Do not neglect the signs of a damaged diesel injector. When you are experiencing difficult car start ups, severe fuel leaks in the cylinders, and too much smoke from the exhaust, you have to act quickly and do the necessary repair procedure. The first step in fixing this problem is finding a replacement diesel injector. The task may be a little tricky if it's your first time to do this. To help you out, you can refer to the following tips on what you should do and what you should avoid when buying a diesel injector.
- Determine the right amount of flow rate that your vehicle requires to achieve its maximum efficiency. Flow rate is the amount of fluid that passes through the cylinders at a given unit of time. Diesel injectors come in different levels of flow rate, which are predetermined by the manufacturer. You have to bear in mind that the increase in horsepower and speed depends on the flow of fuel that the diesel injector can possibly allow.
- Choose a diesel injector that is made from the finest materials and components to be sure that it can last for a long time. The temperature inside the combustion engine can be extremely hot. Only prime metal types such as iron and steel can withstand that condition. That's why when buying, you have to watch out for the kind of metal used in producing the injector.
- When selecting a diesel injector, take in consideration the design of the injector's nozzle. It may not be obvious, but size and form of the nozzle and its needle affects the fuel flow rate. When looking for injectors online, carefully check the catalogues for information regarding the nozzle type.
- Do not buy from unauthorized dealers or resellers. It's highly advisable to buy from only trusted brands to be sure that you're not only getting a high quality injector, but also a product warranty. Diesel injectors are pricey; they cost a hundred dollars or more. Branded injectors have a heftier price tag, but you have to remember that you're also paying for the warranty, and this warranty is your protection in case you bought a wrong part or you got a damaged injector.
- Do not purchase a diesel injector unless it's an OE replacement or a direct fit. Remember that leaking fuel in the cylinders is a very common problem when the injector loosened and lost its proper fit in the cylinder. A wrong-sized replacement injector, even though it's new, may generate the same problem. Aside from fuel leaks, you'll also have a hard time installing it because you still have to cut or trim it.
