looks good buddy!...does anyone know how much bigger a 2nd gen radiator is than a 1st gen radiator? sorry to derail the thread.
Those PWM controllers are interesting. Definitely out of my budget, but it's good to know they're available. Thanks for linking them. From what it sounds like, your fan control system will make the active cooling much smoother than most. :thumbsup:Awesome writeup! Couple of things to throw out there... This company has a solution for mounting the switches to contdol the relayz in the return hose to the radiator Mark VIII Fand Relay Kits i will be using them when i get my fan project under way.
2nd, if you run into a cooling issue with the setup consider a divider between the 2 fans so eac h fan will work truely independent from each other.
My plan is to use the hollister parts & switches with two switches that are offset from each other so fan 2 kicks on low at a higher temp than fan 1, with the divider installed and fan 1 on with fan 2 off fan 1 should pull more thru it side of the radiator core and do a better job at cooling.
Just installed a 3 core btr radiator in my '05 and will be shipping the core rad home when done here in MN. Planning on finishing the cad dwg i started and gdtting it dialed in with the volvo fans & controllers so the install is as quick as possible and easy to pull if needed...
Looking forward to hearing how your setup works.
Hah! Thanks! I wouldn't quite call it Diesel Disneyland, but it is a pretty cool place. All of that was done at home except for the TIG welding, and that was only done at work because I brought my personal welder in.Wow...do you work in Diesel Disneyland or is that home....
I am soooo envious of those toys...
Derp. :doh:Just to clarify, the link was for the fan switch sensors and the 2" sensor inserts that would go in the return line to the radiator. I wouldnt use the pwm setup for control, too many complaints on them failing, the oem volvo control unit is the way to go. Easier to get i would think.
Looking forward to hearing how it performs for ya...
