    A/C upgrade

    You can order a Sanden with the same connection as currently on your GMC. Then buy tees for rack line and run hoses to the new inside evaporator. They run well in parallel. Emery Stora > > Okay, the dash a/c sucks and I’m going to add an additional Vintage Air slimline under dash unit. Also...

    So What charges What in battery land

    Yes, the alternator charged both banks through the battery isolator or by means of a combiner. The Onan provides 120 volts to the converter (battery charger) which generally only charges the house battery bank. However some converters have the ability to charge one or two more banks while...

    76 Birch air conditioning - I'm going in

    Jon How would it be a $40 charge. If you use the recommended 3 cans at $6.99 per can it would be a $20.97 charge? If you put in $40 worth you are overcharging the system. Emery STORA > >> Dave, >> >> You are gambling with $40 worth of duracool. >> >> Then pop on a can, fire up engine...

    76 Birch air conditioning - I'm going in

    James I still have to disagree with you on this. If you go to www.duracool.com in their technical facts area you will find the statement “compatible with mineral and synthetic oils including PAG and ester oils”. I am very familiar with PAG and I have been installing Duracool in GMC Motorhome...

    76 Birch air conditioning - I'm going in

    James Duracool is compatible with the oil used with R12 and also compatible with the oil used with R134a. If the system was properly converted for R134a then Duracool can be installed without changing anything. Emery STORA 77 Kingsley Frederick CO > > If you have R-134a, and it was...

    Multiviscosity oils

    I have recently been asked questions about multi viscosity oils and viscosity modifiers. Specifically how do synthetics get to be multi-viscosity without reducing the lubrication content and why you don’t see single grade synthetics. I wrote a Tech Bulletin when I was the Tech VP of Western...

    Awning protection from door?

    Rick I also screwed a small wheel in a bracket to the corner of the door. Prior to that I reversed the awning rail to put the groove at the top. This helped by raising the awning. I was able to use the same screw holes. Emery Stora 77 Kingsley Frederick CO > > My P.O. just screwed a small...

    LiFePo4 Below Freezing Temps

    I believe they can still be charged if you reduce the charging rate. How do they charge electric autos at low temps? There are also new lithium batteries that automatically heat the batteries at low ambient temps. Emery Stora > > Guys, > > I was all in on LiFePo4 Batteries until I...

    module for low water light

    I think the low water level light was only on the 77and 78 GMCs. I know there is a probe in the back of the radiator but where is the module located? My light comes on all the time and I am trying to find the problem. The wire is connected to the probe. Emery Stora emerystora

    Dash air conditioning

    I had purchased a Sanden SD7 model 4434 from Applied GMC. The fitting on the back of it exactly matches the GMC hoses. No retrofitting required. It bolts right into place. The compressor came with mounting brackets that bolt to the front of the head so it eliminates the GMC bracket that goes...
