Hi all - happy mother days to all mothers on this forum :)!

question I sill do not have sufficient cooling in my LX450 during summer days, my brother who is a pro in AC conditioning noticed that radiator fan is not seeded correctly as you can see on the image unis TRD provided spacer, he said that fan MUST sticks out 1/2 in relation to the shroud or it will not pull the air well enough to cool. I see that Wits'end selling orange TRD fan clutch that suppose to deal with this problem of my. any comments?

TY all.

Best approach is to use the orange hub clutch from Wits end and your original fan that was on the rig. Positions the fan correctly fore and aft and is modded with the heavy fluid.

The best fan to use is the fan that came with the truck. However it will contact the SC pulley without the spacer and contact the radiator with the spacer.

So I came up with modifying the orange clutch which is slightly taller than the Blue clutch to fit our water pumps.

Using this clutch allows you to use the 1FZ fan without the spacer and it doesn't contact the pulleys.

I further modify the clutch to perform better by pulling more air at all speeds.

Included with the clutch is 4 factory water pump studs in case you no longer have them from replacing them with the longer TRD studs.

this thread should help you understand what is going on.

ya the price is a bit steep $400 for the clutch fan.

I just spaced the stock fan off of a Blue modded fan clutch. I used 1/4" washers (IIRC) to space the fan away from the clutch to get just enough clearance between the superchager drive belt and edge of fan.
Cost about 60 cents...

Took some pictures of different spacer setups to use the stock fan. The first time I saw this done was Kyle in Payson, have put lots of miles on them, trail and road, but motor mounts, shroud, etc, are important.

First an Eaton, removed the studs, put flange nuts on backwards and screwed them back in. The nuts are ~.235" so that is the spacing. The fan is spaced out past the centering nubs, but is easy to center it by eye.

Without a base spacer and the size of the Eaton, needed some room to get the belt past the main pulley, chopped it in the lathe.

Close, like scary, but works fine.
