never heard of this. Dare I ask how you use it?
1. Remove your AC cabin air filters and replace the cover without the filters.
2. Raise the vehicle and remove the front skid plate to gain access to the AC evaporator drain… on the right side of the firewall above the right front sway bar body mount. This is a good time to check and see if the water draining from the AC evaporator has rusted out your swaybar mount. I’ll bet there is some rust… might think about an AC drain relocation kit.
3. Stuff the cone end of the AC cleaner into the AC drain, and shoot the whole contents of the can into the AC airbox. The Toyota instructions say shoot half the can and then repeat… I would shoot the whole can to ensure that the air box fills up to the point where all of the AC evaporator is covered in the cleaning foam.
4. I leave the cone end and AC cleaner can connected for 3 to 5 minutes to keep the cleaning fluid up in the air box and saturate the entire evaporator. Then remove the cone and let the influence drain into a pan… Let it sit for about 10 minutes to drip, and lower the vehicle.
5. Then you start the vehicle and turn the air conditioning on high and outside air. Let it run for about 10 minutes or more. What you’re doing at this point is washing the evaporator off with condensate generated by the air conditioner. After 10 minutes, turn off the vehicle.
6. They don’t tell you this, but on a hot day, I would run the climate control for another 10 minutes with the air conditioning off, so as to dry the evaporator.
Then you can use the air freshener part of the kit.
7. Start the vehicle with the climate control on high and air conditioning off, outside air, not recirculated. Then you spray the air freshener into the air intake grates next to where the windshield wipers bolt on at the cowl. Instructions are written on the can.
It most definitely makes a difference… After you’ve been using the air conditioner, and then run the climate control with the AC off, no more musty smell.
