I bought an alloy radiator to install, but when I looked at the stock radiator it has this electrical plug next to the pipe on the Bottom of radiator, the alloy radiator doesn't have one, what is it? How do I make it work in the alloy radiator, do I need to get one welded on? Or is there an easier solution?

That tells the ecu when to switch the fans on..yes it is needed.

So what are my options on making it work with the alloy radiator?

You can either have a bung welded into the rad as so you can bolt the sender in (the right way), or hardwire the fan to a switch and manually turn the fan on and off (the wrong way).

 

As someone who has their rad fan hardwired to a switch, it is a PITA. Do it the right way.

Only takes one time to forget to switch it on and its game over!
Options are...
Get correct radiator for your setup
Pay money to have a bung welded in
Change to Evo Ecu that doesnt require that plug.

Ok thanks, I might wait until I upgrade the turbo and run an Evo Ecu, there's no way I'd remember to turn the fan on and off every day

Or you could buy one of those adapters that mount the sensor in the lower rad hose!

Yeah I did see something like that, but I thought it must of only been for running a temp gauge or something, will one of those adaptors work properly?

Or you can get a short section of alloy tube the same outer diameter as your rad hoses and have a bung made to suit the sensor

You could get the hole drilled and tapped bigger to suit the sensor if it's not right

Are those screws in the corner of the alloy radiation not able to be taken out and the sensor installed?

[mat]

I think the screw hole is to small, but in saying that I don't really know how big the sensor is

[Missile]

If it is too small then you could just drill and tap.

Or alternatively im sure there is a temp setting that suits that tread of the bolt.

From memory the factory temp sensor thread is 3/8" BSP.

Ok thanks, ill look into it
