With our report on the subject "Improved coolant" we have dealt extensively with the various coolants for the vehicle's cooling circuit. For example, if you don't want to rely on the classic mixture of ethylene-glycol-water, you have it improved coolants from the Tuning trade a way of using special funds different specifications to purchase by vehicle and engine. Especially for heavily tuned Engines or for cars in extreme areas are they interesting. And today we would like to meet the Features from the classic Antifreeze deal with. Therefore, below everything you need to know about the Radiator antifreeze.

Worth knowing - cooler antifreeze

Properties of the radiator antifreeze!

The cooling water leads to a Dissipation of engine heatso it doesn't become one overheating of the unit can come. In winter the cooling water must protected from freezing will. This is the only way to prevent the vehicle and, in particular, the engine Damage suffers. For this purpose, the cooling water in the cooler with a ANTIFREEZE CONCENTRATE enriched. By the Stabilize of electrical conductivity of the coolant becomes a premature boiling prevented. At the same time, the antifreeze is useful because there are mineral deposits in the cooling system counteracts and also as rustproofing acts in the cooling system. Because of these positive properties, the cooling water should always be enriched accordingly and must also be checked regularly.

This is how the antifreeze is used correctly!

The Radiator antifreeze in the Cooling water tank. This is mostly a more transparent or white Plastic container. The container is marked with a warning symbol in front of a risk of burns. Should be an individual radiator cap be installed, then of course they are optics and also the Statements different. If the engine is still warm, the pressurized container may Not open will. The Refill from cooling water and Antifreeze is therefore only with cooled container is possible.

Durability of the radiator antifreeze

The radiator antifreeze only has one conditional durability in the cooling system. Because of this, it must be done at regular intervals change. The specified intervals vary depending on the manufacturer. All becomes lump sum three years or a corresponding one every 50.000 km Change recommended. It's up to the old consistency from antifreeze that one regular change the liquid should be made. Older frost protection forms Blow, the burst can. Here they judge damage in the cooling system the metal walls and can use the cooler break through and also damage to the water pump cause.

Correct mixing ratio - radiator antifreeze!

Antifreeze comes with Water mixed. The mixing ratio is between 60:40 and 50:50. The appropriate manufacturer's instructions get noticed. If you don't want to mix yourself, you can also use mixed ones finished products To fall back on. The correct mixing ratio in the cooler can always be achieved with a Cooling water spindle to be checked. When filling in the antifreeze, it should be noted that that it is mixed with water. Will the means pure filled in the container, it can be Effect not unfold.

How to check coolant and antifreeze!

Frost protection should twice a year be checked. Regardless of this, the level of the cooler tank should be monthly being checked. All tests should always be done with the engine is cold. To check the level of the cooling water, just look at the surge tank. The level should between the minimum and maximum Mark. As soon as the level below minimum must be liquid refilled will. However, refilling is only allowed when the engine is cold respectively. If the motor has not yet cooled down, the hot liquid inside is still under pressure and can open when it is opened shoot out and Body Parts scald, To Review the antifreeze concentration can be a Test spindle be used. This is only in the cooling water held. The temperature displayed should be below minus 20 degrees lie. Otherwise the antifreeze must refilled .

Too much antifreeze in the cooling system!

Located in the cooler zu viel Antifreeze, the cooler can be optimal cooling performance is not achieve more. So there can be no more heat derived be and the engine overheated sooner or later. An overheated engine can cause you engine failure carry away.

No antifreeze - pure water?

To engine cooling water is required, so in an emergency only initially pure water be filled into the cooling system can. However, one should remember that a suitable one quickly Coolant concentrate refilled should be so that the correct frost protection of the cooling system is restored.

This is how to behave if the engine overheats!

At a overheating of the motor usually lights up Warning light in the dashboard. Then the ride should as soon as possible gestoppt be so the engine the abkühl can. It makes sense to open the hoodto make the heat faster escape and the engine cools down quickly. That too Enable of Heating with ignition switched on and switched off Motor can help. The heating on the high Heat level and on the Set the highest fan level. However, you should definitely use the vehicle battery and keep an eye on other consumers like that Radio or Light turn off. Then it should Coolant level be checked as soon as the engine cooled down is. Possibly is Radiator water to refill. After that is a Continue driving is also possibleto possibly go to the nearest workshop. However, it should be included low speed hazards (high speeds are to be avoided at all costs). Again, that can help Heating keep walking to leave.

Does coolant have to be disposed of?

Are coolants highly toxic and will like for this reason Hazardous waste disposed of. Such substances are allowed under no circumstances in the groundwater reach. This means that the coolants must not simply be in the spout be disposed of. Coolants that have to be changed must be in one resealable container be caught and to a corresponding Acceptance point to be brought. Basically it is like with Waste oil.

Which coolant should be used?

The frost protection should be on the manufacturer's instructions be coordinated. All the solutions are differently composed. Another coolant could additives contain that negative auf die cooling channels affect and this worst case clog. For this reason it is always better to start with just simple tap water or distilled water refill until the correct coolant is available for filling. Generally it is normalwhen in a closed cooling water system occasionally some liquid refilled must be because Diffusion or Evaporation are responsible for this. This is always about small quantities. A refill of 250ml up to 500ml in the year we perceive as normal. However, if a significant amount of fluid has been lost, there may be a problem Defekt before that in the Workshop needs to be fixed.

Washer fluid antifreeze

So that in winter the Windscreen washer lines do not freeze, must also im Washer fluid tank Antifreeze to be available. For this purpose, the remainder of the is consumed at best in autumn Summer cleaner, so that Antifreeze solution can be filled. The Winter windscreen cleaner with Frost protection effect is called concentrate Mix it yourself offered. But it can already ready mixes be used. But it applies urgent note that the Antifreeze for the Washer of that for that Cooling circuit differs. under no circumstances these liquids are allowed reversed will. The corresponding openings are in the engine compartment clearly marked. The cover for the washer fluid is usually with a Windshield wiper icon and / or one Windshield marked. Here too, of course, care must be taken if an individual Washer fluid cover is installed.
