Water Temp

[R31Nismoid]

Ye maybe - mine sits super low... lol. I dont very high as stated unless its a stinking hot day!

That's using different temp sensors as well just to be certain none of them were stuffing up etc.

do you have your stock under shielding to help (air pressure in the engine bay IIRC), was reading something about this on the Datsun forums where overheating is more of a big deal lol

Nope - its all free underneath mine.

must have something do with the 31 being box shaped, therefore having more wind resistance and a greater cooling effect

[JonnoHR31]

or maybe they just dont make enough power to produce any heat

Sounds like your waterpump isn't functioning properly or your radiator is blocked.. When was the last time you had

your cooling system checked and serviced

Waterpump has been checked and is working well. Radiator flushed about a month ago.

Jonno, I'm using a Koyo 50mm aluminum radiator + clutch fan and shroud. After investigating today, I think my clutch fan may be shagged.

Will try another one and see if that helps.

when does the thermo fan turn on??

[JonnoHR31]

what thermo?

[some_cs_student]

what thermo?

He may be referring to the small fan that sits in front of the radiator near the horn.

I cannot recall when it activates...

[PM-R33]

That's for the aircon.

[JonnoHR31]

exactly. completely irrelevant. clutch fan is resposible for airflow through the radiator, not the a/c thermo

No idea about 33's, but on a 32 the electric fan out the front is an engine exessive temp fan, can't remember when it comes on. You can bridge it to come on with the aircon, but you have to make wiring modifications for that to happen.

The last hot day I was out in mine, I was hitting about the same water temps as Brockas, everything in mine is stock though..
