CFTNSXND Automotive Smoke Tester 12V — Complete Kit with Accessories & Starter Smoke Fluid, Built-in Pump

CFTNSXND Smoke Tester Automotive is a compact 12V leak-detection kit that produces dense smoke quickly and includes all accessories and a bottle of smoke fluid for immediate vehicle system troubleshooting.

This smoke machine is built for diagnosing leaks across many vehicle systems—EVAP, intake, crankcase, exhaust, cooling, EGR, vacuum lines and low-pressure turbo circuits—without needing an external air source. The unit features a built-in air pump, pressure gauge, instant warm-up, safety overheat protection, and a starter bottle of smoke fluid so you can begin testing straight away.

How fast will this unit start producing smoke for a leak check?

The CFTNSXND tester heats up rapidly and begins emitting visible smoke in about 10 seconds when filled with the recommended 10–15 ml of fluid. Minimal setup and an included power cord with clamps let you connect to a 12V battery and get to work immediately.

• Typical warm-up time: ~10 seconds to visible smoke.
• Recommended fluid per run: 10–15 ml (max 20 ml).
• Requires a 12V DC power source; use a converter for 24V systems.

What vehicle systems and components can I test with this smoke machine?

This tester supports a broad range of applications for cars, motorcycles, ATVs, light trucks, boats and other small-engine vehicles. It’s useful for locating leaks in fuel tanks, intake manifolds, vacuum hoses, crankcases, exhaust seals and low-pressure turbo lines.

• EVAP system and fuel tank fittings.
• Intake, vacuum lines, and intake gasket sealing.
• Crankcase and EGR system leak detection.
• Low-pressure turbo, exhaust, and pipe-fitting diagnostics.

What accessories and safety features are included in the kit?

The package ships with a complete accessory set: multiple cone adapters, delivery hose, intake bladder, cap plugs, clamps, and a spare bladder plus one bottle of smoke fluid. Built-in protections and operational notes help prevent overheating and damage when used as instructed.

• Included: adapters, hoses, pressure gauge, clamps and smoke fluid.
• Built-in air pump removes the need for external compressors.
• Overheat auto-shutdown protects the unit during extended use.

How should I operate and maintain the smoke tester for best results?

Fill the fluid reservoir only when the unit is cool and never exceed the 20 ml maximum. Use recommended mineral oil or baby oil, monitor oil level before each run, and allow cooling before refilling to avoid dry burning and thermal shutdown.

• Fill 10–15 ml per test; do not exceed 20 ml total capacity.
• Do not add fluid while the unit is operating; refill only when cooled.
• Operate outdoors or in a well-ventilated area to disperse odor safely.

Who is this for: Technicians, mobile mechanics, DIY enthusiasts and fleet maintenance teams who need a portable, all-in-one smoke solution for pinpointing leaks quickly. It’s ideal for anyone servicing 12V vehicles who requires a ready-to-use kit with accessories and safety features included. Note: this unit is designed for diagnostic purposes; follow all safety instructions and vehicle manufacturer guidelines when connecting to power and introducing smoke into vehicle systems.
