Drive Clean, Drive Smooth: Hydro Flush’s Engine Performance Services

At Hydro Flush, we appreciate that your vehicle’s performance is a linchpin for both personal routines and commercial obligations. Whether overseeing a diesel lorry fleet or caring for a single saloon, diligent engine maintenance is key to securing maximum power, peak efficiency, and long-term reliability. That’s why we’ve tailored our expertise to meet your needs.

Our service portfolio includes gearbox maintenance, EGR valve restoration, and high-efficiency DPF cleaning using proprietary machine technology. Hydro Flush is positioned as your definitive partner in integrated engine cleanliness. We’re not simply addressing symptoms; our goal is to prolong engine life cycles, improve fuel economy, and reduce harmful emissions — all of which save you money in the long run through fewer repair costs.

Gearbox Servicing — Seamless Operation, Extended Durability

Your vehicle’s transmission is one of the most intricate and vital systems, responsible for transferring engine power to the wheels, regulating gear shifts, and optimising torque. Over time, grit, combustion by-products, and degraded lubricants compromise function, cause rough drivability, and risk severe gearbox failure.

Hydro Flush utilises advanced flushing systems and premium-grade lubricants to services gearbox, removing sludge, contaminated fluids, and internal debris in one comprehensive procedure. Our meticulous method ensures your transmission runs at a lower temperature, with reduced friction and enhanced operational efficiency.

Applicable to both manual and automatic gearboxes, periodic servicing at Hydro Flush prevents expensive failures and preserves your vehicle’s original performance characteristics. Including gearbox flushing in your maintenance plan is one of the most effective preventive measures against mechanical decline.

EGR Valve Cleaning — Improve Efficiency, Lower Emissions, and Extend Component Life

The EGR (Exhaust Gas Recirculation) valve is engineered to lower nitrogen oxide emissions by recirculating a portion of the exhaust gases into the combustion chamber, thereby reducing combustion temperatures. Over time, however, carbon deposits can block the valve, impairing airflow, creating a rough idle, increasing emissions, and triggering engine warning lights.

At Hydro Flush, we use specialised cleaning equipment to safely remove build-up without damaging surrounding systems — eliminating the need for costly replacements. Restoring the EGR valve’s airflow capacity helps maintain fuel economy, improves throttle response, and ensures continued compliance with UK emission standards.

By returning the EGR valve to manufacturer-level performance, your engine operates in a more balanced thermal state, delivering a smoother drive and extending the service life of associated components.

DPF Cleaning Machine — Restore Your Diesel Filter for Peak Performance

Diesel Particulate Filters (DPFs) are crucial in capturing harmful particulates and soot from diesel exhaust gases. However, over time, DPFs become clogged, leading to reduced engine power, poor fuel efficiency, and dashboard warning lights — often resulting in limp mode or costly repairs.

At Hydro Flush, our cutting-edge DPF cleaning machine thoroughly cleans the filter using high-pressure air pulses and controlled heat exposure. This process removes soot and ash, restoring up to 98% of the filter’s original capacity — all without damaging the filter structure.

Our DPF cleaning service offers more than just restored performance. It improves airflow, boosts combustion efficiency, and helps you avoid unnecessary replacement costs while extending the life of your entire emissions system.

Hydro Flush FAQs

Q1: How often should I service my gearbox?
A: For most vehicles, gearbox servicing is recommended every 30,000 to 60,000 miles, depending on usage and manufacturer guidelines.

Q2: Can a blocked EGR valve cause engine damage?
A: Yes. A blocked EGR valve can lead to higher combustion temperatures, pre-ignition, and long-term internal damage.

Q3: How long does DPF cleaning take?
A: Our professional DPF cleaning process typically takes between 1 and 2 hours.

Q4: Is it better to clean or replace a DPF?
A: In most cases, professional DPF cleaning is far more economical and restores up to 98% functionality, making replacement unnecessary.

Q5: Do you offer services for fleets?
A: Absolutely. Hydro Flush offers tailored maintenance packages for commercial fleets of all sizes. Get in touch to discuss your specific requirements.
