    R4 to Sanden whith stock ac lines(for serpantine)

    I think my 1989 Suburban is going to need this upgrade as well - will the listed part numbers work with the 454 or are they different between SBC and BBC engines?

    Rear camera installation

    I got one of the folks here at work to order me the Wolfbox setup that has the in-mirror front facing camera and a small backup camera. I use it in my 1989 Suburban that has the ambulance-style doors with just 2 small square windows you can't see much out of. I mounted the backup camera on a...

    Suburban Rear Heat & AC removal/installation/compatability

    I like the idea - and I just happen to have a whole box of various 12V PC fans sitting around. OF course we're just now getting to where the A/C isn't needed as much, but its worth fiddling with....

    Suburban Rear Heat & AC removal/installation/compatability

    I'm not overly picky on color - my interior is blue but they make pretty decent plastic sprays now that work pretty well and my interor isn't show-car pristine anyway (no headliner cloth for example - just the carboard backer which I may also just paint blue and call it done). My rear AC fan...

    Suburban Rear Heat & AC removal/installation/compatability

    Is the fan housing and mounting in good condition?? If so I'd be very interested since mine "works" but the fan is held on with zip-ties and prayers....all the original plastic has become brittle and cracked apart.

    Aux battery for audio

    My impression was that he wants to run dual batteries not because the main battery/alternator is inadequate, but rather for the ability to run the audio for extended time periods without leaving the truck running or risking depleting the main battery to where engine start fails. I can see the...

    Rear brake bleeding struggles

    Appreciate the detailed info - I'm hoping it will be a while before I have to even think about this, but having some idea of how it goes (and that video from Chevrolet) makes it less frightening.....

    High Oil Pressure and Leaking After Oil Change

    Certainly sounds like a blockage somewhere in the system to me. Do you have an external oil cooler with lines going up to the small oil radiator in front of the main radiator (I have one on my Suburban but don't know which models did or did not include this)? If so, thats the 1st place I'd...

    Rear brake bleeding struggles

    Don't you have to remove something from inside the center section to enable the axle shaft to slide out???

    Rear brake bleeding struggles

    Hopefully you have the type of rear end that lets the drums just come off when you take the wheel off. I have the full float 14 bolt and removing the drums will involve pulling the axle shaft out of the center section. Needless to say I'm not at all looking forward to THAT when the time comes.....

    Fix Slamming Doors - Striker Door Latch Repair

    My friend Dave did all 4 doors on my Suburban that way one day - the 1st one he actually went through the process of removing the striker, heating the PEX slightly to get it to slide on and then reassemble. After 2-3 hours of that he said to <---> with it and just did the lenghtwise cut and...

    Barn Door Alignment?

    They make plastic panel grommets for these? Mine never had any since I've owned the truck and I always worry about water incursion/rust as a result? I didn't know they existed....

    Testing the wiring and gauge for 3 wire sensor

    It may not be that simple. If you have a +5 reference, a signal out and ground - that (to me) implies a digital output which isn't going to be a nice simple 0v=0PSI; +5v=100PSI type of thing. My guess is the sensor is sending out pulses at a variable frequency and the Holley ECU counts the...

    1999 454 carb swap. best street carb, 600? 650? 750? CFM

    Nice clear explaination - makes sense too. Based on that, I'm assuming that a TBI (which is still technically electronically controlled so would still in my mind be an EFI system) would have the same drawback as a carb in that its a wet manifold setup? Whereas a newer style injection with an...

    Spark plug foul up

    Question on this: Does the O2 sensor generate the voltage (using a thermocouple-type device) or does the ECU provide a specific voltage to the wire going to the O2 sensor (voltage changes based on resistance inside the sensor)? Doesn't change the way the voltage is monitored, just wondering...

    Daughters ‘87 needs to ride smooth.

    The tires also wear along the center line faster when inflated to max PSI on an empty bed. The back tires that were on my former F250 were like that - the guy had kept them at the or near the sidewall rating which would have been fine when carrying a load, but way too much for the empty bed...

    Rear camera installation

    I am not sure that wiring will be under the dash since nothing in the cab actually depends on it - my understanding is there is constant +12 going to the switch on the transmission (which closes when you move the selector to "R") and then from there it goes right to the reversing lamps. The...

    Help with diagnosis and repair

    Weirder and weirder..... I'd almost bet you have some kind of small leak that is allowing exhaust into the coolant. It would have to be happening at a location where the exhaust pressure is higher than the coolant pressure because otherwise you would be seeing steam in the exhaust. I'd...

    Help with diagnosis and repair

    What does your dipstick look like when you pull it? Could be cross-contaminating coolant and oil, which could come from either lower intake or head gasket... If you pull the oil stick and have something that looks like brown mud, or notice any kind of whitish foamy looking stuff on the inside...

    Repeated stalling

    I will do that! I was not aware you could do that without turning off the key first. That may yield a previously hidden data point.

    Very fast idle on start

    If giving a tap on the pedal slows it down, could be something simple like a linkage binding. I'd start by verifying everything moves freely and smoothly.

    Filling small holes without welding

    I had to do something similar with a small section of the floor area of an MGB up under the throttle pedal - a very difficult spot to access for cutting out and replacing (and above where the replacement floor pans went up to) - pinholed but not completely gone. I opted to work across the...

    Repeated stalling

    Here is a relevant question where I occasionally experience a similar but not always identical issue. When it stalls, can you immediately restart without turning the key back to the OFF position? In my case it will give no fuel or spark until the key is rolled back to fully OFF, then it will...

    TBI timing help…

    I'm still trying to get my mind around the injectors continuing to trigger once the engine stops. Since the injector pulse comes from the distributor pickup similar to the ignition coil trigger, if the distributor isn't turning they injectors in no way should be firing at all. If something is...

    TBI timing help…

    Hold the phone! Injectors were running after the engine stalled? As in trickling fuel, or full spray? That could be a symptom of a different problem. My (probably incomplete - others feel free to fill in what I miss) comprehension of how the injectors work is the computer gets a pulse from...
