I installed a few things at once (the new 4J/1G Thermostat, a Fan-shroud mod, and a New HD fan clutch & 11-bladed fan), since I'd have the hoses out of the way and things pulled.

The prep, tools, and parts:
Image

Pulled the turbo-box and some of the hoses to open up the space:
Image

Got the old OEM Thermostat housing ALMOST ready to be pulled:
Image

Pulled the rest of the hoses, and the OEM Thermostat housing (nice view of the open spot):
Image

Image

Cleaned the old Thermostat gasket gunk and bolted on the new 4J/1G Thermostat assembly:
Image

Started the Fan-Shoud Mod by using my Dremel tool to cut the Fan Shoud while it was still bolted in (at mid-point on each side):
Image

Image

Pulled both pieces of the Fan Shroud out, brought them inside, bolted on some window latches (kind of like these: http://www.hardwarestore.com/brass-window-latch-and-keeper-615708.aspx), and connected the Fan Shroud pieces:
Image

Image

Image

Image

Pulled the old OEM fan & fan-clutch and installed the lower section of the Fan Shroud mod:
Image

Image

Image

Put together the new 11-bladed fan with the Hayden HD fan clutch, and installed that dynamic duo:
Image

Bolted-on and latched-together the upper Fan Shroud over the new duo:
Image

Image

Image

Finished the Thermostat install, put all the hoses back together, and buttoned it all up!:
Image

Image

I filled my KJ back up with coolant, refrigerant, and tested everything. Bled out any remaining air, topped it off, and test-drove the beast.

Everything ran better.

Thank you again Jeff & team for such a beautiful and perfectly designed thermostat.

I towed my 19 foot Travel Trailer (4k lbs) to the mountains and had no problems with over heating or power!
I LOVE MY RIG!

Thanks for the pictures. I'm doing all that this weekend along with the Weeks kit.

Awesome work and pictures, why did you cut the fan shroud? Do you run with he MAF plugged in?

Thanks y'all.

Silver bullet, I wanted to modify the fan shroud for ease of future access to that area. There have been posts on Lostjeeps.com in the past about the Fan Shroud mod, but I couldn't locate any pictures to assist in the process and so I figured I would try it out and post the pictures accordingly.

As far as the why I keep the MAF sensor plugged in, I have the GDE eco tune (and the Weeks kit 1 & 2 EGR delete kits in place), and so I don't believe that it matters anymore (plugged in or not). I keep it plugged in so looks better for the smog check upcoming next month.

:)

Plus with it plugged in you can take live readings via an OBD scan tool to get an idea of rocker wear.

THANK YOU FOR POSTING THIS THREAD, INFINITE_KARMA!

This is a great set of photos... as you obviously know, a picture is worth a thousand words. :mrgreen: In this case, these photos are probably worth 100,000 words.

Did you have any trouble installing the Model 001? Several of your photos show it bolted to the engine, but there is no bolt threaded into the tab on the Model 001 housing that ties it to the steel bracket off of the viscous heater. I have a couple of questions regarding this...

1) Did the threaded hole in the aluminum tab line up properly with the steel bracket on the viscous heater? I see by one of the last photos you got the bolt threaded on, but I am just wondering of you had any trouble.

2) Did the 6mm hex key tool I provide with every Model 001 prove useful?

Best regards,

Hey Jeff,

I didn't have any problems installing the Model 001 thermostat housing assembly, and I waited on connecting the bracket bolt until I had torqued down the other three bolts first. Then I screwed down the bracket bolt without any problems.

1.) The threaded hole in the aluminium tab lined up tight, but just fine on the steel bracket. No problems at all, I just didn't take a photo of that step.

2.) The 6mm hex key tool you provided was perfect, and made the job that much easier (thank you for that). My torque wrench did just fine using it, gentle and consistent torquing. The only tricky part was removing the 6mm kex tool tip after torquing, as it kind of stuck in place. I just wiggled it free until it came out.

Very happy with everything.

Sarma

Cool... very, very cool. 8) This is a relief to know. I really hope my other customers give as detailed a response as you have, Sarma.

Thank you.

Jeff,

I also installed your thermostat (2nd Gen with the ports for coolant probes) and it went very well, thanks to the provided 5mm Alan). I ran into a small issue while replacing the thermostat (I put a 190 stant) and I'll let you know on an email. Nothing to worry the customers though. Very nice unit! I'll post some pics when I'm done with the whole work, I planned to replace the turbo, but the play is less than the new unit I have, so I didn't replace it. I replaced the ckp and I'll have to recheck the timing, add warmer pads for oil and trans, replace the trans fluid and add probe in the pan. So it will take a bit as I'm not in a rush, the crd is now my 2nd driver vehicle.

I am curious about the putting this fan in. I am looking for better options for mine.

Will the 11 blade fan bolt up to the Hayden clutch or does it need the gm clutch

On the Hayden HD Fan Clutch I got, the bolts lined up just fine, and when screwed down tight it is solid ... but the center hole in the 11 bladed fan was slightly smaller than the posting seat on the circular center of the fan clutch. I don't think it mattered that much since it was torqued down tight onto the fan, and the 1/4 inch extra width it created didn't cause any fitting problems between the intercooler area and the engine.

If anyone else has any concerns or recommendations for improvement for a fix, let us all know!

The GM clutch fits the fan opening perfect using the part numbers below:
part no.s
GM Severe Duty Fan Clutch NAPA 271625
GM 11 blade HD Cooling Fan NAPA No. 8552223

The OEM 11 blade gaser fan hole is slightly smaller and does not fit the clutch perfectly. Best to use the GM parts... :wink:

I probably should have installed the GM Fan Clutch ... :)

Ahhh well - we'll see if the Hayden HD Fan Clutch works with the current set up.

How has this installation worked for you? I've got a fairly new Hayden clutch and I'd like to avoid having to buy the GM clutch.

So far this set-up (The Hayden HD Fan Clutch + the 11 bladed fan) has been great. There have been no problems at all with the gap-seating nor the fan distance.

I drove 4 & 1/2 hours up to the Sierra Nevada Mountains to enjoy a snowy weekend in a cabin with my 2 kids, my wife, and some friends, and my Jeep & Yakima box was packed full. The entire time I climbed from sea level to 7000ft+ elevation, my temp gauge never moved off the exact midline.

I will be towing my 19' 4000lb travel trailer up the mountain in May to go camping with friends and family, so I'll be able to give it a truer test then.

I'll let you know how that goes.

:)

Thank you for the positive feedback, Infinite_Karma. Are you still using the 203 degree thermostat valve?

Yep! And I believe that the real reason the temp has been so consistent and responsive is due to the 4J Thermostat & Assembly, not really the fan and fan-clutch. I will keep you posted as well Jeff when I pull the Travel Trailer up the mountain and back in May. :)
