Application

This Tool Aid Cylinder Leak Down Test Kit, No. 33500, is used for engine diagnostics. It allows technicians to pinpoint internal engine failures — such as leaking head gaskets, worn piston rings, and defective intake or exhaust valves — without needing to tear down the engine first.

Features and benefits

• Diagnose internal engine problems like leaking head gaskets, bad rings, and defective valves
• Comes with a top dead center whistle that can be connected to the testing hose
• Dual 2-1/2" gauges with protective rubber boots read to 100 psi / 7 bar
• Test hose and gauges come with quick connect fittings for easy setup and use
• A 0.04″ orifice restriction fitting increases testing accuracy
• 24-1/2″ testing hose with 14mm end threads into 10mm,12mm, and 18mm adapters
• Comes packaged in a blow molded case

Selling points

• Comprehensive diagnostic power: Diagnoses the "Big Three" internal killers: gaskets, rings, and valves.
• High value-to-cost ratio: Provides professional-grade accuracy and a wide adapter range at a price point that appeals to both seasoned leads and entry-level techs.
• All-in-one solution: Unlike basic kits, this includes the TDC whistle and multiple adapters, meaning the tech won't have to go hunting for extra parts.
• Rugged portability: Packaged in a heavy duty blow molded case that looks great on a shelf and stays organized in a toolbox.
