Hyundai Accent coolant. Which coolant is better to choose?

Stages of replacing the coolant Hyundai Accent

Since there is no drain plug on the engine, it is best to replace it with a complete flush of the cooling system. This will allow you to completely flush out the old antifreeze from the system and replace it with new one.

The best option for replacement would be to have a hole or overpass for more convenient access to the drain holes. Instructions for replacing the coolant will be useful for owners of the following Hyundai models:

• Hyundai Accent Restyling;
• Hyundai Accent Tagaz;
• Hyundai Verna;
• Hyundai Excel;
• Hyundai Pony.

Popular engines are petrol with a volume of 1.5 and 1.3 liters, as well as a diesel version with a 1.5 liter engine. There are also models with other displacements, but more often they were sold in other markets.

Coolant drain

All work should be carried out when the engine has cooled to 50°C or lower, so there is time for preparatory work. It is necessary to remove the engine protection, as well as the protective plastic, which is secured with 5 10mm head bolts, as well as 2 plastic pistons.

Next we move on to the main procedure:

We find a plastic drain plug at the bottom of the radiator and unscrew it, having previously placed a container under this place into which the old antifreeze will drain (Fig. 1).

• We remove the expansion tank for flushing and draining, since sediment often forms at its bottom. Which can sometimes only be removed mechanically, for example using a brush.
• Since there is no drain plug on the block head, we will drain it from the hose that goes from the thermostat to the pump. Removing the clamp with pliers is not convenient at all. Therefore, we select the correct key, unclench the clamp and tighten the pipe (Fig. 3).

  In this way, we managed to completely drain the antifreeze from the Hyundai Accent, so we can collect everything and put it in its place. After which you can proceed to the next stage of replacement.

  Flushing the cooling system

  Before flushing, we check that all the pipes are in place, and that the drain valve is closed, and proceed directly to the procedure itself:

  1. Fill the radiator with distilled water to the top and close the lid, also fill the expansion tank halfway.

  We start the car and wait until it warms up completely, until about the second time the fan turns on. In this case, you can periodically add gas.

• We turn off the car, wait until the engine cools down, and drain the water.
• We repeat the procedure until the water after rinsing is clear.

Usually clear water comes out after 2-5 runs. Each case is individual and depends on many factors.

After a well-carried out flush, the antifreeze on our Accent will fully perform its function until the next service replacement. If this procedure is not followed, the service life may be sharply reduced, since plaque and decomposed additives of the old coolant remain in the system.

Filling without air pockets

If the replacement is carried out with a complete flushing of the system, it is recommended to use a concentrate as a new fluid. Since distilled water remains in the system, in a volume of 1-1.5 liters. The concentrate must be diluted taking into account this volume.

Now we begin to pour new antifreeze into the radiator to the level of the bypass tube, as well as to the middle of the expansion tank. After this, close the covers and start the engine. We wait until it warms up completely, sometimes increasing the speed.

That's it, now we wait for the engine to cool down, check the fluid level in the radiator and tank. If necessary, make gravy. Fill the tank to the letter F.

With this approach, no air lock should form in the system. But if it does appear and the engine overheats because of this, you need to perform the following steps. We put the car on a hill so that the front is raised up.

We start the engine, warm it up with a constant increase in speed to 2.5-3 thousand. When doing this, we look at the temperature readings; we must not allow the engine to overheat. Then we turn off the engine and open the radiator cap a little so that it does not come out of gear, but the air can escape.

Usually after this you can get rid of the air lock. But sometimes this procedure must be repeated 2-3 times.

Anyway, I took Coolstream Optima 5kg red)) Thank you all!

Gulfstream ley! I like it and it’s great for the money!

Well, yes, I don’t argue, there’s also synthetic, I put it in Ford, it’s down to -45))

When they changed it for me, they drained the radiator, drained the pump, replaced the thermostat, replaced the hose and reassembled it. Then about 3.8 liters of antifreeze came in (this takes into account what was poured into the expansion tank).

You can’t drain it all yourself in the garage, only partially replace it, wash everything with distilled water until it runs clean, and pour in pure concentrate, you should get about 1 to 1

I fill it with blue-green mobile. Already 6 years. Great flight
