Nsfr1206 Posted July 1, 2021 Share Posted July 1, 2021 How can I get more air volume out of this ac? I know that coils need to be cleaned but does it work to add a booster fan inline somewhere or does that cause some problems with too much air across coil? Also it would be nice to reroute some air and build something to have it blow on my face more.... anybody tried this? I could build out of steel or maybe have a housing 3D printed.

tjc transport Posted July 1, 2021 Share Posted July 1, 2021 on both my 99 RD and the 05 granite, just cleaning the evaporator coil mad the difference of running the fan on high for so so AC with dirty coil to only running it on low for super cold in the cab. 1 Quote when you are up to your armpits in alligators, it is hard to remember you only came in to drain the swamp..

mrsmackpaul Posted July 1, 2021 Share Posted July 1, 2021 As already said, make sure the evaporatee coil is clean and once it is clean dont drive with window while the AC is going and it will stay clean for a long time Some times if the thermostat in the AC doesnt work properly thry will freeze up like a rock and slowly stop air flow Paul Quote Link to comment https://www.bigmacktrucks.com/topic/67182-mr-ac/#findComment-476195 Share on other sites More sharing options...

mrsmackpaul Posted July 1, 2021 Share Posted July 1, 2021 Pull it apart until you have good accessto the core and blow it out with a compressor Need to be careful of the fins as the compressor has enough air flow and pressure to bend them over and this will be just like blocking it again Paul 1 Quote Link to comment https://www.bigmacktrucks.com/topic/67182-mr-ac/#findComment-476208 Share on other sites More sharing options...
tjc transport Posted July 1, 2021 Share Posted July 1, 2021 i blow it out. then brush it off it with a soft bristle brush dipped in a cleaning agent solution like simple green or that purple stuff. this will break down any oily crap stuck to the core. then if possible rinse with clean water and let dry before reassembling. 1 Quote when you are up to your armpits in alligators, it is hard to remember you only came in to drain the swamp..

Thanks. Aren’t we on the same Ford forum? 🙂 Anyway, the MR is at Mack for other issues and when it gets back I guess I’ll tackle the ac. I moved that operator to a pump on a t800. Today was his first day with it alone and evidently something in the engine let loose and found it’s way into the turbo. Large invoice ahead. 😞 Quote Link to comment https://www.bigmacktrucks.com/topic/67182-mr-ac/#findComment-476225 Share on other sites More sharing options...

Dirtymilkman Posted July 3, 2021 Share Posted July 3, 2021 Also keep the pets out of the cab. Pet hair plugs them up tight. Quote Link to comment https://www.bigmacktrucks.com/topic/67182-mr-ac/#findComment-476321 Share on other sites More sharing options...
