The two head supports are implemented with non-scratch plastic material and are adjustable from 0 to 30°. There are two handles for locking when the right inclination is set. It is also possible to regulate the horizontal position of the head moving the pins to the opposite holes up and down. There is a long regulation also for the push rod in case of deep valve chambers. The frame can be rotated 30° on both sides. Can also be regulated forward and backwards. In case of valves locked hard into the seat, hit the slide hammer on the top with a plastic mallet. The bench is also provided with a travel limit device that guarantees the same stroke for each valve. When the valve spring is compressed, the operator can block the position using the opposite pin. Consequently you can work on the valves having both hands free. Technical data: Dimensions: 785x500x625 mm Stroke: 265 mm Cylinder head: 750 mm Length: min. 185 mm Inclination angle = 0° - 30° Total weight: 25,5 Kg Application: Cars and commercial vehicles Full range of Govoni available - click to see the  Govoni Catalogue 2025 or Govoni Garage Equipment Catalogue 2025

A combustion leak tester is an essential diagnostic tool for detecting leaks between the combustion chamber and the cooling system - most commonly caused by blown cylinder head gaskets, cracked cylinder heads, or warped engine blocks.By analysing the gases in the cooling system, it identifies the presence of exhaust gases where they shouldn’t be, giving a fast, reliable indication of engine health. Typical uses include: Verifying suspected head gasket failure. Checking for cracks in cylinder heads or engine blocks. Confirming internal coolant leaks before costly repairs. This test can save hours of troubleshooting time, reduce guesswork, and prevent unnecessary part replacement. Key Features of the XL Model Fast & Accurate Diagnosis – Quickly confirms combustion leaks without dismantling the engine. XL Chamber for Improved Testing – Larger test chamber allows for more accurate gas sampling. Quick-Connect Adapter – Compatible with models 33140000 and 331400V2 for easy integration into existing setups. Petrol & Diesel Engine Compatibility – Works effectively across multiple fuel types. Complete Test Kit – Supplied with both standard and sensitive reaction fluids to detect even the smallest leaks. How It Works Fill the tester with reaction fluid (standard or sensitive, depending on the test requirement). Connect to the radiator or expansion tank using the included quick-fit adapter. Run the engine - combustion gases, if present, will pass through the chamber. Watch for a colour change in the reaction fluid, indicating the presence of exhaust gases. Replacement Fluids & Spare Parts 33194200 Reaction Fluid (Standard) – 250 ml bottle 33194400 Reaction Fluid (Sensitive) – 250 ml bottle 331942SP Standard Reaction Fluid – Pack of 6 331944SP Sensitive Reaction Fluid – Pack of 6 These replacement fluids are compatible with multiple SP Combustion Leakage Testers, including this HGV model.

A combustion leak tester is a crucial diagnostic tool for detecting leaks in the sealing between the combustion chamber and the cooling system - most often due to blown cylinder head gaskets, cracked heads, or warped engine blocks. By sampling the gases in the coolant, it quickly and reliably indicates whether exhaust gases are infiltrating where they shouldn't be, instantly helping identify the root of engine issues. Ideal for heavy-duty applications, this tool saves diagnostic time, prevents expensive misdiagnosis, and helps protect against unnecessary disassembly and repair. Key Features of the Universal HGV Model Fast & Reliable Diagnosis – Quickly spots cylinder head gasket and combustion chamber leaks. 25–50 mm Cone – Universal fit across a broad range of HGV (Heavy Goods Vehicle) inlet sizes. Dual Fuel Compatibility – Works seamlessly with both petrol and diesel HGV engines. Complete Testing Kit – Comes with both standard and sensitive reaction fluids for precise leak detection in varied conditions. How It Works Prime the tester with standard or sensitive reaction fluid depending on the degree of sensitivity required. Attach the cone to the radiator or expansion tank opening (25–50 mm). Run the engine to allow any combustion gases to pass into the tester. Monitor the fluid for a visible color change - if it changes, a combustion leak is present. Replacement Fluids & Spare Parts 33194200 Reaction Fluid (Standard) – 250 ml bottle 33194400 Reaction Fluid (Sensitive) – 250 ml bottle 331942SP Standard Reaction Fluid – Pack of 6 331944SP Sensitive Reaction Fluid – Pack of 6 These replacement fluids are compatible with multiple SP Combustion Leakage Testers, including this HGV model.

A combustion leak tester is a vital diagnostic tool used to detect breaches between the engine’s combustion chamber and cooling system - typically caused by blown cylinder head gaskets, warped blocks, or cracked cylinder heads. It works by sampling coolant and revealing the presence of exhaust gases via chemical reaction, making it a trusted asset for accurate, rapid engine diagnosis. Ideal for both petrol and diesel vehicles, it helps mechanics save time, avoid unnecessary disassembly, and reduce misdiagnosis. Key Features of the Standard Model Rapid Diagnosis: Quickly identifies combustion gas leaks to pinpoint cylinder head gasket failures. Versatile Connector Compatibility: Features a quick connector compatible with Sykes-Pickavant cap adapters (315, 316, 317 series), enabling flexible fit across multiple vehicles. Dual Fluid Sensitivity: Supplied with both standard and sensitive reaction test fluids allowing for accurate detection under various conditions. Fits Petrol & Diesel Engines: Suitable for testing across a range of vehicle types and fuel systems. Refillable & Reusable: Compatible with separately available replacement fluids in both standard and sensitive formulations How It Works Prepare the tester with either standard or sensitive reaction fluid depending on how much sensitivity is needed. Connect the quick connector to the radiator cap or expansion tank using a compatible adapter. Run the engine to let any combustion gases pass through the tool. Observe the fluid - a visible color change indicates combustion gases have entered the cooling system, confirming a leak. Replacement Fluids & Spare Parts 33194200 Reaction Fluid (Standard) – 250 ml bottle 33194400 Reaction Fluid (Sensitive) – 250 ml bottle 331942SP Standard Reaction Fluid – Pack of 6 331944SP Sensitive Reaction Fluid – Pack of 6 These replacement fluids are compatible with multiple SP Combustion Leakage Testers, including this HGV model.
