Information is intended for cars Opel Astra N / Zafira b 2004, 2005, 2006, 2007, 2008, 2009.
Almost 99% of cars have engines internal combustion, during which a lot of heat stands out. If you do not fall, the engine will stop working. It is just jammed. A cooling system is the main role in which the cooling radiator is played for the discharge of excessive heat. Depends on its health normal work Engine, because without a radiator, the engine will constantly overheat.
Structurally, it is installed behind the radiator grille in front of the engine. The cooling element is made in the form of thin tubes on which the cooling edges are mounted. For better thermal conductivity, the tube is made of fine copper or aluminum.
Replacing radiator cooling Opel Astra H: Background
The reason for the malfunction may be the following:
- The surface of the cooler is clogged with garbage. As a result, pollution does not allow air to wash the tube, which disrupts the temperature regime.
- Mechanical damage to solid items in the speed. As a result, the tubes are damaged, and the fluid flows.
- Due to the use of tap water, salts are deposited on the walls of the tubes. The heat transfer drops sharply, and the engine overheats.
The fault is manifested by an increased coolant temperature, which is constantly growing during the movement and can achieve a critical mark on the dashboard indicator.
In this case, you should immediately stop, turn off the engine and check the coolant level. If the level is normal, check the fuse of the electric fan, serviceability and tension drive belt Water pump.
IMPORTANT! Do not open the cover expansion tank Immediately after turning off the engine. It is necessary to make a cool motor, otherwise you can get serious burns and face burns.
If the fault cannot be determined, you should call the tow truck and send Opel Astra n in the car service for accurate diagnostics.
Do not trust services that do not have technical base and qualified personnel, whose experience would be confirmed by certificates.
Replacing the radiator of the air conditioner Opel Astra N in Car service
We have mechanics specialize in certain types of work and perform them with high quality. First of all, our mechanics produce diagnostics and only after that begin to repair.
With strong mechanical damage, it is recommended to replace the radiator completely. It should also be done with a large deposition of scale on the walls. When polluting it is washed with a detergent vacuum cleaner, if it does not help, it is dismantled and washed with detergent in the bath, and then under pressure with clean water.
IMPORTANT! IN modern cars, such as Opel Astra H, arise difficulties with dismantling - it is necessary to remove cladding elements. And this requires certain knowledge and devices that are not available in each car service.
This work should be entrusted to experts with a large production experience and experience in carrying out similar repairs.
Why is it necessary to replace the radiator Opel Astra H in the car service?
The replacement of the cooling element should be performed in the verified service station for the following reasons:
- often novice mechanics confuse leakage of liquids from nozzles with damage to the cooling element;
- if the damage of the tubes is small, they simply stop them, and in inexperience the entire element change the new one;
- if there is a scale, it is removed using means dissolving it; It is changed only if the washing helped.
REFERENCE: If the car service mechanic immediately offers a cooler to replace, you should contact another service, which will first make a malfunction diagnose and only after that will offer the necessary repairs.
Algorithm for replacing the radiator Opel Astra n
In order to replace the Opel Astra H radiator, you must perform the following steps. Before starting work, the coolant is drained.
ATTENTION! All work must be performed with marginal caution, because The element of the cooler has very thin tubes, which with careless handling it is easy to damage.
To access the parts, it is necessary to dismantle the decorative grid closing the cooling element, for which the fastening bolts are unscrewed, and then near the headlights are fitted with a screwdriver and free the latches. This operation is done along the entire lattice, after which it is removed.
Then the piston is dismantled, and the fastenings on the bumper are declined. Next, you should unscrew the fastening bumper bolts to the hider and the wings in the arches of the wheels. After that, we unscrew the pistons of the lower fastening of the bumper to the subframe.
To dismantle the bumper, you must pull it from the wheel side. It comes out of the guides in the wings and is easily removed. After that, the air conditioner radiator is released by unscrewing the four fastening bolts and removing the fastening hardware of the top panel of the cooling element and the air intake nozzle.
Release the neck of the washing liquid tank, pulling it on itself, twisted the sixth fastening bolt of the main radiator. From the engine side, the fan is dismantled, pre-disconnecting the electrical french connections.
Disconnect the fan power sensor connector. After that, dismantle the nozzle from the pump and the other remains. The final stage is unscrewed the lower mounting brackets, their two on each side. To dismantle the cooler, it is necessary to carefully remove the air conditioner radiator and remove the main one.
Installation of a new or renovated is made in reverse order.

How many did not climb on the forum, is not a sense.
So I could not find how to change the cooling radiator ...
I decided to change myself, and make a small photo report, who can come in handy.
It all started when I learned that Opels Astra Ash with Motors 1.8 and a Box Machine, there is a problem when antifreeze comes from the automatic defect, the Antifreeze is falling into the automatic transmission and judging by the statistics, the box must or capital or change what pops up the beautiful amount . So thought that provided if the radiator would fly, it would be necessary to change and decided that it was better to change the radiator in advance. I ordered it on the existential (13 00 265) came from the date of production 2011, January month that I was fully arranged. Here I sfotkal the place of attachment of the nozzles from the automatic transmission to the radiator. In the old radiator, it can be seen that the tube is simply smooth, and in the new, with some kind of "ribs".
In order to change the radiator, it is necessary to start removing the bumper. Bumper is sooooooo simply, you need to unscrew the two screws from the wheels side, remove the grid of the radiator, and the bottom (on the bottom it is so to speak) to pull out plastic clips (there as clips in the clip are inserted, they are inserted in easily with nipples, the main thing is not to press them ), Then you need to disconnect the temperature sensor connector, and the hose from the headlight washers. After the screws are unscrewed, and the clips are removed, with one of the sides near the wheel cling to the hand and the bumper, it jumps out with the so-called. Clips, but then the case of technology. Put the bumper to the side, we climb to the radiator. There see the fan to be removed. It is attached on two bolts from above, unscrew them. Turn off the connector from it and pull out the fan up. Oh, yes, I almost forgot, you need to merge the cooler! I took a basin, substituted under the drain bolt (if you look at the car, then the left, the bottom of the radiator) unscrew it and waited until the liquid rises. After that, I began to remove the pipes. Because There is no puller for the Clamps of the Opolevskikh, I squeezed them with pliers, and to install it, I bought ordinary clamps under a screwdriver. We remove the two large nozzles and one thin, we unscrew the bolts that fasten the nozzles from the automatic transmission from the automatic transmission to 20, which fasten the nozzles from the automatic transmission, about 100 grams of dextro. Next, you need to unscrew the radiator of the air conditioner from the cooling radiator, it is attached to 4 bolts.
When you unscrew the last screw, the radiator with acceleration G will strive to fall on the floor, so that it does not happen to advise to take some wire thin and when you unscrew the upper bolts, link the radiator for the holes to the TV. But the task appears quite complicated enough, but solved. It is necessary to unscrew the so-called "ears" that keep the radiator from the bottom, more precisely on which it holds.
The "ears" hold on two bolts, unscrew them and the radiator can safely remove it to pull out down. For a new radiator, we rearrange all clips from the old one and in the reverse order. It suffered with removing the radiator of 2 hours, but it's all from ignorance, actually change the radiator simply enough.
If anyone has questions write! I will help with all I can.
