    1976 C-10 Cooling Issues

    Rich will help the engine run cooler. Lean runs hot. I'd rather mine run a tad rich to help protect the engine.

    What have you done to your square lately??

    Instead of randomly placed trees and poles we now have piles of stuff in the rear view mirror. Oh, and I need one of those mirrors for my truck. One more thing to add to the list.

    electric choke connection without oil pressure switch

    I currently have the choke oil pressure switch bypassed like you mentioned. (I have the oil pressure gauge sender and a mechanical gauge connected to the engine and haven't had a chance to get another T to hook up the choke switch). The choke still works ok, I'm just careful to not turn the...

    My 1991 v1500 suburban

    I can't help with your steering box question but just wanted to say you've been doing a lot of work cleaning that thing up. I think a lot of people couldn't get past the clean up stage with mice.

    Roof rack mounts for 85 Chevy 4X4?

    Is there a style that grabs onto the drip rails? I seem to remember that was how roof racks worked back when all cars had drip rails.

    Need help, what model of 350 do i have?

    Not sure if it was the case back when these trucks were built but over 8500 lb trucks today have a different procedure for horse power testing. Under 8500 uses a transient sweep to measure max horsepower. Over 8500 uses a steady state test. Steady state test will show a lower hp due to the...

    Camaro tach that everyone can love.

    I picked up a Camaro cluster down in Georgia over Easter. I'm going to pick up a second Square Body cluster to do the tach conversion on and leave my original as-is. I'll take pics and post them up once I get into it.

    Looking at buying an 83 K10 with broken driveline

    I agree with everyone else. I wouldn't touch it unless you can get it for a body only price, assuming the complete drivetrain needs to be replaced. No way to really see how the engine runs, trans/tcase shifts, brakes work, suspension, etc. And assuming you wanted a complete project. I only...

    crew cab dually towing

    I found a 1986 GM towing guide online. It rates the C30 at 10k gross trailer weight for bumper pull, 12k for fifth wheel. Should be similar for your 89.

    TH400 - Harsh 1-2 shift, smooth 2-3 shift

    The Trans is the only thing not rebuilt when my dad went thru my truck. 1-2 shift is pretty harsh when accelerating or under load. It shifts smoother if I let off the gas. 2-3 shift is so smooth I can barely feel it regardless of throttle or load. Is there an adjustment for 1-2 shift...

    Intermittent Wipers-How do you know if you have?

    The intermittent wipers require a switch that has the intermittent position and then there is an electronic module that controls the power to the motor. The module is a little black box with silver heat fins on one side. The module plugs in between the wires in the column and the wires under...

    What have you done to your square lately??

    Started mine after sitting for 3 and a half months. No issues. Went and picked up our boat out of storage, about a 30 mile trip each way to get the truck loosened up after sitting. Tomorrow is about a 180 mile trip pulling the boat to sell it, then in two weeks will be the same long trip...

    I used to drive thru Jesup all the time. I was a co-op student in Savannah so I made lots of trips between Valdosta and Savannah. (and Valdosta and Atlanta and some between Atlanta and Savannah.)

    Oil, Filters, and Changes

    I tend to avoid these threads as they get pretty heated but I'm jumping in anyway. Diesel oil is designed to combat the effects of diesel combustion byproducts and blow-by which can be different from gasoline byproducts and blow-by. An oil analysis will give you many numbers two of which are...

    Reverse light switch missing... What??

    I'm not sure that the switch on the column is a Neutral safety switch, I think the safety is in the column and you can't actually turn the key with the auto trans shift lever in gear. The switch on the column works the reverse light because I had to adjust my switch to get the reverse lights to...

    Crooked bed?

    My bed looks crooked also. My plan, if I ever get time, is to park the truck on flat, level concrete. Then I'm going to start measuring the frame to ground on both sides, then bed to ground on both sides and bumper to the ground on both sides. With all those measurements I'll know if it...

    Does your ignition key...

    Growing up, my dad had an old square as a company work truck. I worked there a couple of summers. One time I had to make a run to the county dump which was a couple miles out of town. Jumped into the truck, started it up and drove out to the dump. Turned off the truck, unloaded. Got back in...

    HELP! How do I make sense of which bolts to use?

    Try threading the bolts into the locations by hand. It is very difficult to strip a thread by hand and most bolt sizes either thread in or don't. You can tell about how long a bolt to use by using a small rod to measure the depth of the threaded hole and then measure the thickness of the...

    What have you done to your square lately??

    Bought an early 80's camaro gauge cluster with a tach to use the tach in my truck. Will buy another square body cluster to modify and keep my original stock. I'm down in Georgia visiting my parents so I had to hit the junkyard.

    Tow power opinions *

    Not sure about earlier years or half tons but my '86 3/4 ton with heavy duty suspension and brakes with 454 and TH400 was rated at 10,000 lb. My boat and trailer are around 5500 lb and it tows that great. The boat is 24 ft long. My biggest concern is braking. The boat trailer has surge...
