'97 Fan Clutch

[dgerst]

So I read about the R/C diff oil for the fan clutch and, since my A/C wasn't as cold as I'd like at idle, I ordered a bottle of 10,000. This morning I removed the clutch, took it apart, and put it in a 195F oven while I ran a few errands. An hour or so later I wipied it down, filled it with 50ML of the new oil, and re-installed it. After starting it I heard that whoosh I haven't heard since last starting my 22R-powered motorhome. The fan is moving way more air after warm-up and the A/C is MUCH colder at idle.
I probably could have used 20K oil as it's 112F today here in southern Kansas but we don't get many days that hot. OBD reader is showing 203-208 coolant temp at idle with A/C on. I'd recommend this to anyone who hasn't done it. It's a cheap, easy improvement.

I was always impressed with my old '88 Trooper's build quality when I worked on it. The LX even more so. I don't think I've ever owned anything built like this. It's a tank.

Anyway thanks for the fantastic forum. folks are saving tons of time and money because of it.

I'm not sure what brand my clutch is so I've attached a photo. Maybe someone can ID it. It came apart with 4 T-20 Torx screws.

Thanls again!

I hope you realize you needed to put two tubes of Mr. T fluid in the clutch. If two Mr. T tubes equal 50 ml then, never mind.

So does the clutch have to be heated up prior to swapping the oil; hence the oven bit.

The oven bit just speeds up the oil draining process. I'll never know just how much, I'm not allowed to touch the Pyrex when I drain mine...

No. I separated both pieces, let them drain for approx. 30 minutes, placed new 35 mil 20k bottle in a heated pyrex cup of water, then poured it in. Total time for me was about an hour start to finish. FYI my garage temps were about 100 degrees and probably helped with the drain.

I hope your lady didn't see the way you used her baking pan.

Why, it's just silicone, she probably rubs it on her face and ingests some everyday, plus it's now a nonstick pan!

I know,,,, logic doesn't work in this type of deal!

She was remarkably tolerant of my kitchen takeover. I clearly don't deserve her. Her patience will be re-tested when the 20K comes in and I change it out again

Since I had a bottle of 10K sitting in the garage already, I got motivated and did a little late night wrenching.

Question: How much oil are you guys able to drain out? I heated up the assembly with a heat gun but still did not get much out. I said to hell with it and put in 1.5oz/ 45ml and bolted it back together. Real test will come tomorrow when it's scorching again. I assume the oil is suppossed to drain down into those three holes; obviously I don't know Jack about fan clutches.

Post #36 of the thread below has a good description of draining the clutch.

Who sells the fluid?

Thanks, jt

CDan sells the Toyota fluid up to 10K cst.

For heavy fluid, try your local hobby shop. Team Associated and Mugen are good brands, but there are many out there. There are also several online sources for the fluild which can be found in some of the recent fan clutch threads.

Hobby shops. Found mine on eBay.

I have a load of 30,000 CST fluid that someone bought accidentally. Let me know if anyone needs any!!

You might as well load the fan clutch full of Gorilla Glue...!

Yeah, no kidding!!!

 

[Tools R Us]

So, Gorilla Glue works in fan clutches, I would guess that silicone would be more efficient?

If your desperate to be rid of it, I will take it. But have ~250ml of 30K, so someone else may have more immediate use for it?

 

[Atoyot1031]

I'm running 30k, and it's finally right...

 

[Eicca]

Whatever's in the clutch I just put in must be something close to Gorilla Glue. It almost never turns off.

Hey, $70 from Napa, could be worse!

What's wrong with the 30k fluid? I thought it was the recommended fluid for the late blue hub Aisin clutch?
