question about cleaning throttle body

[juntjoo]

should I take off this lower part of the TB and clean inside? it's this lower half that the ISC goes into. and if I should, how best do I go about getting those philips head screws out? thanks

yes the isc goes in there i would get a vice and hold it then extract them kinda hit or miss to remove them soak with some blast maybe, and some heat why are you removing them?

The best way to remove them is an impact driver (hand tool).

I wouldn't really recommend taking the FIAV off unless it's leaking. There's not much that really needs to be cleaned in there.

I have a cordless 3/8 impact gun and used the tip off my impact driver (3/8 air gun will work also). Worked like a charm, didn't even have to use blast. Its a trick I learned replacing rotors that have those damned keeper screws in them. You don't even need a vice.

I was just wondering if I should clean in there since I took the TB out to clean. I guess I won't worry about it then.

I got mine out with just a screwdriver and some muscle. Might as well clean it up while you have it out.

You must've gotten lucky and/or they had been removed before and not tightened down very well. Most of those screws are in there good and will strip even when using a power tool.

You did get lucky. Most of the time you will get maybe one or two loose with a screwdriver, get a couple more by clamping the screw head with needle nose vise grips, and then two or three you have to just drill the head off and then remove the threads after you have it apart.

If your going to take it apart you might as well figure that you will have to replace them. Last time I did I used allen head screws so it would be easier next time.

I never had had to remove mine so i just let them be, unless you need to get the the fiav i would leave it alone.

Everybody always trashes those screws. That is because they are metric, you need to get a "JIC" screwdriver from someplace like jensentools.com. That is a different variation to a philips screwdriver. I use these all of the time at work on electronic equipment and it makes all the difference.

Leave it alone.
