Recharge Air Conditioning with Freon in a Toyota Tundra
June 06, 2013
Recharge Air Conditioning with Freon in a Toyota Tundra - Look at the air conditioner lines for leaks and damage. Replace or repair any damaged parts before you continue with the recharge. You can use a leak detection kit if desired.Find the Low Pressure Side port connector. It is near the firewall on most Toyota Tundra trucks. This location may vary in some Tundra trucks. It will have a yellow cap marked LOW. Take this cap off and put it in a safe place. You will have to replace it later.
Turn on the engine and set the air conditioner to the coldest setting. You also need to have it blowing as hard as possible. Check the pressure in the air conditioning system using an automotive air conditioning pressure gauge, available at most automotive stores. This allows you to get a valid pressure reading. If the pressure is above the acceptable range, recharging the system may cause an explosion and you should take your Toyota Tundra to a mechanic for service.
Connect the refrigerant according to the kit directions. Allow the air conditioning system to empty the can. You should check the pressure often to make sure it stays out of the dangerous levels. It can take as long as 10 minutes for the can to fully empty.
Recheck the pressure. If it is still below the normal range, add more refrigerant. Make sure that you check the pressure often after you begin a new can to keep it out of the dangerous level.
Sometimes, if your air conditioning system is working properly, adding refrigerant is all that is needed to correct the problem of warm air blowing. You can use an R134 automotive recharge kit from your local automotive store to do this. In some areas, you may need a license to purchase refrigerant. - by eHow
