Engine Treatments
Tec4 provides a complete range of engine treatments for preventative maintenance of a vehicle, with solutions designed to thoroughly clean oil systems, fuel systems, DPFs and cooling systems. For most garage customers, the best place to start is with a thorough engine flush, delivered as part of the overall service package.
Tec4 Oil System Cleaner, Oil System Protector and Top-End Treatment
Modern driving habits, extended oil drain periods and stop-start driving place a high demand on modern oils, leading to contamination build up on key components within the engine.
Tec4 has a complete solution to fight against contamination and keep engines cleaner for longer:
• Tec4 Oil System Cleaner neutralises acid, adds lubricity and dissolves contamination that has built up in the crankcase.
• Tec4 Oil System Protector reduces engine wear, inhibits contamination build-up and reduces oil consumption.
• Tec4 Top-End treatment helps reduce engine noise

Oil System Cleaner
• Neutralises acid
• Adds lubricity
• Keeps oil clean for longer

Oil System Protector
• Improves & Protects Oil System
• Reduces Engine Wear
• Reduces Oil Consumption

Top-End Treatment
• For Older Vehicles
• Reduces Engine Noise
Tec4 Petrol, Diesel and DPF System Cleaners
Both petrol and diesel consist of organic matter. Natural degradation and combustion of organic matter creates contamination which quickly builds up on key components within the engine affecting fuel injectors, inlet and exhaust valves and exhaust gas recirculation valves. This has a detrimental effect on vehicle efficiency. Tec4 has a comprehensive solution to help your garage fight against fuel system contamination.
• Tec4 Fuel System and Diesel System Cleaner products remove contamination and protect against future harmful build up. When added to the fuel tank, they add lubricity and clean contamination in the fuel lines, injectors, combustion chamber, inlet and exhaust valves.
• Tec4 DPF & Turbo System cleaner lowers the temperature at which soot particles can be burnt off, enabling the system to passively regenerate.

Tec4 Cooling System Cleaner, Degreaser and Improver
plus Radiator Stop Leak
Modern cooling systems are required to dissipate a significant amount of heat generated due to finer tolerances within the engine.
Oxidisation within the cooling system can quickly cause rust and limescale. When used at regular service intervals, Tec4 Cooling System Cleaner gently loosens and dissolves scale and rust from the cooling system.
Other contaminants often found in the cooling system include oil and grease, typically created following head gasket failure. Tec4 Cooling System Degreaser is a blend of biodegradable heavy-duty cleaners and de-greasers which combine to effectively break down and remove oil and grease deposits, improving heat transfer and enabling the cooling system to operate at maximum efficiency.
Another way to ensure that cooling systems are operating to their fullest capacity is with Tec4 Cooling System Improver, a highly concentrated and technically advanced formulation containing a blend of chemicals and corrosion inhibitors. These ingredients work together to improve lubrication, inhibit corrosion build-up and reduce the oxygen content of the coolant.
Our Radiator Stop Leak is designed to temporarily fix small leaks in the Radiator, Cooling and Heating systems.
