It presents a color-coded readout indicating “good,” “bad,” or “low,” plus an LED indicator for recharge or replacement needs. It typically costs under $7 and is small enough to live in a trunk or glove box. Some users caution that it measures voltage rather than amperage, which can influence readings in certain scenarios.
icon Diagnostic smoke Machine
To pinpoint leaks in intake, cooling, EVAP, or exhaust systems, the Icon Smoke Machine pumps visible gas into the system and highlights escape points. The unit runs off the car battery and an air compressor, delivering up to 150 psi and offering adjustable flow for precise leak pinpointing. at about $570, it’s a considerable investment, but many users praise its portability and diagnostic reach, noting it can identify leaks that affect engine performance. The tool includes extra features like an LED flashlight and a hook for hood mounting, making it a common pick for shops and serious DIYers.
Central Machinery 6-Liter Ultrasonic Parts Cleaner
Cleaning tiny engine parts can be tedious, but an ultrasonic bath can dramatically reduce scrubbing time. the Central Machinery cleaner uses 40 kHz waves to loosen deposits from carb parts, injectors, and other small components, while a digital control panel handles heating and draining. Priced around $170, it’s praised for delivering gentler cleaning than manual scrubbing, though a few users report it doesn’t meet their expectations in every case. The cleaner is a practical complement to routine maintenance and can extend the life of small parts.
Britannica notes that ultrasonic cleaning relies on high-frequency sound to disrupt contaminants, offering a non-abrasive alternative for delicate items. Learn more.
Maddox MR16 OBDII Code Reader
The most feature-rich option in Harbor Freight’s lineup, the Maddox MR16, plugs into the OBD-II port and delivers advanced diagnostics on a 4.3-inch color screen. It offers 16 services, including calibrations, active tests, and system resets, plus maintenance schedules and recall notices. Bluetooth pairing enables smartphone or tablet connectivity, and the unit can store diagnostic histories. At about $249.99, it sits above basic code readers, justified by its enhanced capabilities and portability. Some users report occasional freezes, but overall reviews are favorable for its depth and usability. The device is compatible with most post-1995 passenger cars and hybrids and runs on three AA batteries.
