What It Is / How It Works

This is a car smoke leak detector, a smoke machine style tool for finding leaks in vehicle pipe systems. It is made for pipeline leak detection on cars, motorcycles, snowmobiles, ATVs, light trucks and speedboats.

The package lists a main unit, a power cord clamp, a standard cone adapter, an airbag, a hard rubber hose plug and a user manual.

Who It's For / Use Cases

Car and motorcycle owners and repair shops who need to find leaks in pipe systems suit this kind of smoke tester. It is useful when a vehicle shows pressure or vacuum faults and the pipework must be checked. Technicians checking intake, exhaust, cooling, fuel tank or EVAP lines use smoke testing to pinpoint where air escapes.

How to Use / Care

1. Use a head lamp if you need extra light to check the leak points.
2. On first use, fill the detector with 10 ml (0.34 US fl oz) of oil.

How to Choose

Choose a smoke tester based on the pipe systems you need to test and the power you can supply. This unit runs on a DC12V battery, so confirm you can connect it to a 12V source before you start a test.

Oil is the other selection point. Baby oil, olive oil or liquid paraffin are the listed options for the testing liquid.

Frequently Asked Questions

How long can the detector run?
Do not run it over 8 minutes continuously. It needs interval rest between runs.

What oil does it use?
Baby oil, olive oil or liquid paraffin can be used. The first fill is 10 ml (0.34 US fl oz), and each refill can be no more than 20 ml (0.68 US fl oz), added only when the smoke gets thin.

How soon does smoke appear?
It outputs thick smoke within 30 seconds after you connect the DC12V battery and turn it on.

Does the unit get hot?
The round part of the detector gets hot, so take care to avoid burns. If it exceeds 75 ℃, it turns off its power automatically.

What if a test pipe must be disconnected partway through?
Secure the other side with a rubber stopple, as the source instructions advise.
