Toyota 3ZZ-FE engine
Content
The era of the struggle for environmental friendliness and efficiency has led to the incredible obsolescence of the legendary Toyota A-series engines. It was impossible to bring these units to the required environmental criteria, provide the necessary reduction in emissions, and bring them to modern tolerances. Therefore, in 2000, the 3ZZ-FE unit was released, which was originally planned for the Toyota Corolla. Also, the motor began to be installed on one of the Avensis modifications.
Despite the positive in advertising, the engine was not the most successful in its segment. The Japanese applied the maximum of technological and relevant solutions, did everything according to the methodology of environmental cleanliness, but sacrificed the resource, the quality of work, as well as the practicality of the service. Starting with the ZZ series, Toyota no longer had millionaires. And 2000-2007 Corollas often need a swap.
Specifications of the 3ZZ-FE motor
If you compare the A line with the ZZ series, you can find hundreds of interesting solutions. This is a whole set of equipment to improve environmental standards, as well as to increase the economy of the trip. Also pleased with the changes in the part of the crankshaft, which has become more unloaded. In comparison with the more voluminous 1ZZ, the piston stroke has decreased, which is why the manufacturer has achieved a reduction in volume and lightening of the entire block.
The main characteristics of the motor are as follows:
| 3ZZ-FE | |
|---|---|
| Volume cm3 | 1598 |
| Power, hp | 108-110 |
| Consumption, l / 100 km | 6.9-9.7 |
| Cylinder Ø, mm | 79 |
| COFFEE | 10.05.2011 |
| HP, mm | 81.5-82 |
| Models | Avensis; Corolla; Corolla Verso |
| Resource, outside. km | 200+ |
The injection system on the 3ZZ is a traditional injector without any design complications. Timing is driven by a chain. The main problems of this internal combustion engine begin with the properties of the timing chain.
The engine number is located on a special ledge, you can read it from the side of the left wheel. With the unit removed, the number will not be problematic to find, but on many units it has already been pretty worn out.
Advantages and positive factors of 3ZZ-FE
About the advantages of this unit, the conversation will be short. In this generation, Japanese designers took care of the client's wallet except when determining the volume of oil at 3.7 liters - you will have 300 grams from the canister to top up. Light weight can also be attributed to the advantages of the unit.
The following benefits should be considered:
- profitability in any travel conditions, as well as minimal emissions of harmful substances into the atmosphere;
- good injectors, reliable ignition coil, frequent ignition adjustment and system cleaning are not needed;
- pistons are reliable and light, this is one of the few elements of the piston system that lives here for a long time;
- good attachment - Japanese generators and starters live for a long time and do not cause problems;
- work up to 100 km without breakdowns, if the oil and the set of filters for the unit are changed on time;
- the manual box lasts as long as the engine, there are no special problems with it.
Also, a number of parts in the cylinder head and fuel equipment have a simple design. For example, this is one of the few units in which you can wash the injector with your own hands. True, washing at the service will be more effective. Does not cause any problems and the engine cooling system. But in case of any breakdown, it is worth immediately fixing the problems - overheating is fraught with very serious problems.
Problems and unpleasant moments in the operation of 3ZZ-FE
Like the 1ZZ, this engine has a whole range of problems and disadvantages. You can find photo reports on the repair, which show the amount of work when replacing wheels or rebuilding the cylinder head. An overhaul cannot be done here at all, so the resource of the unit is limited to 200 km, then you will have to change the engine to a contract one, and owners rarely buy ZZ again.
The main problems that the owners talk about are the following:
- A very small resource and the inability to repair the unit. This is a disposable motor, which you do not expect from Toyota.
- The timing chain is rattling. Even before the warranty run, many began to ring under the hood, which is not eliminated even by replacing the chain tensioner.
- Vibration at idle. This is the hallmark of the entire series of motors, so replacing the engine mounts does not solve this problem.
- Failure when starting off. The power system, the intake manifold, as well as bugs in the stock ECU firmware are often involved in this.
- Unstable idling, speed drops for no reason. The abundance of environmental technology is a real problem for diagnosis, sometimes it is very difficult to repair a car.
- Motor troit. This especially occurs if the replacement of fuel filters is not done on time, bad fuel is poured.
- Valve stem seals. You have to change them often, and along the way, also eliminate a number of other problems in the cylinder head.
If you do not change the spark plugs in time, you will get a number of engine shortcomings in operation. For example, you will have to perform such a rare procedure as replacing the seals of the candle wells. Particular attention should be paid to the temperature sensor. If it breaks, you will miss the moment of overheating, the motor will end.
The valves need to be adjusted manually, there are no compensators. Valve clearances are normal - 0.15-0.25 for intake, 0.25-0.35 for exhaust. It is worth buying a repair book, any mistake will cause a number of problems. By the way, after adjusting and repairing the cylinder head, the valves are lapped, you have to drive carefully.
Maintenance and regular service - what to do?
It is better to change the oil every 7500 km, although the manual says 10 km. Many owners in the reviews talk about reducing the replacement interval to 000 km. It is in this mode that it is more convenient to change the oil filter, fuel filters. Every 5, the alternator belts are inspected. It is better to replace the chain at 000 km along with the tensioner. True, the price of such a procedure is very high.
Along with replacing the chain, a pump replacement is often necessary. At the same mileage, they change the thermostat, be sure to clean the throttle valve, if this has not been done before. If the mileage approaches 200 km, repairs and expensive maintenance do not make sense. It is better to look after a contract motor or look for a replacement for a swap in the form of a different type of engine.
Tuning and turbocharging 3ZZ-FE - does it make sense?
If you just bought a car with this unit, you may notice that the stock power is only enough for the city, and even then without any special advantages. So the idea of tuning may be born. This should not be done for many reasons:
- any increase in the potential of the engine in the form of power and torque will reduce the already small resource;
- turbine sets will disable the engine for 10-20 thousand kilometers, and a lot of parts will have to be changed;
- the very process of modifying the fuel and exhaust system will drag on a very large amount of money;
- the maximum percentage of potential increase is 20%, you will not even feel this increase;
- Charger kits are expensive, and their installation will require going to an expensive station.
You will also have to reflash the ECU, work with the head of the block, install a straight-through exhaust. And all this for the sake of an additional 15-20 horsepower, which will kill the motor very quickly. Such tuning does not make any sense.
Conclusions - is it worth buying 3ZZ-FE?
As contract units, it makes sense to look at this engine if you want to sell a car, and the old engine is out of order. Otherwise, you should look at another engine, which was also installed on the body of your car. You can check this with the help of Toyota services or ask a question to an experienced master at the service station.
The engine can hardly be called good. Its only advantage will be economy, which is also comparative. If you turn the engine and try to squeeze the whole soul out of it, the consumption will increase to 13-14 liters per hundred in the city. Moreover, maintenance and repair of the motor will be quite expensive.
