    OK, this is a really dumb question. I'm sure the answer is somewhere in the forum if only I knew the name of this thing.

    Under the hood, there are black plastic fastreners that casually look like phillips head screws. If I pop up the center, they release.

    1) What are these called?

    2) What is the proper way to remove them? I am concerned that repeated removal using my carefull but unsatsifyingly clumbsy method will eventually break them.

    Clearley this is a fastener designed for assembly.

    I've heard those called by several names, not all them repeatable in a family forum. The name 'pop fastener' or 'plastic rivets' sounds more formal than 'those little plastic thingies', but most parts departments should know what you're talking about. They're designed for quick and cheap assembly, not repeated removal, and buying extra is a good idea because you're bound to wreck a few, or lose them as they go flying over your shoulder when you finally get them loose. Generally, the idea is to turn the phillips head part about 90 degrees - they are not threaded, so no point 'unscrewing' them - and then pop the centre part up. Then the whole thing should pull straight up and out. Once you've got one of the little buggers in hand, you can see better how they work.

    Easiest way to remove them is to push from underneath, you may have to turn them a bit with a phillips. Installation is the reverse, bring center pin up, insert, then push from top to reinsert. I think there is one that you cannot reach from underneath. There are reasonable substitutes in the Hardware store. Toyota charges $3.00 for each one. :bounce:

    I call them "f***ing plastic fasteners", usually followed by "g*dd**ned pieces of sh*t".

    That, of course, is technical terminology. Others may use something less formal.

    I find a paint can opener like this:

    very hand for the ones where you need to pull up the cap. Coupled with occasional help from a small flat bladed screwdriver.

    Just picked some up from Lowes, in the hardware aisle.- They have some "Automotive" fastener drawers.
    Small bags of two, for $1.04.
