Honda D17A engine
Content
The D17A rolled off the assembly line for the first time in 2000. Initially intended for heavy vehicles, it was distinguished by the largest dimensions of the entire D series. In the late 90s, there was a need to create a new engine in order to provide Japanese heavyweights with the necessary power. The way out was the creation of a volumetric motor D17A. It is important to note that despite the large size, it was even slightly lighter than its predecessors.
Where is the serial number located?
Searching for the engine number on all Honda models will not be difficult - as motorists say, here it is located "humanly" - the plate is located on the body from the front, just below the valve cover.

The table shows the main characteristics of the power unit and their features. Initially, the base model was released, which was mentioned above. Studying the needs of consumers, after some time several series left the assembly line, which had minor design differences, as well as different power and efficiency parameters. To begin with, let's analyze the D17A design, which was taken as a basis, we'll talk about the changed configurations a little later.
External Description
The base engine is an injection 16-valve internal combustion engine, with an in-line arrangement of cylinders. The new engine model differs from its predecessors in a more durable composition of the aluminum alloy that makes up the cylinder block. The case height is 212 mm. In the upper part is the cylinder head, in which the combustion chambers and air supply channels have been modernized. In its body are machined beds for the camshaft and valve guides. The intake manifold is made of plastic, and the exhaust system has a brand new catalyst.
crank mechanism
The engine has a crankshaft on five bearings, connected to connecting rods with a height of 137 mm. After the modifications, the piston stroke was 94,4 mm, which made it possible to increase the volume of the combustion chamber to 1668 cm³. Plain bearings are located in the support and connecting rod journals, providing friction reduction and the necessary clearance. Inside the shaft there is a channel necessary for supplying oil to the rubbing elements.
Timing
The gas distribution mechanism is represented by a single camshaft, belt drive, valves, their guides, springs and pulleys. Each cylinder has 2 intake and 2 exhaust valves. There are no hydraulic lifters, adjustment is carried out using screws. The presence of the VTEC system on the engine allows you to control the degree of opening and stroke of the valves.
Cooling and lubrication system
Both motor systems are manufactured according to standard technologies, without any structural changes. As a coolant, it is recommended to use a specialized Honda type 2 antifreeze, designed specifically for this brand of engines. Its circulation is provided by a pump, the thermostat regulates the flow of fluid. Heat exchange takes place in the radiator.
The oil system is represented by a gear pump, a filter and channels in the engine housing. Unlike its predecessors, this motor is less wear-resistant during oil starvation.

Reliability, maintainability, weaknesses
Any sensible minder will tell you that the engine life largely depends on the quality of the oil and operating conditions. Therefore, the manufacturer gives a factory warranty, which is about 300 thousand kilometers. This means that during this period, even with frequent work at high speeds, the heart of your car will not require major repairs. Undoubtedly, the main rule is the timely passage of maintenance in a planned manner. As practice shows, with medium loads and the use of good oil, the engine life is significantly increased by 1,5, and sometimes even 2 times.
According to the reviews of car owners, the D17A models are unpretentious in repair. Despite the large dimensions, the main parts of both the engine body kit and its design can be easily purchased on order at any auto shop. Undoubtedly, its predecessors could be repaired even in garage conditions, but our test subject can also be sorted out with 2-3 intelligent assistants.
Main weaknesses D17A
The power unit does not have any major sores, serious problems arise either from old age or from a high mileage that exceeds the warranty.
The most common faults:
- Lack of hydraulic lifters - every 30-40 thousand kilometers it is necessary to adjust the valves in a planned manner (clearances: inlet 0,18-0,22, outlet 0,23-0,27 mm). Under heavy loads, this procedure may be required even earlier, as you will be told by the characteristic metallic sound from under the hood during the operation of the internal combustion engine.
- Difficulty starting in the cold season - capacitors freeze in severe frosts. It is necessary to warm up the control unit, after which the engine will start. Sometimes the issue is resolved by replacement.
- It is advisable to routinely change the timing belt, the resource of which is 100 thousand km. If this rule is not observed, the valve will often bend when it breaks.
- In order to avoid boiling and leakage of antifreeze, it is necessary to replace the cylinder head gasket in a timely manner. If it is damaged, coolant may enter the combustion chamber and violate the integrity of the cylinder-piston group. Also along the way, you can replace the compression and oil scraper rings, caps, etc.
- Speed floats - a classic nuisance, most likely the reason is a clogged throttle assembly. It needs to be cleaned.
What kind of oil to pour?
The choice of brand of oil is a serious issue on which the longevity of the car's heart depends. In the modern market, a huge choice can confuse a novice motorist. According to the D17A instruction, it is “omnivorous” - brands from 0W-30 to 15 W 50 are suitable for it. The manufacturer strongly recommends avoiding fakes and purchasing only branded oils from reliable suppliers. Replacement must be done every 10 thousand kilometers, optimally - after 5 thousand. With longer operation, the oil loses its properties, settles on the cylinder walls and burns out along with the fuel mixture. Due to its waste, oil starvation occurs, which can lead you to overhaul the engine.
Tuning possibilities
As with any motor, making improvements to get better performance will cost a pretty penny. It is more advisable to replace the unit, but if you want to pump this particular engine, you can choose from two options:
- Atmospheric - it is necessary to squander the drain or replace the throttle with a larger one, install a cold intake and direct exhaust, as well as a camshaft with a split gear. Such a refinement will make the motor 150 strong, but the cost of work and spare parts will rise to a substantial amount.
- Turbine installation - it is necessary to observe humanity and adjust its operation to 200 hp so that the engine does not fall apart. To increase reliability, it is desirable to replace the parts of the crank mechanism with forged ones, to reduce the compression ratio. An important component is the installation of a cold intake and direct exhaust.
It should be noted that any improvements, even those carried out by a professional, reduce the resource of the internal combustion engine. Therefore, the most optimal would be to replace the class of the motor or the brand of the car.
