    Gasket dressing yes or no?

    This is another good example of why you should buy from a knowledgeable GMC parts supplier. You a can buy a filter from about any parts store in the USA or Canada. But does it work properly? Some have too small a pipe so they suck air into the transmission. Others are too short so they fall to...

    Dome/map lights not working.

    Deb The dome lights don’t work through any of the push pull positions of the headlight. When you rotate the headlight you can dim your dash lights. It you turn it all the way there will be a click and a switch will turn on the dome lights. (If the switch at the dome light is not in the off...

    Where do you live in Colorado. With that information it might be easier for someone to help. I suggest you put your location in your signature line. By the way I have a 77 Kingsley and it came from the factory with a 455 so you can’t assume they are all 403’s. Emery Stora 77 Kingsley...

    Replacing shore power cable

    I like my original cord. It looks like a 50 amp and has a 50 amp plug. But it is actually a cord marked 40 amp. A 50 amp cord is too thick and hard to wind. A 40 amp cord is plenty heavy and that is what GM supplied in the motorhome. Most people refer to it as a 50 amp. The circuit breaker...

    Anyone have any experiance with this Fire Extingusher

    These are not the ones that I was thinking of. Apparently this is a hand held extinguisher. There was an article in the FMCA magazine of something that looked similar. You mounted it in the engine or Onan compartment. It released by fire or heat. That is what I was looking into but have not...

    Anyone have any experiance with this Fire Extingusher

    Tom I have heard good things about them. Not only not having to protect from freezing but also no wiring or piping to hook up. I believe Bruce Hart and possibly Stan Edwards is using them. I have been thinking of buying some myself. Emery Stora 77 Kingsley Frederick, CO > > Stumbled across...

    More new engine follies

    Did you check the thermostat ? It sounds as if the stat is not opening. Put it in a pan of water on the stove with a thermometer (even a candy thermometer will work. ) Make sure it opens before it boils. Emery Stora > > After some thought, it behaves like there's a restriction or blockage...

    Clips for wire management windshield main support.

    Yes it does but there is room for more. I also had a CB antenna lead which is still there but no longer used. There is plenty of room for more wires. Emery Stora > > Yes, on my coach, it has an antenna on the roof. I put another one up there > for serious radio. Ran both leads through the...

    Centramatic wheel balancing system.

    Another thing to watch when a shop is doing your balancing. DO NOT let them use a cone to hold the wheel on the balancer. It will not work properly especially on Alcoa type wheels. They must use a lug mounted adapter. If they argue with you after they hav balanced with a cone ask them to loosen...

    Fuel tank selector valve

    Todd I have not heard that the fire was caused by gasoline in the motorhome. It was mentioned that there was a propane bottle near the part of the mobile home that was struck but I have not heard as to what caused the fire. What do you know about it? Have you seen anything more or are you...

    Centramatic wheel balancing system.

    I used Centramatic balances from 1973 to 1979 on my Dodge Travco. At that time they weee a round tube filled with oil and small ball bearings. They clipped inside the rim of my 17-1/2” wheels. Today they are on a disc which mounts behind the wheel lugs. I haven’t used the new style but the old...

    House electrical system not that complicated

    Jerry You should also include the fact that many of the new converters have separate outputs to charge two or three battery banks separately at the same time. When I installed my Xantrex TruCharge several years back I ran a wire from the second out post on my converter to the front engine...
