I'm looking for a Diverter Valve for a 92 Camaro 5.0 V8. Sadly, all auto parts stores are discontinued
AC Delco part number: 17088105 or 214-116
I prefer new, but am willing to go used if the part isn't too old or worn. My smog guy said to just replace the grey sensor... Unfortunately, he didn't realize that it's one piece with 2 sensors (black and grey). Oh, well. Here's some pics of what it looks like. Please get back to me if you have one or know of a hidden utopia of them somewhere online! Thanks!! My Smog guy said just to replace the grey side... not possible. Need to replace entire part.
Thanks for looking out! I saw these on eBay before. They've been up for a while. I'm in no hurry so I refuse to spend that kind of money. There's also a few used ones on eBay. However, they are in terrible physical condition. I remember when this part was around $100 for a new ACDelco part at AutoZone. I'd be willing to pay no more than $150 to $200 for new.
I also noticed that the 1987 Buick Regal with the same 305 V8 uses what looks like the exact same diverter valve. I found them on eBay, however it says it's not compatible with the Camaro. Seriously, it looks 100% the same.
The solenoids pop right off. Find a good solenoid, carefully spread the plastic clips apart and remove the solenoid. New/used one just snaps back in. Pretty sure there's an O-ring seal between the solenoid and diverter body, you may want to replace it for peace of mind.
GM would have you replace the diverter valve as an assembly. I know the solenoids come off because I've got a diverter valve in storage missing one, and a pair I salvaged from a car with a broken diverter valve.
You should be able to test a used solenoid with a 12v power source. Connect positive to the terminal with the + mark, and - to the other terminal, it should click. I don't have time to test one at the moment, but I think the solenoid is normally closed. When it's powered, the solenoid valve should open. Probably can test it by blowing through the valve. You might also check the existing valve and make sure the passage isn't blocked. That is assuming the mechanic is consistent and trustworthy. There's probably about 6 pages of diverter valve detail, theory, and troubleshooting in the GM service manual. You might want to verify that the ECM is grounding the solenoid, and that the diverter valve is functioning aside from the solenoid before replacing parts, but your mechanic should have tried that before recommending replacing the valve.
Good advise Drew! I've been going to my smog guy for close to fifteen years now. Last time I tried to smog my car, it barely passed. My smog check is coming up in June and I want to make sure it's perfect before that happens, while I have money to spare. So I took it to him and he ran tests on everything emissions. He tested both solenoids on the diverter valve and told me to replace the gray one. He also said I need a new O2 sensor. That part is super cheap and extremely easy to replace. I'm one of those people that cares more about the car running perfectly than anything else. Especially with these older cars. You should see my other posts about how I upgraded the cooling radiator system. I keep saving up money to try to get the car painted and a new interior, but life keeps happening draining my funds. Finally graduated college and hopefully things will change...
