Automotive leak detector that uses visible smoke to reveal faults across vehicle systems quickly and safely. Faster, less invasive diagnostics bring confidence to workshops and home mechanics when tackling intake, fuel or exhaust leaks. Is the GEARCELL 12V Smoke Machine Leak Detector the right addition to your garage toolkit?
⚡ At a Glance
- • Smoke Output: Visible column-shaped smoke, 8 L/min, ready in about 10 seconds
- • Best for: Mechanics and DIYers diagnosing leaks in cars, motorcycles, light trucks and boats
- • Not ideal for: Testing systems that require pressures higher than 15 psi or industrial-scale systems
Built-in air pump and smoke generator let tests run without an external compressor. Adjustable flow meter and pressure gauge help pinpoint leaks and estimate their size.
Pinpoint Leak Location - with column-shaped smoke and adjustable flow control
Column-shaped smoke is pushed into systems at a rate of 8 L per minute, with smoke generation beginning in about 10 seconds. The adjustable flow meter controls output for delicate or pressurised lines.
Visible smoke reveals the exact leak point so dismantling is minimised, saving time during diagnostics. Flow control reduces false positives when testing small lines.
Estimate Leak Severity - thanks to the integrated pressure gauge and 15 psi pump
On-board compressor generates up to 15 psi, while the pressure gauge shows pressure drops during testing. Separate air and smoke modes allow pressurising before introducing smoke.
Pressure readings make it straightforward to judge whether a leak is small or large, helping prioritise repairs. Quick assessment aids efficient workshop workflow.
Safer, workshop-ready operation - with thick-walled metal housing and overheating protection
Thick-walled metal construction provides durable, compact protection, and an integrated overheating protection system cuts power if operating temperature limits are exceeded. Smoke generation uses baby oil as the test fluid.
Durable build suits regular garage use while automatic shut-off reduces risk during extended tests. Using baby oil keeps generated smoke safe and harmless for routine diagnostics.

❓ Frequently Asked Questions
Q: What fluid should be used to generate smoke?
A: Only baby oil should be used, with 10–20 ml recommended per test, and a refill bottle is supplied, oil not included.
Q: Does the unit need an external air supply?
A: No, the built-in air pump supplies up to 15 psi, so external compressors are not required for vehicle testing.
Q: Is the smoke generation safe for workshop use?
A: Yes, smoke is produced using baby oil and the unit has thick-walled metal housing plus an overheating protection system that automatically shuts the unit off if temperatures get too high.
🏆 Our Verdict
Suitable for mechanics and home enthusiasts who need quick, visual identification of leaks across intake, fuel, exhaust and other vehicle systems. The combination of a built-in pump, pressure gauge and adjustable flow control makes diagnosing and estimating leak severity straightforward. While upfront cost may feel significant, durable construction and safety features make it a practical, long-term workshop tool.
