I have had a Hayden Rapid Cool Radiator Misting System sitting in my shed for a about six months and with the hot weather on the way (down here in Australia) I decided to go ahead and install it. Details of the system can be viewed here:

I bought it because I never wanted to worry about heat again (as some will know just one step in many I have taken to have a cool running CRD).
The tank is fairly large and cannot fit in the engine bay, and I tried to put it on top of the transfer case bash plate but that doesn't cover the rear corner of the tank and it would be a problem to fill. Inside seems the only option. I mounted mine on top of my storage unit and secured to the cargo barrier:
It's designed to be relocated if I need the entire rear cargo space on a big trip, and it can sit on the rear floor behind the seats (there is enough tubing and wire to allow this). I may make up a ply mat shaped foot for the tank to mount on the floor behind the drivers seat, (like the battery box that I already have for the rear passenger side).
I ran the tubing through the left side chassis cross rail (to protect it) and bought it out just behind the front wheel running it up the firewall and around the battery and out the bottom of the grill to the TJM bar. The rear end of the tube exits the chassis rail and goes through a hole in the rear floor (corrugated tube protected and Sikaflexed sealed) and up to the tank location.
At the front Bar I ran the tube out to the light bar and mounted the nozzles on that just behind the driving lights and aimed at the radiator (they snap into mounting brackets which are pop riveted in place). There is a 'Y' junction in the tube kit and this is used to separate the main feed into two for the two nozzles.
The pump motor has a two wire supply and earth which plugs onto the motor contacts. They supply a momentary push button for dash mount but I wanted it to be removable so I made a push button stalk out of a 12V plug adaptor as shown:
This is really easy to use as you just reach down and push the button.
The wires are run (in tubing) under the read seat and up next to the console. The 12V Male adaptor plug is fused (10 amp) so there is no need to worry about that. It is abit fiddly to mount the push button on top of the plug but it can be done.
Works well in testing. From ambient air temp of around 76F, I have managed to get a drop in displayed temperature of 1/2 to 1 full notch on the temp gauge with a couple of ten second blasts of the jets. You can hear it running so your not likely to forget about it and run the tank dry (and you'd have to hold the button until it did anyway).
I need some really hot temps to get the definitive data but it looks like a worth while mod for people who plan to tow in hot weather or have long climbs with heavy loads.
Other cooling mods include: hood venting (Synergy vents from Quadratec)
