Wtf

[Blue93G20]

I can't figure out my problem with the radiator fans coming on. Any more suggestions cause right now my car is just sitting and you know thats got to be disappointing after doing a swap....HELP






P.S. this is BULLSHIT

But isn't that a good thing? Or do you mean your radiator fans don't come on?

That's what he means.

Fan clutch(es?) installed correctly? That could be the problem, but that's kind of a shot in the dark.....

hey jd u live anywhere near central? thats where im at now

You mean CCSU? I'm not far from there at all. Although on Mapquest, Monroe is about an hour from me.. which isn't all that far.

Since no-one has replied yet, I'll give you the lowdown on the engine temperature sensor according to Haynes manual for UK Primeras:

Engine Temperature Sensor

The engine temperature sensor provides information to the engine management electronic control unit to control the fuel and ignition systems, and the radiator cooling fan.

On all models, the sensor is located in the inlet manifold, at the rear (timing chain end) of the cylinder head.

The sensor contains a thermistor - an electronic component whose electrical resistance decreases at a predetermined rate as it's temperature rises.

The fuel injection/engine management ECU supplies the sensor with a set voltage and then, by measuring the current flowing in the sensor circuit, it determines the engine temperature. This information is then used, in conjunction with other inputs, to control the fuel injection/engine management system, and the engine cooling fan.

If the sensor circuit should fail to provide adequate information, the ECU back-up facility will override the sensor signal. In this event, the ECU assumes a predetermined setting which will allow the fuel injection/engine management system to run, albeit at reduced efficiency. When this occurs, the engine warning light on the instrument panel will come on, and the advice of a Nissan dealer should be sought. The sensor itself can be tested by removing it, and checking the resistances at different temperatures using an ohmmeter (heat the sensor in a container of water, and monitor the temperature with a thermometer). The resistance values are given below.

DO NOT attempt to test the circuit with the sensor fitted to the engine, and the wiring connector fitted, as there is a high risk of damaging the ECU.

Engine Temperature Sensor Resistance Values:
20 deg C ... 2.10 to 2.90 kilohms
50 deg C ... 0.68 to 1.00 kilohms
80 deg C ... 0.30 to 0.33 kilohms

Electric cooling fan cut-in temerature ... 82 to 88 deg C

Good luck!

yea im at CCSU sure gets boring here on the weekend. ill prolly have 100 posts by the end of tonight
