To test the temp gauge simply take the temp sender wire to ground and see if the needle on the gauge moves.
Afterwards recheck all related fuses and relays.

Steve,
There are 2 live and 2 earth mate.
Also remember that they are twin speed.
You will not do any harm if connected up wrongly for a split second.

Steve,
To test you can take a direct feed and earth to the fan motors.
The motors can be stripped and cleaned or you can simply just purchase replacements.

Good to hear from you mate, and hope all is good.
Alex.
You should have bought from me as you are guaranteed the correct parts and they would have been cheaper.
The oil filter that you have been given is listed for a Micra.
It is also the filter now listed for the 350Z..
