Fans
 

Hi all after having trouble with my fans i brought another new sensor and coolant cap run the car up as the gauge past half way still nothing started creeping towards the red and about to swich off i looked and they was on but slow and it brought the gauge bk down does this seem abit high before they come on no sign of it boiling up or anything

All beyond me I am afraid.

Do the fans run at speed if you wire them straight up to the battery, If you can do that.

Maybe they are knackered, not on the sensor side.

Is the temp sensor the correct one? Could be set to the wrong temperature to ensure they throw the relay to turn the fans on.

The fans come on high speed when sensor unplugged i have got the sensors from rover spares by me correct part numbers it gets to 3/4 just over till the fans come on and they do bring it back down id of thought it would of been half way or just over i can hear the relay click on and off in passenger footwell

Plug in an OBD2 reader and see what temperature the ECU is seeing.
