Hey folks,

New here very happy to find a site in Oz for Datsun's/old Nissan's (or at least I hope the Urvan is welcome here :D )

I picked it up last night knowing it had some issues and this is what i noticed . . .

The fan is really loud on pull away 1st, 2nd gear . . . then it quietens down. Every time I stopped at a set of traffic lights the temp gauge started climbing up to half way and just past in some instances, and no sign of the fan shifting to a higher speed?? Along the highway though the temp gauge stayed about a 1/3 of the way. When I spin the fan by hand (engine off cooled down) it stops as soon as my finger leaves the blade almost. I've checked the oil and coolant for any signs of head gasket damage and both look ok. Thinking if it's not the fan perhaps it's the thermostat.

What brand water pumps and fan clutches are people using in Australia?
