Sure hope, if you plan on doing this again, you used some Anti-Seize on
the screws when you replaced them!

Aluminum oxide is juat as bad or worse than Iron oxide!

Let me give you hint...it is okay on some projects to use cheap, disposable
tools.

But if you ever ruin a critical component by using a cheap, poorly made
tool, you
will not soon forget it.

Cheap screwdrivers can ruin screw slots. Cheap wrenches can ruin bolt heads,
or even crack and ruin your knuckles.

Some Harbor Freight things are okayfor some purposes, but high quality they
are not.

I was about to say the same thing.
I bought a bench vice there for removing ball joints, and an air gun
for occasional use (axle nut, lug nuts), but the pry bars I purchased
were useless due to flex, and my hand tools are alll purchased
elsewhere. SK, Craftsman, Proto. Fine quality tools are really a joy
to use. Cheap stuff is a perennial frustration, although, occasional
cheap stuff can be helpful, like the vice when I just needed something
to grab the control arm. The pry bar I found at NAPA is superb and
suitable for a variety of uses beyond the initial purchase function
(LH axle) - for example makes changing and tensioning belts easy.
Those Harbor Freight pry bars really were completely useless whereas
the NAPA 18' pry bar is good quality steel, solid, dependable, a world
apart.

Oh, that's a good idea. I just didn't tighten the nuts very
tightly.

I was actually hoping to find some hex nut bolts to replace them...
anyone have any idea what thread those phillips screws would be?

I have to go back in there eventually - there are two coolant hoses
going to the throttle body that I'd missed when changing out all the
coolant hoses.

Thanks for the reminder. Yeah I have some good Craftsman screwdrivers
(wedding gift from my uncle). Was planning on getting a socket wrench
set for a brother-in-law, but now I'll look at the quality more
closely.
