Primary thermosensor removed from original rad, placed in EGR thermoswitch location. And then wired to trigger both fan relays.

His fans turn off and on just fine. I wouldn't have approved it if they stayed on all the time, that's for sure.

Well my set up works...sooooo...

i just did the same swap and i installed the secondary switch in the drain hole of the radiator just drill and tap it to M16-1.5 works great. thanks StarQuestMike

the main question is how hot is the rad coolant , lets just say the fan sensor is in the intake,,the thermostat fails to open the fan run cause the intake is over heat'd but does the coolant get cool'd nope cause of no flow to the rad ,, be a real pain to trouble shoot wouldn't it, cause you'd think well the fans do run so it must just be the gauge off , few people actualy lay hands on the rad to see if it is hot or not

check this out.

 

this is an alternative. the screw is for a ground wire to the engine block.

just splice lower radiator hose then clamp it down make sure to run ground wire.

on a side note the stock mitsu sensor might not fit. you might have to drill tap

hole to proper thread pattern or use a different fan sensor.

the link below does come in different sizes so make sure to get the proper size

for the quest hose.

this is called a radiator temp sensor adapter. search for one.

yeah that's a problem then so ill see if I can get a bung welded in the rad and run the two fans off that one sensor but is the cx racing rad thick enough to weld?

Derale also make a adjustable thermo fan switch with a probe sensor that goes into your top radiator hose for around $30 and can be found on Ebay , easy to install and works great ! , i went this route using the same radiator you just bought :) Edited by SOTTY

Then i guess both Derale performance and myself are both wrong , the capillary tube and probe sensor is inserted in the top radiator hose .

I suck at internet mang , Derale performance , Los angeles , C.a the part # is 16769 ,punch that into your computer and it'll come up, it's very easy to install , no tapping into the rad whatsoever , comes with everything you need , it's a very clever set up that works very well and powers up to two 12" fans . :) Edited by SOTTY

lol who do I trust

oh that ones easy as i won't give out wrong information on something iv'e tried and tested myself and i have the installation instructions in front of me as i type with the detailed drawing of the radiator top hose showing the temp probe inserted and do yourself a big favor no matter how broke you are and buy two cheap Ebay 12 inch fans and the ties to attach them to mang , don't mess trying to adapt the stock fans , that and there probably getting to old to be of any use like other things in the Starquest world ;)

you just have to get a different fan sensor form jegs or summitracing.

 

the sell them to fit in there.

Also just make sure you have a good ground wire.use a meter to test it.

used it before on an eclipse and had no problems.

 

http://www.ebay.com/...r-/121033753578

$6.99

in the pic below you can see the grounding screw.
