Find Intake, EVAP and Exhaust Leaks With Smoke From a 12V Battery
The T80 is an entry-level smoke leak detector with a built-in air pump, so it needs no shop air supply. It runs from the vehicle’s 12V battery and fills the line under test with smoke so leak points show clearly.
- Built-In Air Pump
- DC 12V Battery Powered
- Overheat Auto Shutoff
- Intake, EVAP, Turbo & More
Key Features
-
No External Air Needed
The built-in air pump and smoke generator work without a separate air unit, which suits mobile repairs.
-
Many Systems, One Tool
Test the intake, crankcase, EVAP, turbo, exhaust and cooling systems, as well as seals.
-
Overheat Protection
If the detector exceeds its working limit, it cuts the power automatically; operate it again later.
-
Hang It Under the Hood
A hook holds the detector in the engine compartment during testing, and a work indicator lights while it runs.

- Open the lineDisconnect the pipe that will be connected to the detector and attach the smoke output tube.

- Find the leakIn about 30 seconds the pipe fills with smoke. Look for escaping smoke, using a headlamp if needed.
Good to Know
Caution
- Power the detector only from a 12V battery; too much current will damage it.
- Fill 10–15 ml of oil at a time and never more than 15 ml; overfilling leaves no space to produce smoke.
- Do not run the detector for more than 8 minutes continuously; let it rest between runs.
- The round part of the detector gets hot; avoid touching it to prevent burns.
- Keep smoke away from smoke-sensitive parts during testing.
Care
- Top up with fresh oil only when the smoke gets thin.
- Pour out the old oil before refilling, and replace the oil regularly.
