    Hey all,

    About a month back I had my truck in the shop and they filled up the AC coolant and checked everything out. Well, today was a REAL hot day, around 101. Was driving around town in stop and go traffic and my AC would cool, but it just wasn't doing the job. I even had it on full blast with recirculation. Any suggestions? Thanks

    If they put dye in it, then the shop should try to find the leak for free. Take it back to them and see what they say.

    Hey mann, i'm in the Temple area. the air in my 03 is pretty good at best, maybe once a week i notice it seems to do really well. remember that the outside air must move through the grille and condenser fast enough to cool it down. in stop and go, it is tough for your system to cool. these trucks dont have a seperate fan to suck air into the grille just for the ac like most. these systems are very sensitive, if everything is not just right, it wont perform well.

    View the build. Too much to list.
    Trying to cool air over 40 degrees in a second is like sarah palin shutting her mouth. It just doesn't happen.

    one suggestion would be to put a thermometer in the supply vent next time you suspect a problem and see what your discharge air temp is inside the vehicle. Also check the temp where the return is and then subtract the 2 and you have your Delta T. This can help determine the performance of the system.

    all those above are mentioning good things. there are other factors in affect too. may need to have it back in the shop for another check. if you want to nail them down when they check it, have them tell you the high and low side pressures. and also ask them what the spec is for these pressures for your truck at idle and also at cruising speed. this will force them to give you definate data and not just tell you they think it is better.
