Replacing the Accent Tagaz air conditioner belt with your own hands

According to the technical documentation, the alternator belt must be changed every 45-60 thousand km. You should also not forget about the quality of vehicle maintenance, since this directly affects the service life of the parts, in this case the belt. If you notice significant cracks or damage on it, do not hesitate, it is better to replace it.

Determining the causes of the malfunction

The whistling sound of the engine when starting is familiar to many car enthusiasts. So, most Hyundai Accent owners can remember this sound when starting the engine in winter and not only. This meant the water pump belt needed to be tightened or replaced. With the development of the automotive industry, everything has changed. The number of such belts in vehicles has increased.

It is worth determining why a whistle is heard when starting the engine. The main reason is the failure or stretching of one of the engine drive belts. To determine the malfunction, you need to test each belt for tension. Maybe one of these drive elements needs to be replaced because it has exhausted its service life or turned out to be defective in manufacturing, which is not uncommon these days.

Elimination methods

A squealing belt is perhaps the only reason why a whistle may occur when starting the engine. This means that the drive element has stretched and is slipping along the pulley. So, this significantly increases the wear of the belt itself, which will inevitably lead to tragedy in the power unit, unless, of course, the situation is corrected in time. Let's consider repair and diagnostic operations to eliminate whistling in the engine.

Timing drive

A whistling sound in the engine caused by a faulty timing belt is more than an urgent repair. If the part is not replaced in time, this will lead to a break in the drive, and at the same time to bent valves, which inevitably leads to costs.

The average, even the best belt should be changed no later than 50-70,000 km. Typically, car manufacturers indicate the maintenance interval for the timing belt unit in technical documentation and service books. In any case, the motorist must monitor the condition of the components and parts of the engine of his vehicle.

Step-by-step instruction

1. Loosen the four bolts securing the pump pulley. Socket wrench 10.

To prevent the pump pulley from turning, engage fifth gear.

1. Loosen the power steering pump. The top bolt can be unscrewed in two ways:

1. We loosen the tension roller locking bolt and lift it up as far as possible and tighten it in this position.

1. Remove the timing belt and tension roller.

Procedure for replacing Hyundai Accent engine belts

• The jack is installed under the right front wheel.
• Next, the engine crankcase protection is removed.
• Unscrew the bolts securing the water pump pulley (4 pcs.).
• Loosen the generator tension with the head by 12.

• Remove the alternator belt and install a new one in its place.
• Loosen and unscrew the bolts securing the power steering pump (the head must be inserted into the hole in the pump pulley to remove it).

• Replace the power steering belt.
• To replace the compressor belt, you must remove the wheel and wheel arch liner.
• Using the tension roller, release the tension, remove and replace the belt.

On a Hyundai Accent, the procedure for replacing engine belts can be determined from the manual. The job of replacing all belts usually takes 6 to 8 hours. There are no strict timing for replacing belts; usually such work is carried out after 60 thousand kilometers or when extraneous noise, whistling, or “rustling” appears in the systems. Also, a visual inspection will help determine the condition of the belts - there should be no cracks, stretch marks, or delaminations on the parts. If such defects are detected, the belt should be replaced.

When is it necessary to replace?

Engine belts are quite durable and rarely need to be replaced. There are no clearly defined deadlines establishing the procedure for replacing belts on a Hyundai Accent - they change in the event of excessive stretching of the belt, cracks appearing on it, delamination and loosening of the surface. It is believed that it is necessary to systematically diagnose the condition of belts after a mileage of 60 thousand km. Since replacing belts is quite simple, you can purchase replacement kits in advance and always carry them with you.

Poly V-belts for the Hyundai Accent engine have a long service life and are rarely changed. More often than not, the power steering belt is the first to fail. If the power steering belt is faulty, an unpleasant chattering noise may appear under the hood. In such a situation, adjustment often helps, but if the belt is too stretched, it should be replaced. When replacing the power steering belt, you will also have to remove the alternator belt (which, in case of severe wear, can also be replaced).

Location of belts on Hyundai Accent

1 – crankshaft pulley, 2 – tension roller, 3 – air conditioning compressor pulley, 4 – air conditioning compressor drive belt, 5 – alternator belt, 6 – power steering belt, 7 – power steering pump pulley, 8 – coolant pump pulley, 9 – generator pulley.

Compressor belt

All engine belts are located under the hood. The air conditioning compressor belt runs from the crankshaft pulley to the compressor pulley. Its tension occurs due to the action of the tension roller (indicated in the photo).

Generator belt

The alternator serpentine belt grips the alternator pulley, crankshaft and water pump. This part is tensioned using a special tension mechanism that moves the generator.

Power steering belt

This V-belt grips the pump pulley and the power steering pump shaft; its tension occurs due to the movement of the power steering pump housing, which is mounted on a bracket and attached to the power unit.

Installing a new timing belt

1. Before installing a new belt, be sure to check that the marks on the crankshaft and camshaft match. Install a new tension roller. We install a new timing belt in the following sequence. First, we put the camshaft pulley and tension roller on the crankshaft pulley.

We make sure that the descending branch of the belt, between the crankshaft and camshaft pulley, is tensioned.

1. We release the tension roller locking bolt, thereby the tension spring will tension the belt, and tighten the bolt.
2. We check all the marks again, and if they do not match, we repeat the procedure again.
3. We turn the crankshaft two turns clockwise and make sure that the valves do not meet the pistons.
4. We install all parts in the reverse order of removal. Everything is very simple.

Replacing drive belts on a Hyundai Accent

Replacing belts on a Hyundai Accent usually causes difficulties due to difficulty of access.
After all, there is not much space for replacing belts under the hood of the Hyundai Accent, and there are three drive belts. Air conditioning compressor poly-V belt (original number 97713-1E000), generator poly-V belt (25212-26021) and power steering V-belt (57231-29100). To understand how it all works, below we offer a diagram of the Accent drive belts. The air conditioning compressor belt runs from the crankshaft pulley to the air conditioning compressor pulley. The belt tension is provided by a special tension roller. The alternator belt rotates through the crankshaft, alternator and water pump pulleys. The tension of this belt is carried out by a tensioning mechanism that moves the generator. The power steering belt is thrown over the pump pulley and the power steering pump pulley; this belt is tensioned by moving the power steering pump housing on a special bracket that is attached to the engine. We look at the diagram of Hyundai Accent drive belts in the photo.

To replace or adjust the tension of the air conditioning belt in a Hyundai Accent, you need to remove the wheel and fender liner. Because there is no other access to this area. The tension roller, which regulates the tension, will allow you to loosen or tighten this belt. For clarity, we offer a photo. The arrow indicates the tension roller.

To remove the Accent generator belt, you need to loosen the generator tension mechanism. To do this you will need a 12mm head. The same mechanism is used to tension the belt.

But if poly-V belts for driving auxiliary units are quite durable, then the power steering belt is the first to fail. For the most part, it is he who chirps under your hood. Although the unpleasant sound can be eliminated by adjustment (by moving the power steering along the bracket from the engine), sometimes the belt is so stretched that there is simply nowhere to adjust it. Then only replacement will help. But to replace the belt we have to remove the alternator belt, without this there is no way.

Let's say the alternator belt has already been removed. Now we need to loosen the bolt securing the power steering pump to the bracket and unscrew another one on the other side. In the next photo, the locations of the required bolts are marked with arrows.

If you can get to one bolt with almost any wrench, then the second can be unscrewed only with the head, pushing it through the hole in the power steering pump pulley.

In principle, no special devices or special tools are required when replacing Hyundai Accent belts. about replacing the Hyundai Accent timing belt here. You can read it, it will definitely come in handy.
