What is the model of your vehicle?

Assuming it is for an LS400, all the model years appear to have the same bracket. I'm going off memory, but tomorrow I can give a better step-by-step from a service manual. (Just reach back out if that's necessary)

1. Remove fan clutch and radiator fan: four 12mm nuts hold the fan clutch onto the pulley. Unless you have a tool to hold the pulley, the best way to remove these nuts is with two wrenches- one you'll use to hold the pulley still (put it on a nut and hold pressure as if tightening it) and the other will be used to break loose another nut. Lightly seat the nut back down and rinse/repeat until the nuts are loose. Four 10mm bolts hold on the fan shroud, and after the fan is loose, you'll pull it out with the shroud. Take care not to damage the radiator fins.

2. Remove idler pulley and tensioner. (I believe these are 12mm bolts. You shouldn't need to take the tensioner pulley off the tensioner bracket).

3. Remove timing belt covers. (10mm bolts, as well as a 22mm bolt on crankshaft pulley). If you have a good impact gun, using it to take loose the crankshaft pulley will make your life easier. After the crankshaft pulley bolt is removed, use a universal puller to remove the pulley. You'll use M8x1.25 bolts to thread into the crank pulley in three locations. (Example puller below)Screenshot_2025-01-14-21-42-01-34_40deb401b9ffe8e1df2f1cc5ba480b12.thumb.jpg.48937ea26c7877f0a1adbdc2b7a99195.jpg

 

4. Remove all engine accessories bolted to the radiator fan bracket: There will be two bolts (I believe 14mm) coming in from the driver's side of the engine attaching the A/C compressor directly to the fan bracket. Check to verify the alternator and power steering do not attach to the bracket on your year model. It is advisable to loosen (but not remove) the bolts on the rear of the A/C compressor to allow a little more room removing and installing the fan bracket.

5. Remove the bolts securing your fan bracket to the engine block, and pry gently on the bracket to break it loose. Checking your new part for all mounting holes will help with finding any difficult to spot fasteners.

6. If budget allows, I'd recommend doing your water pump/timing belt while in there. You now have everything out of the way, and it's a lot less labor to do them now vs later if/when they need it.

Installation is the opposite of removal, and if needed, I can source torque specs tomorrow. (Again, just post here if those are needed.)
