Used the Thoroflush they sell.

 

I got a the GM standard duty clutch from autozone and paired it with a p38 fan. During extended city driving in 50* weather, temps were the same...195 to 203.

When I got home I let it idle till it hit 203, then had my wife shut it off while I stood at the fan with the hood open. When the engine stopped the fan kept spinning for a good 3 sec. Once it stopped I spun it by hand and it would go full revolutions.

Did I get a bad new clutch?

 

Yes. Should feel like peanut butter inside, not penetrating oil.

 

Wow, ok.

How common is it to get a brand new bunk clutch?

 

Depends on how they store them. Should be stored vertical, so fluid can't seep out a seal. BUT, in all fairness, be sure that you have serpantine belt route by the book. Quality control seems like it is part of inventory control. Bonus pay for more units shipped, production targets exceeded. The fiscal incentive to fib may have originated with sales weasels, but has been admired and adapted by many other managers.

 

It was in the box face down, but in a plastic bag and no sign anything leaked out.

Im 99% sure my belt routing is correct. Even if it wasnt, Im guessing the fan clutch shouldnt freewheel like that when the engine stops at 203*.

Im gonna exchange it for the HD version today and see what happens.

 

Would not advise the HD. It stays "engaged" much longer and is a drag on MPG, more fan roar. When I did it, I think the with AC HD version was also larger diameter (like 7 inch instead of six inch).

 

So, if you do a search for a 2001 Range Rover, Autozone stocks a clutch for it.

What sucks is, I already opened the holes of the fan up for the GM. Im thinking that may not be a deal killer, since the inner fan ring is "hub centric".

Interesting Update:

The Autozone Torqflo clutch is listed as standard duty.

If you do the 2001 p38 search at Oreilly, it gives you a Hayden and a Murray brand, both listed as heavy duty.

 

I bought the one for a 2000 Chevy Express, 4.3 liter, without AC.

 

Good news.

The Torqflo 922302: Autozone.com is a $72 direct replacment for the OEM clutch (mine did not come with bolts or lock washers...8mmx1.25). The inner "hub" fits perfectly in the p38 fan ring. It is way beefier than the standard duty GM. I would imagine it is of similar size to the HD GM. I dont know what was up with the standard GM clutch I bought, but it was as bad or worse than the old stock clutch.

50* weather again. After a 10 min idle I went for a short drive to get gas, then back home and let it idle for another 10 min or so. Temps topped at 195 and would go down to 190 under short acceleration or revving in neutral in the driveway. The 95* Tuesday we're getting will be a great test, but I think the cooling system is golden.

Ive got a new upstream sensor coming in tomorrow. The current one is totally shot and runs in open loop all the time. I think that should get rid of the occasional shaky engine activity and give a better idea of how the engine runs coated with Irontite.
