    Does the person filling your LP tank really know what they are doing?

    This is not uncommon. Even at a Flying J where you would think they would be experienced I have had to tell them to open the vent before starting the pump. I never fill my tank unless I carefully watch them doing so. I had to get the manager involved once when the filler refused to listen to...

    12pt inner drive bolt torque

    It has been pointed out to me by a very knowledgeable GMC owner that doesn’t post here that I had typed the part number wrong. It should be 394777. I somehow dropped off a 7. He also provided me a diagram that he had made of the bolt and washer many years back. I have posted it to the GMCMH...

    12pt inner drive bolt torque

    Jim Hupy — You are very positive in your reply but please show me anywhere it says they are different lengths. I have checked the maintenance manual and it doesn’t say anything about the length. It just says to use new bolts and torque them to 75 ft lbs. I checked the parts book 78Z and on...

    Rallies: what days of the week are best for people with J.O.B.s?

    Hi Karen The crates that we ship with our equipment has never been a factor in selecting a site. By having our own equipment we have found that we can keep the cost of a convention down considerably — much more than the cost of storage and shipping of our equipment. The main reason that we...

    Rallies: what days of the week are best for people with J.O.B.s?

    It just occurred to me that some of you might not be aware of and one thing that has not been mentioned here is that when GMCMI uses a convention site we tie it up for a lot more than the 6 days of our convention. For example the Tuscon convention will be held from Friday Apr. 6 to Thursday...

    Alternator

    That is also known as an Autolite DL7157. It has been sold by various auto parts suppliers including Checker, Schucks, Kragen, and Murrays.. These companies were part of CSK which was acquired by O’reillys in 2008. Some of those names are still being used but are O’Reillys. For example in Ft...

    Clubs Posting To GMC list

    Someone had earlier posted the question as to why more information is not being posted here about various GMC clubs activities such as rallies, schedules, etc. It has been brought to my attention that apparently the administrator of this site had decided some time ago that postings from Kim...

    Rallies: what days of the week are best for people with J.O.B.s?

    Carl If you read the reply that I sent to Karen you can see that the reason for starting on a Thursday (what you call a schedule shift) was not to accommodate working people who want to attend the weekend portion. If was done to allow us to basically find sites that would accommodate us. Over...

    Rallies: what days of the week are best for people with J.O.B.s?

    Karen Having managed the GMCM conventions for several years I can tell you that starting on Thursday was NOT an effort to get younger people to come to the conventions. Starting on a Thursday usually makes it possible to even reserve a site. That leaves a Fri, Sat and Sunday at the end of our...

    The stock temp gauge doesn't really tell you your operating temps. Why that's a problem

    Rob Just about any auto parts store in the US will take used antifreeze just as they will take used motor oil and transmission fluid. There are services that come around to auto parts stores and pump out their tanks of use material. Some even pay the store for it. Bob has already checked that...

    The stock temp gauge doesn't really tell you your operating temps. Why that's a problem

    The radiator cap should also be tested. Most only last about 2 years. The spring weakens as it opens and closes thousands of times on a trip. And the rubber seals deteriotate over time. I have a Stant pressure gauge that I use. It can also pressurize the radiator cold so it can be checked for...

    Can antifreeze/water freeze solid, and do damage at -25 when tested to +5?

    You might be confusing the definitions of eutetic point and freezing point. Not many people call it the eutetic point as it is commonly referred to as the freezing point. Each mixture of ethylene glycol and water would have different points. A 50% /50% would have a -34 F freezing point and...

    Can antifreeze/water freeze solid, and do damage at -25 when tested to +5?

    I would think it might depend on your definition of damage. You are not likely to crack a block but you might pop out the freeze plugs which can be a bit of a job to replace. Emery Stora > > Emery, > > Thanks for setting us straight. From long ago, I recall that if you are protected to...

    YES Emery Stora > > I've never thought about this before. The neighbor that lives across the street is serving in the Middle East now. I got an e-mail from him about his truck that's sitting outside. He thinks the antifreeze is at +5. Our highs for this next week are to be between -2 to -10...
