temp light
 

Within the last week or 2 the temp light comes on as soon as I start my truck its a 250 6cyl. Has plenty of water and must be circulating cause heat blows hot air. Where is the sensor located on the engine?Any help would be great! :b69:

Well, yours should be in one of two places. somewhere around the water pump or right ... here (look for the black wire with the white plastic tip on the left-hand side):
