Since I am running my 80 DD now I have been testing all my new cooling mods big time. I am not sure what the running temps are from the AC but my water temps usually run 186-191 when it's not over 100 outside. When its over 110 and I am sitting in traffic etc it has been getting up to 204-206 which is fine but I do notice a drop in the effectiveness of the ac and increased vent air temp. All of this is with the thicker fluid you put in Kevin and new radiator/thermastat and JDM pusher fan running. What is nice with the pusher fan wired into the pressure switch is that when I run into a store for something the water temps are lower when I come out then when I went in and the ac blows nice and cold on start up, which I ever had before the pusher fan install.
 
I'm still waiting to put in new fluid, but mine just plain out isn't even close to cold. Pusher fan, professional recharge and pressure check from trusted source. Evap looks and feels perfectly unclogged. Granted I have the uber-rare green color, but it is downright embarrassing how hot it remains/how cold the AC ain't.

What torx tools are needed again?
 
Scott...When you replace the fluid go with 30k you will like it.

I haven't put 30K in anything.:eek: The fluid depends on the clutch, the earlier clutches respond better to thicker fluid. My early type blue hub is hard on belts with 10K fluid. The later blue hubs take much thicker fluid to get the same drive. Rob's with 20K feels like mine.

IIRC we did yours early in the learning curve, new blue hub with 7-8K. With what is now known, that's too wimpy for AZ.:hillbilly:

What clutch?

Strange question but as I spend a significant amount of winter time (too bad not in the summer) in CO/WY has anyone reported TOO MUCH cooling?

Have you noticed any power reduction with 30k?

They are thermostat controlled, so no issue with too much cooling, it turns off. I haven't noticed any power or gas mileage difference, they come on when needed and then pretty much freewheel.
 
I did my dad's with 30k. I drained out the stock fluid but didn't allow it to drain as much as we did with mine so I think it mixing with the stock 3k makes it closer to my 20k It has worked great on his and both fan clutches were purchased at the same time.

I just used a #3 phillips in a impacted screw driver.

Good deal, watch the belts, in my experience they are the best indicator of when you have gone too far. Especially when in low range and it's been idling for awhile then stab the gas, the rpms come up quickly and the belts complain.

Blue, changed it in either 2003 | 2004 when I PM'd the HG. Don't have a part # for you though. Would that indicate the newer clutch I assume?

Right, but in any coupling like this clutch there should be some measurable increase in rotations given any given temperature against a stock clutch as a baseline, no? Regardless, I guess I'm hearing that it is negligible to operation (good thing).

I would guess late type, the for sure way to tell is the mount that holds the thermostat spring. On the early style it's part of the casting, the later type has a sheet metal stamping.

Yes there is some drag, but IMHO it's minor, well worth it for the result gained.
 
First the old, then new and the difference in shearing area.

We put 20K in Rob's blue hub today. Sounds/feels good, will see how it preforms.

Unboosted, my a/c was struggling to keep it below 80 at an idle on hot days:crybaby:

With the pusher fan it was 65 to 70

With 30k in the clutch it's been ~60 so far.:bounce::bounce2::cool:

Do you have 20K or 30K in it? I didn't want to question Kevin earlier because I thought he mixed it for you. (I don't see 20K pic in the 1st post.)

Is the ~60F temperature when at idle or driving on freeway? What was the ambient temperature? I am trying to decide if I should switch over to 30K.

I found the answers. Posting for future reference.
