I need to get off my ass and put mine in. The upgrade...
Been settin' on the to-do shelf for a freakin' year now.

Not exactly like you've been sitting around though! Anyway, I'm getting mine this week. Your challenge: have yours in before mine.
My engine just gets so blazing hot that I customarily raise the hood (sometimes just the first latch) at each stop to let it cool. I've come out more than once to, "HEY MAN! SOMETHINGS WRONG WITH YOUR HOOD!"
This little mod should help.

Easy install, except watch out for the temp sensor. Make sure you either epoxy it to the bracket real well (good idea) or strap it real well. The original "glue" gave up pretty quickly. That said, GOOD mod, and it really works well!

The instructions I got weren't that fantastic... what is the best spot to put the tempurature probe? picture?

The new kit, or the old kit?
I have the older kit on my car, and the new kit upgrade sitting on a shelf waiting to be installed. I think the probe is different from the old to new kit which is why I ask what kit you have.

I purchased my kit November of last year... would that be the new kit?
My probe is about 6 or 7 inches long, and about the diameter of a pencil...
I don't know if it's the new or old....

That would be the new kit. And seeing as I have not opened the package yet I'm shooting from the hip, but I do remember seeing what looks like a capillary and bulb in the bag. Or what you are calling the probe.
Maybe I'll open up the package this weekend and take a looksie at the instructions.

Yeah, let me know if you can figure out a good position to stick the probe... cause other than sticking it directly in the fluid, hahaha, I don't see a spot where it can get a good reading.

Uhhh, stick the probe...what are we talkin' about here??? Hope you got a nice nurse for this job!

I slid mine right in between the fins of the radiator right next to the upper radiator hose. It gets a good reading from there and works like a charm.
With all the sticking and probing, this thread has great potential to degenerate qucickly...

Do you have a pic of exactly where it is? does it have to be against the metal to get the reading, or is it getting a reading from the 'air' surrounding the area?
And yes... I totally agree!

The sensor bulb will read whatever makes the temperature around it what it is. You would prefer to be reading the coolant temperature inside the cooling system, but since that is not an easy option, then something in intimate contact with the fluid that has good thermal transfer properties.
Aluminum has great heat transfer, the rubber hoses do not. The air surrounding the cooling system parts is too many steps removed from the actual coolant temperature, and there would also be a noticeable delay between actual coolant temp, and the time that the sensor bulb gets that temp and responds to it. Like turning the fan on.

The bulb sits in direct contact with the metal of the radiator. The "old" system had the sensor that was connected to the thermostat housing. Same idea with the new system, just a different location, different sensor, and better design.
I'll see if I can get some decent pics of it tonight.

I'm also trying to install the new fan control kit. The problem with mine is that I can't get the probe into the fins through the small gap next to the upper hose. I swapped emails with Sean (Roe) and he told me to loosen the fan shroud to get at the fins. Has anyone else had to do this? I'm not familiar with the radiator and the fan shroud...some instructional help would be greatly appreciated!

Just pull the airbox off, and then the fan is so right there in front of you a cave man could finish the job.
You do know how to get the airbox off right? The nut holding the fan on to the radiator should be 10mm wrench size.

Thanks! I've had the airbox off, so I probably can manage that ...maybe I'll get to it tomorrow. Once I get it done, I'll take some pictures and post them accordingly.

Beauty! And don't be afraid to loosen more of the nuts along the top of the fan (there are 3 on top, 2 on bottom) if you need to pull it back more. It is flexible plastic.

My car is getting its hinge replaced on the passenger side right now, so I'll probably attempt this weekend... although I would still appreciate some pics.
Obviously the plastic zip-tie's are not good enough to hold the probe in place on such a hot surface like the rad... what else should I use?

The upper recommended service limit of nylon cable ties is 185 deg F. Your radiator is right on the edge of that.
You could use stainless steel wire. Probably get it at Home Depot etc.

Here's some pics (yes, I know my engine bay is dirty):
I haven't had any issues with my zip ties. I imagine steel hose clamps would be a cheap alternative.

As I previously stated...The problem with mine is that I can't get the temperature probe into the fins through the small gap next to the upper hose...so I needed to remove the fan shroud and here are the pictures...
Thanks Dave...nut size (10mm) and number of nuts (5) is correct, of course.
This is the fan shroud...
This is the relay (on the PCM cover) and ground...
This is the power (yellow connector) and in-line fuse (red one)...
This is the fan control tap (yellow) and temperature control box (on the backside of the headlight housing)...
This is the temperature probe inserted into the radiator...
This is the gap at the top end of the radiator...

If I remember right, I just drilled a hole a little larger than the probe in the fan shroud to get it through. Just be sure you don't drill into the radiator!!

I will probably have to do that. I put the Roe triple pass in last weekend and there is no gap at all at the corner of the fan module to see the fins - the end tank is to the fan. Nothing a Dremel or drill bit won't cure.

Heres the problem with mine....
I finally got the probe in where 'Sweet Ride' put it... wasn't hard at all, just needed to know a good place. Anyways, I ran my car until I got to the tempurature I wanted it to turn on at, and then adjusted it to when I wanted it to turn off. once I did that, I turned the car off.... and within 30 seconds, it turned on again. So I lowered the adjustment so that it would turn off.... closed the hood... came on again.... lowered it again till it turned off... closed the hood once more... came on again...
etc.... it did this about 10 times... at this point, the tempurature on the gauge is below 90... which leads me to believe the fan will probably stay on now for like 10 minutes after the car is off. Is this right??
lol, let me know.

Part of the idea of the fan control is that it will continue to cycle the fan when the car is off to prevent heat soak. I originally set mine too low and it ran constantly after I shut my car off and drained the battery. I now hit the sweet spot and it runs for a couple minutes after I turn the car off (in 110* temps) and then cycles on and off every couple minutes for about 15 minutes total.
