So just finishing up some minor electrical stuff (lights,fuses, and bad connections) My radiator fan came on (while the engine is cool) and won't shut off until 15-30 mins and sometimes even longer. I have tried looking it up but only find overheating related causes. Is this common? or just something odd?

 

Prolly a bad fan switch on your thermostat housing.
Start by replacing that.

 

or a short in the wire causing it to be jumped all the time inspect them.

 

Disconnect the fan switch, if it turns right off the sensors having issues. Check wires as well, they do deteriorate over the years.

 

So I ordered a fan switch and fan relay to try tomorrow. My battery is dead atm so I will charged it and try to determine the problem. Thanks again

 

USDM Integras have a rad fan control unit that is triggered by an oil temp. switch that keeps the rad fan on if oil temp is high enough even with the ign. switch off, the unit can fail keeping the rad on at all times.

The first thing to do is unplug the oil temp. switch, if that solves the problem, replace the oil temp switch, if not replace or remove the rad fan control unit, CDM Integras do not have the rad fan control unit, it is some kind of EPA requirement. 94

 

Oil temp switch? All right I will order one of those too just to be safe. I am going to check wires when I have some daylight also. Thanks for the info

 

Sorry, I did assume you have a G2, [90-93] if so continue, however, do not waste money buying parts you may not need, unplug the oil temp. switch first, to see if it is the problem. 94

 

Thank you so much my Teg is now running right! It was a loose connection on the temp switch and one bad cooling fan relay. Next step is aftermarket mods like air intake, coilovers, gsr wing, and much more Thanks again, now I can at least drive it for now before I do any of that haha
