IAC cleaning revisited
Posted 19 April 2005 - 09:49 AM
A more recent thread seems to imply that you can just remove the electrical part (held by the vertical screws) to get to the part you need to clean.
Could those that have cleaned their IAC valve give their opinion on this. I would prefer not to remove the entire body (seems a little involved) if not necessary.

I don't see a way to clean this item by only removing the electrical portion with the vertical machine screws from the top.
I wish I had a photo of this thing...
The body of the IAC has a flapper inside of it which turns to open/close the port (I am sure you know this). This flapper is connected to a shaft which passes through a bearing and has a magnet at the end. This magnet is then surrounded by the electrical cap which causes it to open/close.
The part you want to clean is the body, which is separated from the magnet and electrical part by the bearing. I suppose it is physically possible to just remove the hoses from the body and spray some cleaner in there (which would then go into the engine - bang on startup ?), but I don't know if this is a good idea.
I suggest removing the body/electrical together (take out the horizontal bolts first) and then clean the body. Whether you even need to take off the electrical "cap"...I don't know. I did, but there wasn't really anything in there.
There is a gasket between the IAC and the engine, so you might want to pick that up before tearing this thing apart.
Hope this helps.

Nice to see your response, hklaine. Did you notice a difference in running after the cleaning?
Aloha all, good luck.

Let me hitch-hike on this thread. My IAC has slots in the electrical cover where the phillips screws go in for some kind of adjustment. What's this all about?
I think this adjustment was made at the factory and must no be tampered with.

Forgot to add, I'm pretty sure it controls how much the shutter oscillating thingy inside opens. This is why it is a good reason to take the connector off when cleaning. I found a lot of gunk was at the point where the shutter stopped, I think this is where a lot of the sticking occurs. By taking the connector off you can get all this gunk off.

So Frag, how did it go? Or are you still out there in the dark spraying cleaner through that thing?
He he... no I have'nt found the time to do it yet. But soon...
