    350 vortec 5.7 lower intake leaking vacuum?? Help please

    It wasn't a bit funny at the time.. It was THE MOST unreliable vehicle I ever owned. But now I get a chuckle every time I tell the story. All that trouble because of a bad formulated antifreeze????????? The only time I know the bolts were not replaced was the time I replaced the gaskets.. I...

    1986 gmc C2500 smog control deletion.

    We'll probably never know.. The OP posted the same question on the introduction forum the same day he posted here.. Hasn't been back since, probably wasn't satisfied or happy with our responses.

    350 vortec 5.7 lower intake leaking vacuum?? Help please

    Way back in June 2000, I bought a '99 Suburban with that same 5.7.. At the time of purchase, it had less than 20K miles on it.. I also purchased an extended warranty.. within 6 months, it developed a water leak at the rear of the engine. Warranty replaced the lower intake gaskets and all was...

    Small block to big block swap. What do i need to know?

    For starters (no pun intended), flex plate, accessory mounting brackets, four core (or equivalent) radiator... An adjustment to your fuel budget is also required.

    Cargo and Dome not working

    Be organized in your troubleshooting.. Guessing will just send you down rabbit holes. Electricity is invisible, you can't depend on your eyes to see it.. You MUST use test instruments. Something as simple as a test light or as complex as a voltmeter will allow you to "see" electricity. Get one...

    78 Silverado Big Ten Grounding Issues???

    That's a normal situation when the negative cable isn't connected. But there isn't a drain unless something is turned on or malfunctioning. For example, the same situation exists with the dome light circuit.. voltage is always present on both "sides" the bulb, but it doesn't come on until the...

    Edelbrock electric choke question.

    In colder climates, it's not unusual for the choke to need seasonal adjustments. All electric choles are adjustable, no matter the brand.. First, with engine running, check for voltage at the choke terminal, should be 12 volts. If the choke has 2 terminals, one of them must be grounded. If no...

    Headlight issues

    Those orange wires have nothing to do with the headlights.. One of those orange wires comes from the fuse box, providing power for tail lights, and dome/courtesy lights. The other one goes to the courtesy lights.. The orange wires should have voltage on them all the time, not switched. The power...

    Cargo and Dome not working

    They all share the same fuse, but none of them are grounded directly.. The white wire provides a ground path to the door switches and headlight switch, which completes the ground when switched.

    Cargo and Dome not working

    Visual inspection of a fuse does not always determine if it's good.. Either test it installed using a test light/DVM to probe each end of it for voltage. An alternate test involves removing it and checking it for continuity. That orange wire starts at the fuse box and "meanders" all over the...

    1986 gmc C2500 smog control deletion.

    You can't just remove smog items and expect everything to be OK.. The reason you have a check engine light is because the computer isn't receiving feedback signals from whatever you removed.. The ALDL is located at the bottom of the dash near the steering column..

    Radiator Leaking

    So the hose was leaking because of loose clamp, not the radiator??

    Priming a New Water Pump?

    Does this mean you have a serpentine belt system?? It's normal to assume the new items are not the source, but do not arbitrarily rule them out. Unless the idler pulley was replaced in an attempt to cure the noise, it should not be ruled out... If the noise is more prevalent when cold, then...

    Priming a New Water Pump?

    First, no, the water pump does not ever need to be primed. Stop guessing at the problem. That's the last thing you want to do.. Here's a list of possible sources for the noise... Alternator, P/S pump, water pump, AC compressor if equipped, A.I.R. pump if equipped, and idler pulley if equipped...

    starter rebuilding - advice needed

    In 1966 when I first started out as a mechanic's helper, we rebuilt everything -- starters, alternators, generators, and yes, we even relined brake shoes.. We used a small lathe to turn down (refinish) the starter's commutator. That's the cylinder looking thing that's composed of multiple metal...

    Hot wire junction block

    That wire with the tape on it is actually a fusible link, a type of "slow-blow fuse".. If you follow it down behind that vacuum operated switch, you'll find it joins two wires together.. That fusible link has blown (melted) at some time in the past. it cannot be joined back together or repaired...

    Cab light question

    I guess the "politically correct" term would be nominal 12 volts.. A fully charged automotive battery registers 12.5 volts.. A properly working charging system will register between 13.8 and 14.3 volts.. Back in the daze, all bulbs were marked "12 volts".. These days, something got lost in the...

    No dash lights

    Reference the above posted wiring diagram..... The turn indicator dash bulbs share the same circuits with the front turn signal lights. The blue wire coming off the T/S switch splits off on the harness side and one "leg" goes to the right dash indicator light, while the other "leg" goes to the...

    No power at all

    [1] This is a classic symptom of a loose or bad connection on one of the battery cables. Check both ends of both cables for cleanliness and tightness. If your cables have those replaceable ends that clamp to the bare cable end, this could be your problem.. They are pure unadulterated JUNK.. Get...

    Cab light question

    You're making this hard on yourself, and that clueless counter person isn't helping the situation... Take one of the old bulbs that work with you to the parts place. Look closely at the base of the old bulb, a part number should be there. If not, simply match the bulb to what the clueless...
