is to prevent this during operation. When buying a used car, it does not hurt to look in the fuel tank for "gurgling". This is clear evidence of cracks in the head.
Jeep drivers have a particularly hard time: the engine does not pull as it should be, due to the weight of the SUV.
How to recognize faults?
The following points can be highlighted.
- The car owner notices an increased "appetite" for fuel.
- Decreasing dynamic performance compared to the day of purchase in the showroom.
- Knocks, vibrations appear.
- The device does not have good traction, which means that the matter is in the injection pump dosing solenoid.
Common problems
Motorists have to deal with the problem of 2lte engine sluggish revving. This is found out in the service during diagnostics or is felt by an experienced driver while driving. Smoke starts at idle, not to mention the situation when pressing on the gas pedal. The picture is often observed after a major overhaul, although at the same time the injection pump and nozzles operate in normal mode. The reason turns out to be banal: the camshaft creates a problem.
According to the manual, the "aspirated" camshaft has cams located about 1 mm above the turbodiesel cams, in practice it turns out that the valve opening area is different. Replacing the camshaft solves the issue in a positive way. The conclusion suggests itself: when mounting the head on 2LTE, for example, it is not worth installing a 3L with reinforcement assembly with a camshaft, and for motors 3l, 5L it is also better to use a camshaft from 2LTE.
Toyota Hilux Surf won't start - what to do?
Often the owners meet with the refusal of the "swallow" to start. Is there really a difficult repair of the 2lte engine that will affect the wallet? Nobody wants this kind of outcome. The most common cause of this behavior is air in the fuel system.
Driver desperatelystrives to do the work of correcting the situation on his own, reviewing logbooks with a photo of the 2LTE engine, reading auto forums on the Internet. For beginners, for the first time, it is still recommended to carry out repair work in a service center, because it is not a fact that even the most competent advice from "experienced" can be effective for a particular situation. Some people are helped by pumping the injection pump using the following algorithm of actions.
Unscrew the glow plugs.
Try to bleed the starter.
What are we seeing? After several attempts to pump, air mixed with diesel fuel comes out of the hole under the glow plugs, forming a light smoke. On screwed candles, the motor does not have enough power to push through the nozzle; without them, air freely blows through the nozzle. As a result, solarium enters the combustion chamber, the fuel lines get rid of air locks.
This method shows the working condition of the injectors and that there were no problems with them when the engine failed to start. Next, the glow plugs are screwed back. The engine is running and ready to go!
What else happens to the turbodiesel?
Strange error code 32…
The engine stalls, the on-board computer issues an error code 32 of the 2LTE engine. What to do in this case? The reason is that the wires on the injection pump fuel dispenser valve were shorted. The open circuit must be repaired. A tachometer, as a prerequisite for transport companies engaged in cargo and passenger transportation, can produce 50 rpm. The actual position reaches up to 400revolutions. The injectors run out of fuel. In this position, the mechanics are of the opinion that the solenoid valve needs to be changed.
Helpful tips for adjusting fuel delivery
A normally running diesel should not be accompanied by black or blue exhausts. The black color of the smoke, unambiguously, indicates increased fuel consumption, the gray one indicates increased oil consumption. The adjusting screw of the Spill Vilve bypass valve plunger installed on the Toyota Land Cruiser Prado Turbo Kit must not be fully tightened! It wears out more often compared to the pump plunger pair, so the following procedure is required as part of a scheduled repair.
The protective cap is removed with pliers and the lock nut is unscrewed.
The motor warms up to the correct operating temperature.
It is necessary to spin up to the degree of a feeling of lack of fuel. Next, a leisurely twist is carried out, checking by pressing the accelerator pedal. The tachometer will show how many revolutions the “horse” has given out.
Adjustment is not carried out when the engine is turned off, otherwise damage may be caused. Feeling an increase in speed during adjustment, unscrew the screw in the opposite direction. The result is a reduction in the cost of buying fuel.
With moderate driving, problems may not arise up to 70 thousand km.
