    Who knows auto insurance? Ins outs loopholes

    Here is a question (because I genuinely have no knowledge of this and hope never to need it): If you get hit by an uninsured driver, do you get penalized from using your UIM to cover the damage. Its standard practice that if you hit someone and your insurance pays, the insurance company...

    TBI Problems

    Low fuel pressure would make you go lean rather than rich in most cases (a lot of experience with THAT problem personally). The emission/drivability documents are essential reading since they are what GM published specifically for troubleshooting these systems. The only drawback is, in a lot...

    AC mismatch?

    The only way to know for sure is to thow a set of gauges on and actually measure your high and low side pressures. More likely is you have one or more failing o-rings in the system or a bad schrader valve slowly letting the gas leak down....

    AC Repair 81 C10

    Ouch. Thats what I expect mine to looking like when I get the point of working on the AC. You (and myself as well) are probably in for a new acccumulator/drier as well.....

    AC Compressor Constantly Running

    In a properly working system, as it gets cold the pressure on the low pressure side should decrease, and then the compressor will cycle. If the system has a problem that doesn't allow it to cool down enough that might not happen, which is why newer systems also have a high pressure cutoff on...

    What have you done to your square lately??

    Replaced the master cylinder over the weekend, went very smoothly once we found a bloody bench bleed kit (none of the 3 auto parts stores within the 30 minute travel radius had one!), but now I have a new problem again. My mechanic friend is pretty convinced one of the hard lines from the...

    Stolen truck found after 30 years

    I don't understand the logic in that - if it passes the sniffer and the emissions are within spec, why do they care HOW you get there? There is nothing magical about the original factory parts - that was what they used because that was what was available at the time. It seems counterproductive...

    Pressure Brake Bleeding Question

    Ahh good to know an affordable version exists. I assumed (and we all know how that goes) that since it was normally an aviation tool, the price would start at 4 digits and go up from there.

    Pressure Brake Bleeding Question

    I always wanted to try (but don't have anywhere near the kind of spare cash to buy) an aviation-style bleed system. From what I've seen on TV, planes bleed in reverse where you draw out the contents of the master, put pressurized fluid to the fitting down at the wheel and when the master is...

    27 FT Holiday Rambler

    I know my home thermostat does have a time out on the AC control so it will give the compressor about 15 minutes to bleed off before attemping to restart. Apparently you can smoke a compressor if you try to restart it while it still had residual pressure?

    Stolen truck found after 30 years

    I can understand the body and frame number check, but I'd be concerned if they reject a vehicle based on the engine number. On older vehicles, the odds of the engine/transmission not having been replaced at some point are pretty low. Are they just checking to ensure those components aren't...

    AC blowing off at compressor?

    So is it possible to add a high pressure switch to one of these compressors, or do you just need to get aa compressor that already had one? I'm pretty sure I need to just replace everything anyway, but I am curious.

    AC blowing off at compressor?

    That looks like the same type of compressor I have, and mine also does not have a high pressure cutoff switch, nor can I find any reference to one in the wiring diagram for my year truck. If it is something that can be added I'd really consider doing it because I experienced a blowoff event...

    Can you dig it.

    I kept the actual full power lighter in my British project car (which they label as for cigars in the owners manual - it may even get used to spark up a celebratory one if I ever get it finished) but the original ash tray was long gone and at $90 or so for a reproduction one its a low priority...

    Quick brake system sanity check?

    I've just started noticing a faint sinking of the brake pedal when sitting at a light. My suspicion is the master cylinder seals are starting to go and allowing fluid to blow by. I do not see any reduction of fluid level in the master, and do not see any leaks at any of the wheels or along the...

    New guy... LED issues

    LEDs can be fickle beasts, especially on these older machines that were built around incandescent expectations. Slight current leaks or grounds with any resistance would be completely invisible with incandescent bulbs, but they can cause LEDs to come on because of how little current flow it...

    Sanden AC compressor for Suburban with front and rear air

    Did you have to switch all your belt driven accessories to 8 groove belts to match, or were you able to find one with a 6 groove pulley?

    Sanden AC compressor for Suburban with front and rear air

    Icebox is definately what I want down here in Texas for sure - I know the mounting position of the factory compressor is frequently different between small block and big block vehicles - I'm trying to figure out if there is a specific bracket (or brackets) to buy that will let me use a Sanden...

    Time to fix my belt drive system.

    My 1989 Suburban with 454 was factory configured with a single serpentine, so getting the bracketry from a similar truck should let you to retain the serpentine system but in a properly designed configuration with a tensioner. The factory brackets place the accessories pretty similar to your...

    Sanden AC compressor for Suburban with front and rear air

    This is a topic I need to follow closely since I have effectively the same problem - 1989 with front and rear air, system pretty much dead although it will get slightly below ambient air temp but not much. I have the orig. style R4 compressor and want to go with a Sanden style because the R4 is...

    Temperature hunting at stop lights

    I don't know the 1987 belt configuration, but on my 1989 I had to have a reverse rotation clutch and fan. If the water pump is driven off the smooth (no grooves) side of a serpentine belt, its likely to be reverse rotation water pump and therefore need reverse rotation clutch as well. I looked...

    Temperature hunting at stop lights

    I have the factory pusher fan on my Suburban (1989 3/4 ton with the 454). Clutches (like fans) are directional, are you sure you have the one that matches the rotational direction of your water pump? The wrong fan was on my Suburban when I got it, so I had to triple-check both the fan blade...

    What have you done to your square lately??

    Had to pull the battery last night - wanted to run it up to the store and battery bad (showed 12.5V with everything off but just turning on the parking lights dropped it to less than 8V measured right at the posts). Hopefully there is still some warranty on it since its only 3 years old....

    Correct Gear Oil+

    In older British rear axles you have to be careful with GL4/GL5 as well for this same reason. The GL5 additive package is not kind to brass copper bronze etc, although Royal Purple claims their GL5 oils are yellow metals safe.

    Well that sucks

    You would never see the refrigerant as a liquid - its only liquid under the high pressures generated by the compressor and immedialy flashes off to vapor when moved to a lower pressure environment (which is how the system works - gas starts as a liquid, then flashes off in the...
