Slow blinking coolant light diagnosis

[runjmc2]

The solution/problem had nothing to do with the coolant/level. There is a temperature sensor that triggers the fan (around 75C) and then the blinking light (77.5C). The sensor slipped off it's position and was resting on the hot manifold.

Where is this sensor located?

Runj...you really need to check the coolant level. ;-)

Ditto Jager's question....I'd like to know where that sensor is. Congrats on a nice find.

I've got the same problem now. Yesterday, while driving home in cool temps (70s) I hit a bump on the road. Right afterwards the red light started blinking slowly.

The engine temp is running at its normal position. I drove home and check the coolant when the engine was cool, and it was full.

This morning I started the car and within 1-2 minutes the red light started blinking slowly. The temp needle was still cold. As I drove to work the needle came up to normal, and the light kept blinking.

This summer I did hear the engine compartment blower running once, so I know it worked then. I don't think it is running now.

Maybe my engine compartment temp sensor has "slipped" like the poster above. Can anyone post a picture of this sensor?
