Welcome to our Crackley Garage information page about vehicle cooling systems. We hope you will find this site helpful. If you think it's a problem with your engine cooling system, please contact us immediately. Our experts will help you.

There is a radiator in every car equipped with a water-cooled engine. It consists of numerous thin tubes which are additionally provided with lamellas. As a result, the surface is enlarged, so that better cooling takes place. The cooling liquid is pumped by the water pump through this pipe system. Immediately behind the engine cooler, there is a blower, which is connected to the engine control if necessary. As a result, a constant temperature of the cooling liquid can be maintained.

An auto cooler can also get damaged. This is caused by the loss of cooling liquid. It is usually the case that a liquid pool has formed directly under the car. Due to the loss of cooling liquid, sufficient cooling of the motor is no longer ensured. The driver also detects this problem by the temperature indicator slowly approaching the red range. In this case, the cooler should be checked immediately. However, replacing a leaking engine cooler is not always necessary. Sometimes the leaking cooler can be repaired quite cost-effectively. Special sealants are offered for this purpose in specialised trade. This is a viscous substance, which is added to the cooling water. After the engine has run for a few minutes, the engine cooler is again sealed.

At our Crackley Garage workshop in Kenilworth, this would always be the first option to save our customers time and money.

Unfortunately repairing a leaking cooler is not always possible. First of all, it must be checked whether the cooler is broken, or whether it is merely a defective hose. This is not always immediately apparent. If a major defect has occurred, which cannot be rectified by simple means, the cooler must be removed. In our specialist workshop, the exact location at which the engine cooler is leaking is determined. These areas are then soldered. The engine cooler is then filled with high water pressure. In this case, no more water should escape.

In the case of older vehicles, it may be necessary to change the cooler due to material fatigue. In this case, repair is usually no longer possible. For replacement, our experienced mechanics need about 2 hours. After replacing the engine cooler, the coolant must also be replaced.

Please note, a cooler can also be broken if the antifreeze level is too low during the winter. Defects caused by frost can usually not be repaired. In such a case, replacing the cooler is usually the only option. Sometimes, a water pump replacement is also necessary. In the course of time, the antifreeze in the cooler loses its effect. Therefore, it is recommended to change the liquid at regular intervals. When the fluid is replaced, adequately, frost protection can be ensured.
