Radiator Fans Running Constantly?

[MaseratiMike]

Changed my radiator....... What a pain! Let me start by saying this car should have been recalled for the fact that the radiator was made so vulnerable. It hangs about 3 inches below the frame of the car. I went into a u-turn and up on a simple curb that rook out the radiator.
Question: after replacing the radiator I noticed the cooling fans are on constantly now. I never noticed until I started thinking about the number of comments on how loud the car is at idle. Any suggestions on what caused this? And I assume it will eventually burn out the fan motor?

Stuck or damaged solonoid or not connected correctly, I doubt it would be stat related.

The rads will turn more if the AC is on, switch that off first.

if not, check the relays under the bonnet and also check the fan resistor in the fan shroud, you probably damaged it or put it back wired wrong.

Relay; solonoid what am I like!

Run an ODBII scan if you can, might show a related fault, e.g. if the thermostat got damaged. I've had one throw a fault before so it's not unheard of. Cheap fix if it is.

Mine did this a while back when battery was near EOL. Only way was to do battery reset for me but the guys may be right in that something is not back in place as it should be.

Hi mine had that fault when i got it running and it was the temp sensor on the engine, the plug was not pushed on correctly so i think the car thought it was over heating and put the fans on!! Pushed the plug home snug and its been fine ever since.

^^^^^^There you go Mike I recon that should sort your issue. If the plug is on correctly, check the wiring for continuity and if ok just replace the temp sensor, I know its a cheap part.
