How does the AC compressor mount?

I think you reach the bolts through the openings in the pulley

That sounds like the PS pump to me.

AC compressor has 3 bolts securing it from the driver side. The back one is right behind the oil dipstick tube. You don’t have to remove the back bolt, jus loosen. The front 2 bolts mount the AC compressor to the fan bracket - these bolts need to be free from the threads in the fan bracket.

My project took a turn when I assessed the bearing in the fan bracket, it was a little scratchy. No play in the bearing. Oil visible on the back. List price locally is over $400!

DON'T buy locally or from dealer. Get the Aisin fan bracket, should run about a C-note. Good idea to change it out now as to do it later has you about 2/3rds the way to a TB job.

You guys are awesome! Looks like this won't deliver until next weekend...
The will be missing her truck!

Although I think I might be delayed on this as well.

This hose down by the oil cooler looks like it is starting to bulge.

Another one of those "might as well while you are in there":

If factory seals aren't leaking, I'd do not touch them. I've yet to see crank or cam seals leaking or even weeping, unless they've been replaced or "HIGH Mileage Oil (very damaging to seals)" used. If leak does develop over next 90K, it will be very minor. It can always be replaced next T-belt job.

The most common leak I find, is tensioner pulley bolt (No. 1 timing belt idler). Which goes into oil pump housing. Only because last T-belt job, threads were not sealed with sealant. I typically use Toyota FIPG 102 or 103 0il, but any oil rated thread sealant will work. Just don't use a permanent one like red loctite.

You'll for sure find pitting on the block under water pump gasket. Do not file on block as shown in thread. Use wire brush, green scratch pad, etc. and degreasers. Getting gasket mating surface and pits cleaned out. Then fill pits with FIPG 1282B, scrape flush to block, let cure before assemble.


BTW: The lower fan bracket bolt that goes through AC compressor, made easy.

Make sure to put the little cover spacer & gasket back on, after water pump installed and before fan bracket install.

I find this clip busted from previous service very often.

This picture from the quoted post shows very well how to remove the lower, front AC compressor mount bolt:

There are 3 bolts mounting the AC compressor, all accessed from the driver side of the compressor.
None of them are easy to access. The front 2 need to loosen until they are completely free of the threads in the fan bracket.
The rear mount bolt for the AC compressor is reached from above by reaching back behind the oil dipstick tube. I only loosened this bolt, I did not remove. That was enough to move the AC compressor so the fan bracket could come out.

AFAIK, you do not need to remove the oil filter for this project. But I am not finished yet either!

There's no need to loosen the rear bolt on the AC compressor. It's just busy work.

My pulley holder is still around and available, I've mailed it out to other mud members. I'm pretty sure the bolts taped into it are for the 100 pulley.

Pulled my Oil Cooler when I did my steering rack and replaced all the hoses and seals in the cooler. A couple of the hoses were soft from having oil leak on them and my Oil cooler was leaking slightly from a dried out seal.

That is good to know!
I would have tried to take you up on that, had I known!

100 series 4.7L are 65mm apart, 80 series 4.5L are 90mm apart. It looks like your tool has both.

Yes, I've used it for both. Plenty of room for more holes.

I can also bring it with me as I travel, next week I'm in chicago, San Antonio and Newark.

Just an FYI: All you’d be getting for that 100% markup by buying from Toyota dealer is their logo stamped on the part. Below is an Aisin fan bracket I got a few months ago for a 3vze (Toyota’s $hittiest engine ever produced). Note the “TOYOTA” etched out. This part is $345 with TOYOTA stamped next to AISIN, but is just $115 with TOYOTA scratched off. Same part, same OEM manufacturer. Buy wisely, friends…

$230.00 labor to scratch off Toyota DOES seem a little steep.

This is as far as I got yesterday - new thermostat in, new water pump on, and timing belt in place:

 

[PabloCruise]

Tensioner is NOT on yet.

This slowed me down quite a bit - I could not separate the thermostat housing from the front coolant bypass pipe:
