SERVICES WE PROVIDE - Cylinder Head Pressure Test

Pressure Testing is often used to find problems with cylinder heads or blocks within your engine. This method saves a lot of time and allows us to identify what faulty components you have. Therefore we can diagnose what needs to be done in terms of repairs to the cylinder head.

Cylinder heads can be cracked in many ways. They can wear out or can crack due to overheating in the engine, or through a cooling system failure. When this happens, we provide a quick and reliable pressure test. We highly recommend them as they allow us to find internal or external faults.

During pressure testing, we blank water outlets on the cylinder head and then put pressure on with compressed air. As a result, we can see if the cylinder head is leaking.

Come Visit Leun Seng to have your engines checked or rebuilt.

我们提供的服务 - 汽缸盖压力测试

压力测试通常用于寻找发动机内汽缸盖或缸体的问题。这种方法节省了大量的时间，并让我们能够确定哪个部件出现故障。因此，我们可以诊断需要用什么方法来维修缸盖。

汽缸盖的破裂方式有很多种。它们可能会因发动机过热或冷却系统故障而磨损或破裂。当这种情况发生时，我们会提供一个快速和可靠的压力测试。所以我们强烈推荐在进行维修前先通过压力测试，因为这可以让我们发现内部或外部的故障。

压力测试时，我们会将汽缸盖上的出水口堵住，然后再用压缩空气加压。最后，我们就可以看到汽缸盖是否有泄漏的情况。

赶紧来聯成询问有关于引擎检查或重建吧。
