How important is the front bumper spoiler?

I can only find Amazon Canada link for this, aftermarket equiv I believe. I haven't purchased myself:

 

The spoiler is for aero....it may route air to the radiator (performance) and around the front tires and also the under carriage (fuel economy)

IMO 700 mile trip (highway), I don't it is necessary to replace before family member borrows the car.

But If they are going to travel in the hills and if the spoiler does direct air to the radiator, it could be prudent to replace first.

Me, I would replace with OEM because I do not like to drive damaged cars and the cost is what it is.
An overheated engine will ruin the trip.

I don't know the answers to your other two questions.

Good luck.

 

For future reference, the spoiler is $31.79 on Rock Auto. I usually check there first, because they tend to have the lowest prices.

 

I am in a similar situation in that I have half of the original part hanging on by one faster such that the free end is dragging next to the front driver-side tire. RockAuto is up to $40.79 for this TO1093124, but I don't know what fasteners I need to install it. I expect I'll need the full set, but the Toyota diagram doesn't provide part number that seem useful.

Can anyone provide any leads to the correct fasteners?
Tips for doing the installation (it looks pretty simple, but appearances can be deceiving)?

 

Not trying to be clever: dealership parts department can sort it out, and would guarantee fit if I’m not mistaken.

I’ve had it off, and it’s something like:

4 coarse thread screws (go into plastic blocks)

4 bolts (screw into weld-nuts)

One plastic push-in fastener, bit of an off-ball longer one, at centre.

The shield itself is prone to snag on concrete wheel stops: scrapes over them ok, then hooks/rips coming back off.

 

I bought a kit off Amazon to replace both fender liners and the front spoiler part 76851-47030. The part they sent said it would fit a 2010 and most of the holes line up with the old part but it doesn’t go against the bumper the same way. Is this the way the spoiler is on newer gen 3s? I can’t even figure out which side is up on the Amazon part.

 

There's two styles for that piece, and AFAIK only the one saying "front spoiler" is for North America. Not really sure. The alternate style may well work too. The "front spoiler" style is REALLY good at snagging on concrete wheel stops; the other might be better in that regard.



That screen grab is from a PDF excerpt from Repair Manual, first page of the oil change instruction. You can download that PDF from the oil change in link in my signature.

 

the Amazon one would stick down below the bumper creating a gap. Kind of sucks because I was expecting an aftermarket match and thought it was a good deal. Would rather have the oem one. Thank you for the screen grab. I can see which way is up now. I’ll see how it fits and decide whether to keep or get an oem.

 

Looking on Amayama, this page:

see this:


maybe Google those two 52618… part no’s, see what they look like. FWIW.

Ours I’ve glue repaired multiple times, just due to concrete wheel stop damage.

 

Did Toyota update the engine cover no 1? I gotta replace that. Mechanic pulled it off when it broke years ago.

 

Do you mean the main engine under panel? Not sure if they’ve updated, and original version is fine. Attached is some info on the panel, and its fasteners. See also oil change link in my signature, for some tips on preserving it, and its fasteners.

 

One of the joys of buying something through Amazon.
