    Guess The Tool

    OK I was rebuilding a starter for my Sierra last week . GM put it together with Inverted torx screws usually you just get those with a 6 point socket but this one was recessed to deep. So this is a home made inverted torx bit made from a deck screw.

    Heater hose now connected to water pump - no heat?

    Since you dont have the extra port. That sounds like a logical solution. Yor heater would act like the bypass. Then just plug both water pump inlets.

    Heater hose now connected to water pump - no heat?

    Both your heater hoses are on the suction side of the water pump. Will not flow coolant through the heater core. It needs to draw coolant from the manifold.

    Location of heater and AC actuator?

    That actuator has 2 hoses going to it. H and I so test both sides of that one. Also where that actuator connects to the door there is a plastic piece 168 that is known to break.

    Location of heater and AC actuator?

    most of it is under the dash on the passenger side. Except the vacuum motor #266 is in the cowl behind the blower motor and the vacuum line E comes through the firewall from the engine compartment. Remove the glove box you wi get a better view.

    Power Steering with AC Bracket Question

    There are a couple variations in brackets. Your best bet is to get the other one from the donor. pay attention to the bolts / washers or you will have alignment issues to and the water pump might be drilled or threaded where the p/s pump mounts.

    Question about vacuum line for Charcoal Canister

    its an open vacuum leak sucking dirt into the engine. You have to plug it and adjust the carburetor or put a charcoal canister back in. Personally i would put the canister back.

    83 Chevy breaks 2in or 2 3/4in shoes

    there looking to see if you had heavy duty or standard duty brakes. Measuring the rears is an easy way to tell them apart. Just get both sets and return the one that doesn't fit

    GM paper or K&N hi- flow filter, Worth the cost in a stock truck ?

    I have used K&N on a lot of off road toys with no complaints. They are good filters. Pros buy it once lasts many years just clean it, oil it and good to go again, it also flows more air than paper . cons oil is a little messy, doesn't filter as good as paper, on cars with MAF sensors too much...

    How does the oil gauge function? Mine is pegged to the right

    if you run 12 volts to the sending unit nothing good will happen, dont do it lol. The sending unit acts as a variable ground for the gauge so puting 12 volts directly to it will fry it. Start at the junction block look for a dark blue wire that should be your oil sender wire. The gauge...

    Seatbelt, Ignition Warning Buzzer

    To the best of my recollection 77 doesn't have a key warning buzzer. The seat belt buzzer you will probably have to get a a pull apart.

    ‘77 C10 hp increase

    A cam swap will probably give you the best bang for the buck. something like Comp cams cl12-210-2 cam kit should be mild enough to work with your stock motor and give you some more hp.. A manifold and headers will help to. Anything more you should consider doing a complete motor.

    Sway Bar End Link Bushings

    have you tried using a piece of all thread to pull it through? assemble all thread with nut/big socket/bushing/sway bar/bigger socket/ nut Tighten the two nuts and it should pull it through. a little lube helps to.
