Triumph tiger 955i radiator fan doesnot shut off

This is for a Tiger but should be close.

Radiator cap is bad. The reverse valve on the cap is stuck or damaged. It is not able to pull fluid from the Radiator overflow.

You can get a relay to do that. Sold on Ebay..

Yes it will cause overheating. It sounds as if either the fan is open circuit or there is no power getting to the switch.
Hope that helps.

If you look at the front wheel, now look about six inches behind that. Theres a hex nut right below the exhaust pipe coming out of the engine. Should be at the lowest point on the engine in the front. You have to remove the skid plate.

FIRSTLY CHECK THERE IS SUFICIANT COOLANT IN THE SYSTEM, SECONDLY YOU HAVE A FUSE FOR THE FAN HAVE YOU CHECKED THIS?, YOU HAVE A SWITCH IN THE COOLING SYSTEM NORMALY IN THE RADIATOR THIS SENSES THE WATER TEMP, AND SO ON ACTIVATES THE COOLING FAN, IF THE WATER LEVEL IS LOW THE SYSTEM WONT GET UP TO TEMP, IT MAY BE HOT, BUT THE TEMPRETURE METER READING IS MEASURED IN A DIFFERENT AREA NORMALY AT THE THERMOSTAT AREA, IF ALL ELSE FAILS LOCATE THE THERMAL SWITCH ON THE RADIATOR AND REMOVE THE WIRES AND BRIDGE THEM WITH THE IGNITION OFF, THEN TURN IGNITION BACK ON AND THE FAN SHOULD RUN PERMENENTLY, IF IT DOES THEN YOU KNOW THE REST OF THE CIRCUIT IS OK AND SHOULD GET THE THERMAL SWITCHED CHECKED OUT, AND REPLACE IF NESS.

let is sit for a day and dry out. you probably got moisture into the spark plugs, or the distributor, or the wires. if you have a battery charger, charge the battery while you are waiting.

JUST A SHOT IN THE DARK ON THIS.

TRY DISCONECTING THE POSITIVE POWER CABLE ON YOUR BATTERY,AND WAIT TEN OR TWENTY MIN.THEN PUT THE POSITTIVE BACK ON IT.

SEE IF THAT WILL RESET IT.

HOPE THIS HELPS
