    Radiator for my 83 GMC 305 with a/c recommendations

    If you want OEM style, I had good luck with radiator.com looking for a new one for my 85 Chevy about 2 months ago. Found a copper core with brass tanks, 3-row. They also have aluminum ones. They are wholesale but sold to me a non-business. They have places all over the country. Follow...

    What have you done to your square lately??

    I used to have a piece of heavy packing foam about 18"X24"X4" thick. I cut a slot in it so it would fit over the hood latch. It worked great when I had to lay there while working on CUCVs in the military. Wished I had kept it now.

    Whatever brand you choose, be advised that you make sure they are DOT compliant.

    What new tools have you got lately?

    Finger getting squished is the reason I only use Vice Grip vice grips. When you push the release lever it moves away from the tool. Can't count the number of times using the cheap versions I have pinched the pad of my finger between the lever and the tool (I am a slow learner!)

    What have you done to your square lately??

    Put it through a rough work out. Drove it from Vancouver, Washington to Chugiak, Alaska, 2500+ miles over the Alcan Highway. Stopped between Watson Lake and Whitehorse and removed the brake light switch, took it apart, cleaned and reassembled it. Then I had brake lights again. Then about 100...

    What have you done to your square lately??

    Installed a new 3 core older style radiator. Found one in Portland, when I called on it I told them I would pick it up. 45 minutes later when I arrived guy said bad news they couldn't find it. Had them look again and back in the farthest corner of the place is where it was hiding. Pulled it...

    Refresh in near future

    I have done several that way over the years. Made them with long bolts and ground a hex head on the bolt shaft so I could use a wrench or socket to remove the guide bolt. You could grind a slot and use a screwdriver. I only put them in the lowest hole on each side that would match up with the...

    Engine cranks but no start

    No- take a CO2 fire extinguisher and spray the bottom of the tire to cool it down or pack it in ice and then go ahead and air it up! If that doesn't work, you didn't get it cold enough. :banghead:

    This blows...

    As long as you have a wastegate valve on it and you enjoy stopping at every gas station you see- go for it. Going to have to start with a fat wallet as it will be thin when you are done.

    Mounting fender emblems should not cause this much anxiety!

    3M tape works well, used it many times on vehicles. Clean area and back of emblem with alcohol, apply tape to emblem. Use blue tape to outline where it is going to be placed and stick it on. Might want to warm fender area first, not hot just warm. Hold pressure on it for a minute or so. You...

    What rear diff seals do I need to replace? Carrier bearing condition?

    The crud above the carrier bearing is most likely excess grease from the slip yoke. When grease is pumped into the yoke it comes out at the end and gets flung when driveshaft rotates. As for the carrier bearing it is usually a sealed bearing.

    Compressor not turning on.

    From what I have read online, if system is low on refrigerant, pressure is low and compressor won't kick on.

    Rotate 350 «backwards»

    In the past I have used a rag to pad a pipe wrench teeth's and tightened the wrench onto the bottom of the crank pulley. Tighten the wrench with the adjustable side on the outside of the pulley and the handle side inside. Then you can use the handle as a lever to rotate the crank.

    Need Help Understanding Belts on 86 5.0L C10

    Good to hear you are up and running. Don't forget to adjust them as they will stretch enough to be loose. There are plenty of videos on you tube that can help you diagnose the alternator issue. If it was charging before the belt change, check the tension of the alt. belt. From the top and...

    Need Help Understanding Belts on 86 5.0L C10

    If I remember correctly, I got to the rear adjusting bolt/nut for pump from under the vehicle and the one for the front is just below the top side of the pump. The belts kind of hide it from view. Feel around for it and you will find it. You may have to loosen the hinge bolt (far left of pump...

    Need Help Understanding Belts on 86 5.0L C10

    I have an 85 5 Liter and recently replaced all 4 of my belts. There are 2 smaller ones, 1 for the power steering pump below the A/C compressor and 1 for the air pump that is below the alternator. You will need to remove the other 2 in order to replace them. Yes, all the belts will come off...

    Intake manifold and stripped bolt

    I would use Permatex #2 Non-hardening instead of Teflon tape. Sealed a lot of machinery with that stuff, never had any leaks and was always able to take it apart later.

    Truck Overheating

    Do normal things as mentioned above like coolant level, radiator exterior clean and belts tight. Did you come back from your trip and drive up the same hill? If so, did it overheat on that trip? Going downhill with loose belts and backing off the throttle lowers the rpm and the water pump...
