Product Information

Are they loose?Remove injector clamp bolts and clamps. These are stretch bolts, so single use. They can stretch further over time, allowing the injector to ‘chatter’ under the clamp.

Seat repair:When the injector seat in the head is contaminated or damaged, it can be cleaned or refaced by inserting a special cleaning or cutting tool down through the injector opening to re-create a flat, sealable face for the new sealing washers. Fuel injectors are also known as injection valves. Comprising a valve and an atomising nozzle, injectors feed fuel into the combustion chamber of each cylinder. That's a vital role, because the engine requires the right combination of fuel and air to function.Seals and washers play a crucial role in the correct running of high-pressure systems. For instance; with every new injector kit you will have a soft copper washer - actually, it's a high-pressure seal. Moment of truth: The injectors should now come out with a good wiggle and some persistence, but they can be very tight if they suffer from carbon build-up or swollen tips. Torque matters: The clamp bolts are stretch bolts, so correct and accurate tightening is critical. When set, they stretch a set amount, but remain elastic. Torque first to 8Nm. If your vehicle's engine has started misbehaving in certain ways, it may need replacement fuel injectors.

Cleanliness within the fuel system is critical so, after removing pipes and components, ensure dirt cannot enter the resulting openings. The injector holes in the head also need to be cleaned to prevent dirt dropping into the engine, as explained in the captions.

Code work: Using general diagnostic software, code the injectors to the car. You need to input the four unique codes for the injectors. You did write those down, didn’t you?

Where are they?The 2.4 Puma engine bay: like all modern cars, the injectors are hidden under the plastic cover. Two bolts, off it comes, and we can see everything. Acontemporary diesel engine relies on high-pressure injector technology, and the Puma engine is no different. This Ford in-line four-pot diesel originated in the Duratorq TDCi for the Ford Transit, but it was used by several other manufacturers, including Land Rover in the Defender from 2007. If you're an older motorist, you may associate the job of feeding fuel into the engine with the carburettor. However, fuel injectors have been gradually taking over from carburettors since the 1990s. They're simply cleaner and more efficient. How to spot a faulty fuel injector
