A complete step-by-step walkthrough for testing engine air quality using the activator fluid sampling kit.
Remove the oil dipstick and use it to measure the sampling tube. Position the sampling tube so the end sits 1 inch above the max oil level mark. Slide the rubber ring up the tube until it rests just below the dipstick handle.
Ensure the tube end is precisely 1 inch above the max oil mark for accurate sampling.
Insert the sampling tube into the dipstick tube until it reaches the rubber ring. If it stops early, don't force it. Find the arrow on the blue-capped glass vial and lift the cap by pushing up at the arrow.
Never force the tube — if it stops before the rubber ring, the path may have a slight bend.
Pour the fluid from the glass vial into the test vial. Since it drains slowly, insert the glass vial into the test vial and tap the back to help it flow. Attach the test vial to the sampling tube, insert the syringe into the top, and place the vial in a safe spot away from the engine.
Keep the assembled unit stable and away from engine heat sources.
Turn on the vehicle and let it idle for 10 minutes. In freezing temperatures, drive the vehicle before the 10-minute idle. After 10 minutes, shut off the vehicle.
For diesel engines, drive the vehicle for 10 minutes before testing. After driving, let the engine idle for 2 minutes, then shut it off.
Use a timer to ensure an accurate idle period.
With the vehicle off, slowly pull the syringe plunger to draw 100ml of engine air up the sampling tube, bubbling it through the Activator Fluid. Do this gradually.
Pull the plunger slowly and steadily — rushing can cause inaccurate results.
Transfer the Activator Fluid from the Test Vial into the 1.5 ml Viewing Vial. Shake for 10 seconds, then compare the colour to the chart provide.
Shake thoroughly for a full 10 seconds to ensure even colour distribution.
