clips and bolts for various places

Took off the front bumper cover yesterday to straighten out the condenser fins. As usual, problems with the fastener hardware.

1. The radiator cover tray had two types of clips. Two were simple push clips (pry up the simple button to release) and those came out easily. No idea where they came from. Four were generic (ie, not OEM) 90467-06017, the kind with a Philips head center piece that should turn, then pry up. Also supposed to be able to push up from underneath. Nope and nope. The center pin did not extend below the outward clamp legs, and the stupid soft screwdriver slot stripped or wouldn't turn. Had to remove all four destructively (pry up the screw head with a tiny screw driver, grab it and the post with needle nose pliers and lift to release). I had put those on the last time the tray had to come off, when their predecessors disintegrated. On reassembly used some generic Dorman 961-075D 6.4 mm push clips from Advanced Auto. The outer part fit fine, but the push part had to be put in with a lot of force. I'm betting these don't come out easy now, let alone after cooking in the car for a couple of years. I really prefer the simple push pin clips without the screwdriver complication. Anybody know of one of that type that works well in this application?

2. The 3 clips holding the bumper cover to the radiator support, 52161C, were breaking apart. Tried Dorman 963-552D from Advanced Auto, which are Subaru bumper clips. Both are said to be 9mm. Unfortunately the Dorman clips would not go into the hole, they were a fraction of a millimeter too big. So I put the cruddy ones back in, but since they are not really clamped in there, they need to be replaced. The Dorman 963-125D looks more like the Toyota part, but there weren't any in the store. Also 9mm. Probably. Are 52161C clips 52161-16010, 52161-02020, or some other Toyota part number?

3. On the bottom of the bumper cover there are bolts with 10 mm heads, a rotating but retained washer, and threads that are very coarse. These go through the loop on the bumper cover into a white plastic retaining clip which is attached to the shield behind it. One bolt was missing, and one screw had a substantially narrower diameter. The skinny one had apparently been driven through both the shield and the white clip, but not in the part where it was supposed to go, just through the plastic flangs. That skinny bolt would not "bite" into the retaining clip, so the car is now two bolts down. What is the part number for this screw/bolt? This might be it, but in the picture it doesn't look as long as the screws on my car (2007):

90080-15091 - Fender Liner Screw 2000-2024 Toyota | Longo Toyota Parts

maybe it is this one, seems like a closer length:

90159-60215 - Bumper Cover Retainer Screw 1996-2023 Toyota | Longo Toyota Parts

Also what is the part number for those white retaining clips that goes with this screw? I'd like to replace the mangled one at some point. Maybe this?

I have one. That's where the crappy 90467-06017 clips came from. The clips look good, but somehow they don't work well. My guess is that they used a really low quality batch of plastic.

 

I use one of these:

Push Pin Pliers

works great, the tips are at just the right angle to slide under/pry up the central part.

 

I obtained some 90467-06017 from Clips and Fasteners

Screw Type Retainers Toyota Mazda

which were better quality than the (also) generic ones previously obtained. Bizarrely, these fit into the front 3 holes on the "tray" over the radiator perfectly, but they don't work on the back 3 holes. In the latter case the screw won't advance, it just goes round and round and never goes anywhere. The holes in the back (in the metal pieces under the tray) must be slightly smaller than the ones in front.

So, I used the Dorman 961-075D in the back. And a few weeks ago I had tested that they could be removed successfully and all 3 came out in one piece and were reinstalled. Today I needed to take the tray off again, and guess what, the Dorman's only come off nicely one time. This second time the "cap" on the center pin broke off two of them. The center pin on this fastener is very narrow, not a huge surprise that it breaks easily. To get them out the "washer" like part above the tray was pried up, and it too snapped off. At that point it was possible to force the remaining part down through the hole. When the tray was put back on new Dorman fasteners were used again, but the center pin was left a few mm up, which hopefully will make pulling them out less traumatic for that center pin. Maybe they can be used twice that way?

 

This sort of thing, 7mm and (have to measure spaces in tray) head diameter?

 

There is a bit of a trick to using the Dorman 961-075D - don't push the center pin in all the way. I found that if the pin was left about 1/4" out that the force needed to lift that pin out later out was much lower, so that none of the pins broke. Also since the top of the pin is sitting up in the air one can just use a flat bladed screwdriver or a trim tool to lift them up. In that "no quite in" position the clips are still very tight, they are not going to come out.

That said, the clips taken off the car were much less flexible than those from the same pack which had never been used. That is, the little legs that spread out on the bottom were quite stiff after sitting in the car for months. Both used and unused were at the same temperature too, as both had been sitting on the driveway near each other for half an hour or so. I think this may be a general problem for plastic clips, not just these Dornan's. It will not surprise me if, when removing these again in a year or so, the legs snap off instead of the pin breaking.
