72zcar Posted January 15, 2003 Share #1 Posted January 15, 2003 I am installing a new electric fan on my L28 in my 71 240z. The old fan (before i bought the car) had the fan thermostat sender was under the top hose on top of the thermostat (radiator side of thermostat)Is this right? it seems like it should be on the engine side of the thermostat... someone set me straight where to install the fan sender......thanks:stupid: Link to comment Share on other sites More sharing options...
Daniel Posted January 15, 2003 Share #2 Posted January 15, 2003 I can't speak of your exact fan type but,I have seen this set up before.I must assume yours is correct.Since there is no place between the thermo and motor to put one. I guess they figured with the thermo open you get a more correct water temp reading on the rubber hose than mounting on hot metal. Daniel Link to comment Share on other sites More sharing options...
halz Posted January 15, 2003 Share #3 Posted January 15, 2003 Thats right. You don't want the sensor telling the fans to come on for a few seconds as the engine is warming up (ie. before the thermostat opens). The fan is designed to maintain airflow through the radiator when the cooling system as a whole creeps above the engine's ideal operating temperature. So... put the sensor between the radiator and the thermostat. Link to comment Share on other sites More sharing options...
