Hi guys,
my T4R first gen 22Re's making noises from the fan, after a quick inspection I noticed it wiggles.

Do you know what the problem is? What did it cause it? How can I solve it?

Thank you and have a good day.

 

Bearings in the fan clutch FUBAR. You need new fan clutch right away.

Don't run it unless you want to buy a new radiator too.

Aisin brand fan clutch is best.

 

Yes, Aisin fan clutch aka liquid coupling. When I got mine there were lots of choices/sources online. New one shud last you another 30 years or so.

 

Rock Auto has the Aisin one. I recently bought and installed one.

 

Thank you guys!
I'm going to order an Aisin one.
Do you recommend me another preventive replacement when I change the the fun clutch? The water pump for example?
This 4Runner has 125000 miles on the clock.

 

Hi guys!
An update:
The water pump has 4 struds, to place the pump pulley first and the fluid coupling (fan clutch) after that.
It looks like the one that wiggles's the water pump assembly pin (I don't know it's name). Please see photo attached, inside red box.

 

Hi guys!
It was a long wait. I got all the parts I needed and I'm replacing the water pump and the fluid coupling (fan clutch) right now.
I took off the old water pump, it has a bad bearing, and I removing the old head gasket, but it's not easy, took me 1 hour to clean a few inches using a rag and my fingernails, so my question's about that, how do you remove it and clean the surface for the new gasket?
Thanks!

 

Nice!

Not the head gasket. You mean the water pump gasket, right?

WD-40 or brake fluid maybe to soften the rubber gasket?
And I like to use bamboo or wooden ladle with flat-straight edge to scrape things off cookware and metal surfaces I don't want to scratch.

 

Hi Ray!
Sorry, I meant water pump gasket.
I was the last 8 hours cleaning the water pump gasket. True story. I tried with my fingernails first, WD40 and a plastic scrapper after that, and gasket cleaner and a metal scrapper later.
The problem is, as you know, the surface to clean's in vertical position and there's not a lot of room to work. Because of that I removed the radiator, more comfortable to put my hands around there, I hope I can finish it tomorrow.
I don't know if scotch brite pads are good to use, some people say it's a NO NO, other people say it's not a problem. I don't know.

 

Nice job! Feels good to do things yourself, huh?
Scotchbrite should be OK to use to remove residual adhesive/sealant/gum. Better than a metal scraper.

(And I like the Toyota oil filter; you only have to keep one oil filter cap wrench that you know will always fit.)

While you have the radiator out, I suggest:
1) Rinsing radiator and engine backward (from bottom to top) to flush out loose stuff. (Follow with good flushing solution once re-assembled.)
2) Running 2 to 4 pieces of 12AWG wires along with the alternator / headlight harness running across the top of radiator. Long enough to reach from fuse block to headlights plus a couple more feet, for future headlight and/or horn wiring upgrade. You can always solder extensions later but save on the work of having to run wires later.

 

Hi guys,
I wanted to update this thread.
The noises were coming from the water pump, I replace it and I did the same with the belts. Everything looks good now.
I had some complicatios, I broke a wp bolt, but luckly I could remove it with something similar to the vampliers, in the first attemp with that tool.

Thank you @millball, @RAD4Runner and @Melrose 4R
