    The fan in the K5 does not blow the air out hard enough, is there a different fan that can be installed ie. from another type of vehicle that will work better? I checked all the ducts and the are in place but aren't sealed very well. I probably am losing some pressure form that. Any tips on what some of you huys have done would be appreciated.

    I split open the housing in the engine compartment , cleaned the evaporator coils , lots , and I mean lots of dirt came out . This improved my airflow through the evaporator tenfold . Made all the difference in the world . My big greenhouse of a truck feels good with the A/C on . Be careful when you do it . You can brush it and vacuum/compressed air it . Or you can buy a spray on cleaner that will evaporate at any A/C or appliance parts store . /forums/images/graemlins/k5.gif

    AC fans are the most "powerful" out there.

    There might be different fan motor part numbers out there, but if anything, on the AC/HD fan setups, its most likely the difference in where the cooling vent hole is drilled.

    That is basically all you can do without changing anything. I put a brand new evap in mine and I got a considerable amount of airflow increase after that.

    Where and how do I go about doing that? You are referring to the black box below the heater coil hose?

    If you have a non A/C vehicle the fan does not perform very well. Purchase a new fan motor for an A/C equiped vehicle they work much better.
