The ALT400 Automotive Leak Detector is a professional-grade smoke machine tester designed for fast, accurate leak detection in intake, fuel, coolant, exhaust, and EVAP systems. Featuring dual-mode testing (smoke + air pressure) and a built-in air pump, it eliminates the need for external compressors, saving time and cost. Generates dense smoke in under 5 seconds for rapid diagnostics, with auto-shutoff safety and IP54 waterproofing for shop durability. Compatible with cars, light trucks, ATVs, and marine engines, it’s the ultimate tool for emissions testing, preventive maintenance, and repair efficiency.
Features
Comprehensive Leak Detection
Conforming to SAE standards, it is designed for detecting the leakage of automotive pipe systems, such as air intake system, coolant tank system, fuel, exhaust, EVAP systems and so on. Dual-mode detection (smoke + air pressure) for pinpoint accuracy.
Rapid & High-Efficiency Smoke Testing
Generates dense smoke in <5 seconds for instant visibility. Fills pipelines in ~1 minute (with proper sealing). Identifies leaks within 3 minutes, speeding up diagnostics. It can produce smoke fast with large volume, which can effectively help the technician improve working efficiency on repairing the part where leakage exists.
Built-In Air Compressor & Smart Safety
Integrated mini air compressor for on-demand smoke generation. Overheat protection (auto-shutoff at 75°C) and anti-freeze design for all-environment use.
User-Friendly Operation
Intuitive interface + hanging hook for easy handling. Includes tapered + inflatable adapters for universal fitment. Pressure gauge enables quick leak diagnosis.
Upgraded Smoke-Oil Canister
Seamless, leak-proof design prevents oil spills. Optimized heating system ensures stable temperatures and safer operation.
Leak Quantification & EVAP Mode
Measures leakage quantity for precise repair assessments. Dedicated EVAP system test mode for emissions compliance checks.
Lightweight & Self-Contained Operation
Built-in air pump eliminates need for external compressors, reducing setup time and clutter. Portable design ideal for mobile technicians and tight work space.
Universal Vehicle Coverage
Tests leak-prone systems across cars, motorcycles, ATVs, snowmobiles, light trucks, and marine engines (speedboats). Adaptable fittings ensure compatibility with both common and specialty vehicle types.
