Engines Peugeot TU3, TU3A, TU3JP, TU3M
Content
Peugeot engine with a volume of 1.4. liters - TU3K or K1G is the ancestor of the extensive TU line. It originates from 1986. The power unit under consideration in a number of sources carries the TU3A index, which leads to many questions.
History of creation
Peugeot 206 cars are equipped with engines that run on gasoline with a fuel volume of 1,1; 1,4; 1,6 liters or engines using diesel fuel, with a volume of 1,9 and 2,0 liters.
The existing power units of the TU series can be described as: 4-stroke, with several cylinders arranged vertically, the camshaft is located at the top. The engines are equipped with a carburetor, a system of central or distributive injection of a combustible mixture.
Power units, depending on the volume, are made of light aluminum alloy or low-alloy cast iron. At the moment, there are various ways to install cylinder liners. They also depend on the size of the engine and can be inserted into special holes, or located directly in the block.
TU (TU3) is an 8-valve, 1,4-liter gasoline engine with four cylinders. The engine of this brand first appeared in 1986 on a small model of the Citroen AX car, and then it will be installed in the Peugeot 205. After seventeen years, this unit is becoming more widespread and can be found on the second generation Citroen C3 and Peugeot 207. But this is already not the same motor that was in 1978, it has undergone significant changes and improvements.
Improvement and refinement of the TU3 engine led to the emergence of a new engine with 16 valves and a volume of 1.4 liters with the ET3 index. The number of horsepower increased from 75 to 88. This variation of the motor was used only for 8 years. The production of this internal combustion engine had to be abandoned, as it did not meet all the requirements of Euro 5.
TU3M - refers to gasoline engines with a volume of 1.4 liters and power dynamics of 75 hp.
The Peugeot ICE under consideration - TU3A or KFV was in production from 2005 to 2012 in France and, in its design, represented the modernization of the previously developed TU3JP electric motor to the existing EURO 4 environmental standards. This previously developed motor equipped such small vehicles as Peugeot 206, 207 and " heel" Partner.

Each of the engines, despite the similarities, differs in certain characteristics, albeit to a small extent.

To find out the engine number, you need to find a special plate, which is located on the cylinder block. If the cylinder block is made of a hard material, then the number can be embossed directly on it.
The number, which is located on the engine, includes three components: a reference number, which will help you find the right spare part, the code for this engine, and the last part, the serial number of the unit itself.
Thus, each of the varieties of the engine is characterized by its own special features. However, what they have in common is volume. It is the same for the entire presented line. Otherwise, the engines have some differences. This also applies to fuel consumption. Although it must be admitted that all engines are characterized by economy in this regard.
Reliability and issues
TU engines are structurally simple and therefore they can be repaired at any specialized service station. Most often, problems arise with sensors and failures occur in the ignition system. Troubles can occur due to dirt on the throttle, IAC. There may be problems with air leakage in the intake manifold.
It is important to always monitor the condition of the timing belt, as if it breaks, the valves can bend. It is best to check the belt every 50 thousand kilometers. Such a frequent check is due to the lack of a hydraulic compensator.
The Peugeot TU3JP motor exists in two varieties KFW or KFX. They both belong to the TU3 series. A similar unit was produced for several years, until 2006. In this model, it is necessary to replace the timing belt every 100 thousand kilometers.
One of the most common French engine failures is head gasket damage. This causes oil to enter the cooling system or leak out. Sometimes the upper lambda probe fails, and when traveling long distances, the exhaust pipe may crack.
Each brand of engine requires an individual approach. A typical breakdown event can be associated with:
- Use of poor quality fuel.
- Late technical inspection.
- Insufficient attention on the part of the driver to the problems that have arisen.
- Driving style. If a driver is behind the wheel of a car, who picks up speed sharply or also brakes sharply, then sooner or later this will lead to various engine breakdowns.
If we consider the problem of malfunction of the above power units from an economic point of view, then it is better to overhaul the engine. The acquisition of a contract motor can be associated with certain difficulties. Most often, the supplier does not know the history of such an engine. Therefore, replacing the motor with a new one is beneficial only if the car is often used for commercial purposes. For everything else, overhauling the engine will be the most rational solution.
What cars were these engines installed on?

| TU3A | CITROEN | C2 C3 |
| tu3m | PEUGEOT | 106 205 405 |

According to the reviews of many car owners whose cars are equipped with TU line engines, only a positive conclusion can be drawn about these power units. Good handling of the vehicle, dynamics, safety, attractive appearance are noted. If we talk about an expensive model, then the interior design deserves an extremely positive assessment.
An unpleasant surprise for car owners is the cost of maintenance, which is often overstated. It takes a lot of time and effort to find a truly commensurate price and quality. In addition, according to car owners, cars with these engines do not have high cross-country ability, so the car is more suitable for an urban environment.
