You can trigger it with a Durametric, or you could jumper the relay.

If I jumper the relay, how would I know if the relay is working? Wouldn't it be easier heating up the sensor ?

It would be one Hell of a lot easier to just connect your Durametric and switch it on.............

I would if I had a durametric, but I don't have one unfortunately!

A quick way to check the fan itself is just unplug it from the harness and hook up a +&- to it. It's only a simple fan motor

You bought a Porsche, but a Durametric! It will pay for itself in short order.

When you jumper the fan relay, the relay is taken out of the circuit. With the jumper in place, the fan should turn on - if it doesn't, then the fan or wiring is the problem.

Please take a look at the link that Rick posted for details on how to jumper around the relay: Engine Compartment Fan Manual Switch
