How to flush a radiator — examination ZR

Tell when you need to wash the radiator of engine cooling system

The engine radiator is polluted, not only outside in his tank often accumulate oxidation products.The engine radiator is polluted, not only outside in his tank often accumulate oxidation products.

Grille — a kind of greasepaint: everything that passes through it, is deposited on the radiator. And radiators in the car can be several from the charge-air cooler (intercooler), power steering, automatic transmission, a / C condenser. The radiator of the cooling system of the engine always installs the latest in the direction of flow of air, means he’s the worst blown by incoming air flow. And often it is because of him planning water treatment. After all other heat exchangers in the contamination only partially lose their effectiveness, and the engine cooling system is more like a toggle switch with two positions: “normal work” and “guard boil!”.

The engine radiator is polluted, not only outside in his tank often accumulate particles of rust and scale, and oxidation products of aluminum parts. And if you thought about flushing radiator on the outside, it makes sense to combine it with a coolant change. The terms of the replacement fluid in all cars are different, but believe me from experience, if you run 80-90 thousand miles to update it does not hurt.

Consider ways to clean radiators. We will act, as bequeathed by the fathers of dialectics, from the simple to the complex.

The dirt between the radiator engine coolant and a condenser of the air conditioner, without disassembly can not win.The dirt between the radiator engine coolant and a condenser of the air conditioner, without disassembly can not win.

Easy

Easiest cheap cars without air conditioning — they have a single radiator. Wash it independently, even without removing from the machine. For example, from a hose in the country. Or reaching the sink. The water pressure should be powerful, to bent a thin heat sink plate. If this happens, the radiator will not pass through the air and, accordingly, will not be able to effectively cool the liquid.

Before the water treatments it is advisable to install behind the radiator screen of plastic film: it will block the path of the water and the mud flying on the drive belt, the generator, and candles. It is important not to fill and the fan motor. He is not afraid of splashes, but should not direct the jet directly into it under pressure.

Wetted heat exchanger of the conditioning cleanser. Suitable diluted composition to clean wheels. Brush of medium hardness along gently hold the thin plates of the condenser is to prevent them from bending.Wetted heat exchanger of the conditioning cleanser.

After processing, the chemistry, the heat exchanger of the air conditioner must be thoroughly rinsed with water. Heat-conductive plate of the capacitor Largus during the operation suffered seriously from the flying stones in the lower part bent almost everything. But the air conditioner is working properly, why change it to a heat exchanger, we considered it inappropriate. Some of the worst air to flow through the air conditioning condenser to radiator system to compensate for the more frequent inclusions of blower motor.After processing, the chemistry, the heat exchanger of the air conditioner must be thoroughly rinsed with water.

And here is the main “culprit celebrations” — the radiator of the cooling system of the engine. Visible fat deposits is dust and poplar fluff, liberally soaked in something oily.And here is the main “culprit celebrations” — the radiator of the cooling system of the engine.

The company

If the radiator for cooling the engine is mounted in a package with other radiators, it is flushing without dismantling unlikely to give the desired result. The fact that after washing the first heat exchanger will inevitably lose power and effective cleaning of the second radiator will not work. In this case, you can try to flush the radiator with the condenser exposed, and the radiator of the cooling system from the inside. But I know from experience that between the two heat exchangers sometimes leaves something like a felted blanket of poplar fluff and other “materials”. Sometimes you can get rid of a little blood, dismantling the grille (for those vehicles where it is removed separately from the bumper). This will give the opportunity to wash the heat exchangers without dismantling. And then, by tilting the radiator engine coolant and disconnect the top mounts to clear the space between the radiators.

Moistened on both sides of the radiator we soap up beyond the car shampoo and wash thoroughly. If there is no running water, can be rinsed in a suitable container. In this case, the process will take a little more time and the result will be worse.Moistened on both sides of the radiator we soap up beyond the car shampoo and wash thoroughly.

Continue to rinse until flowing water is clear. In the same way should be washed and the entire cooling system. To supply water to the surge tank you need until then, until all the dirt.Continue to rinse until flowing water is clear. In the same way should be washed and the entire cooling system.

Removed the radiator thoroughly wash the inside of the Bay a few times and drain the water. There is no need to apply additional funds from the scale, if you used a good coolant.Removed the radiator thoroughly wash the inside of the Bay a few times and drain the water.

On cars with solid mileage at the same time you need to replace the coolant.On cars with solid mileage at the same time you need to replace the coolant.

The most difficult but also the most effective way to clean the radiator of the engine is completely disassembled. This will disconnect and remove the blower motor Assembly from casing and disconnect the heat exchangers of the engine and air conditioning. With the a / C condenser is more complicated: after dismantling will have to re-charge the system with refrigerant. Therefore, a capacitor is simply trying to take away and rinse out without depressurization of the air conditioning system. In this shot the engine cooler, I recommend to clean not only outside but also inside. For absolute success you need to drain the coolant from the system and rinse with clean water to all cooling circuits. This will increase the efficiency of the heater, as the heat exchanger accumulates dirt.

Rays of light penetrating through the entire surface of the radiator, is evidence that the work is done efficiently.Rays of light penetrating through the entire surface of the radiator, is evidence that the work is done efficiently.

For different machines the method of extraction of the radiator of the cooling system is different. In most cases, it is necessary to remove the front bumper and grille, as well as dismantle bottom protection of the engine or plastic mud flaps. Some of the cars under, you’ll bumper beam amplifier, which is welded to the front ends of the side members, which complicates the access to the radiators. In others it can be removed by unscrewing a few bolts, allowing access to heat exchangers.

If you do not decide to flush the radiator on their own, you can entrust this work to professionals. The official will act in full — with the removal of the radiator, but the amount of requests is considerable. For example, the owner of a mid-sized crossover in Moscow will have to pay about 12 thousand rubles.

Informal services, specializing in cars of the same brand, usually evaluate their services is somewhat lower. More accessible offers garage masters, but the quality is often appropriate. Wash at the car wash removed the radiator will cost 100-300 rubles.
