Yeah you want your temp to hover between 80 and 90 thats fine... definitely measure the pipe first

As for the relay, the temp switch will switch the relay on, and the relay switches on the fan motor.
this saves the temp switch from having all the power for the fan put though it

Click Here for Ebay Listing


you will need some wire, a fuse holder and a 30a fuse... and some crimp connectors (ring and spade)

For some more information on relays, read this page:

thanks dude, so at the moment is the standard fan switch in the rad taking all the power that the above relay would?

not sure on the TD setup... but possibly not.
You should be able to hear it click and activate when the engine gets to about 90*C, when the fan would usually activate
