Tire Sealant and Inflator Kit

The front-wheel drive MDX has increased cargo-carrying capacity and reduced weight thanks to an efficient tire sealant and inflator kit. This kit provides an easy and clean way to temporarily seal a small puncture or hole (3/16th of an inch or smaller) in the tire tread. Once injected into the tire, the sealant coats the inside of the hole or puncture, preventing air from escaping. The vehicle can then be driven (no faster than 50 mph) to a location where the tire can be repaired or replaced, depending on its condition.

The tire sealant and inflator kit can be used to add air to the vehicle’s tires in areas where compressed air is not available.

Using the Tire Sealant and Inflator Kit

  • With the vehicle parked outside, remove the kit from under the cargo area floor lid.
  • Attach the sealant/air hose onto the tire valve stem. Screw it until it is tight.
  • Insert the compressor power plug into the accessory power socket.
  • With the vehicle parked outside, start the engine. Keep the engine running while injecting sealant and air.
  • Turn the selector switch to SEALANT/AIR.
  • Press the inflator (ON/OFF) switch to turn on the kit. Until the sealant injection is complete, the pressure shown on the pressure gauge will appear higher than it actually is. After the sealant injection is complete, the pressure drops and then begins to rise again as the tire is inflated with air only.
  • Monitor the pressure gauge until the air pressure reaches 33 psi. To check the pressure, occasionally turn off the compressor and read the gauge.
  • Remove the power plug from the power socket and unscrew the sealant/air hose from the tire valve stem. Reinstall the valve cap.
  • Immediately drive the vehicle for about 10 minutes to distribute the sealant in the tire.

Frequently Asked Questions

Can I continue to drive on a tire repaired with sealant?

No, the sealant is only for temporary use and vehicle should be driven to an Acura dealer or tire repair facility as soon as possible so that the tire can be properly repaired or replaced.

Can I use the kit more than once?

The compressor can be used repeatedly; however, the bottle of sealant needs to be replaced after each use. The used bottle should be returned to an Acura dealer for disposal, and a new bottle can be purchased at the Acura dealer.

Does the sealant ever expire?

Yes, the sealant has an expiration date clearly marked on the sealant bottle, visible through an opening in the kit. Approximate shelf life of the sealant is 4 years.

Does the sealant work on all types of tire damage?

No, the sealant works on punctures or holes 3/16th of an inch or smaller. It cannot seal larger holes, or damage to the side walls of the tire.

Does the sealant affect the TPMS system in my vehicle?

No, the Acura tire sealant and inflator kit sealant will not affect the TPMS sensors or system in the vehicle (other sealants may, however). If the tire is repaired after using the supplied sealant, the sealant should be flushed from the TPMS sensor using cool water.
