IAC valves for gm engines.

Post by Big Block Power » Sun Oct 16, 2016 5:59 pm

My boat kept wanting to stall coming off plane and when going to dock and started hard. I had a spare iac valve from one of my previous boats. I keep a spare. They fail to often. It seems like most of the gm engines use the same valve. I didn't pay $170 for it I paid about $12 for it. If you look up AC147 iac valve they pop up. My last one lasted over two years and worked great till I sold the boat and I'm sure it's still working. I figured was worth a try or else I would have bought one from our gm dealership. They are much cheaper than a Marine one. They do make a Ford style valve also that fail on a regular basis also. I don't know the part number for that. Installed it today in 5 minutes worked perfectly.

Looks like these idle air control valves are around $50 at the super-discount places, so a new one for $12 is a steal.

Yea that's why I bought 2 of them.I thought they have to be junk and cheap enough to try. When you compare them they look identical. So I tried it and never had to replace it again. So what the Heck. Normally you get what you pay for.
