Quadrajet idle solenoid
« on: June 22, 2012, 10:12:11 am »
I need help finding a idle solenoid for my quadrajet. It bumps up the idle when you turn on the A/C,.................. the previous owner removed it.

Thanks!

Don't know what year/model you're working on, but Napa, AutoZone, etc. sells them (e.g., here's one from AutoZone for an 84 C10, 350)...

http://www.autozone.com/autozone/parts/1984-Chevrolet-C10-1-2-ton-P-U-2WD/Idle-Stop-Solenoid/_/N-ik2xfZ9gsoj?filterByKeyWord=idle+solenoid&fromString=search

They should be commonly available.

It's difficult to know just how much you don't know until you know it.
In other words... if people learn by making mistakes, by now I should know just about everything!!!

Well, I got the NAPA part and it looked good, but its not the right one.   Bracket is wrong and terminal is on the wrong side. I could probably make it work, but I would have to drill out some spot welds and turn the "motor" 180 degrees, and make a new bracket.

The more I mess with it, I could just add a piece of metal to the linkage so the plunger has something to push against.

Pull the numbers off your carb to make sure you've got the carb thats supposed to be on your truck. Different production years had different ways of mounting components.

Yes, its the correct 1984 quadrajet.   I ended up using some .060 aluminum and making a "stop" for the solenoid plunger.  It works, I just need to check my rpms at idle and see how much it kicks up when the solenoid is activated.

Glad you found one, so sorry I hadn't ventured out to the shed yet... Still a little wobbly walking on uneven ground yet...

Checked my rpms today.  In park idle is just under 800, when I engage the A/C and the solenoid, it bumps it up to just over 1000 rpms.
