OTC 6521 Smoke Machine – Auto Specialty Tool

OK, so this smoke machine is an automotive specialty tool for Evaporative leak testing and not the type of smoke machine your kids will be wanting for Halloween. But, we have a great deal on the OTC 6521 smoke machine and decided to add it to our first annual Halloween, automotive tool sale. It’s on sale with free shipping and no sales tax charged outside the state of Florida (see current listing).

Engine Fault codes like P0440, P0442, P0455, P0456 and P0457 can be caused by EVAP system leaks. And for those pesky Evaporative codes, nothing beats having the right tool for the job. Leaks are the most common cause of EVAP codes and if it’s not just a loose gas cap, the OTC 6521 will provide a quick easy way to find the source of the leak.

Vacuum Leaks can also be traced easily with the OTC 6521 smoke machine. Fault codes for lean conditions like P0172 and P0174 are typically due to a vacuum leak. If the vacuum leak isn’t a huge obvious hissing leak, then a quick smoke check with the OTC6521 smoke machine will make short work of finding the source of the problem. Just remove any engine vacuum line and block off the throttle body and the smoke will reveal the leak.

Smoke Testing directions using the smoke machine can be viewed in much more detail in our exclusive tech article. The adapter cones that come with this smoke machine will allow much versatility when attaching the machine. Exhaust leaks are easy to find by using one of the included cones to attach to the tail pipe (after the car has cooled off). This is a particularly good test when a cracked exhaust manifold is suspected. So, why not consider a smoke machine for year round use? This smoke machine not only makes smoke, it makes money!
