Diesel Specialist Staffordshire – G.W. Dale Ltd

We are a diesel engineering company specialising in diesel injector and fuel pump repairs located in Stoke on Trent, we were established in 1961 and still remain in family ownership today.
We pride ourselves that we are small enough to care but experienced enough to cope with any aspect of diesel engine technology. Whether it be the most modern systems in use on diesel engines today, such as the common rail system or the legacy systems of older vehicles, heritage narrow boats or off highway machinery.

Manufacturer Approved Service Centre

As a Delphi and Bosch authorised workshop, we are trained and equipped to the exacting standards you would expect from a major original equipment manufacturer.
We are able to provide service and repairs on the full range of Delphi, Bosch, Siemens and Denso diesel products whether fitted to cars or light vans, trucks, tractors or other off-highway equipment, industrial or marine applications.

Diesel Engine Pump Testing & Repairs


All of our technicians are time served and fully qualified, our staff are on a rolling training program to ensure the skill base of the company is kept as up to date as possible.
Training is carried out at Manufacturer Approved Training Centres where the technicians receive certification on successful completion of their course.


Where possible we use manufacturer reconditioned parts, not only does this help us keep the cost to our customers as low as possible it also helps protect the environment too.
By having the injectors serviced on a high mileage diesel vehicle you can help the environment too, as this reduces emissions and increases the fuel economy of the engine.

Car Servicing

Comprehensive car servicing means peace of mind for you, ensuring your car is kept in tip-top condition all year round. Annual servicing is strongly recommended to keep your vehicle roadworthy and is often a manufacturer’s requirement to keep your vehicle’s warranty entact.

It’s often a good idea to get a car service at the same time as your MOT so that you can get any problems fixed before having the test. We can put your vehicle in for the MOT as well.
