Default Flashing Blue Coolant Light

This is weird. According to the owners manual, it means there is some error in the cooling system. Usually, a simple restart of the car solves this problem and it doesn't happen again for a week or so.

Well, i assumed that the change of my timing belt and waterpump would solve this, but it didn't. It just came back on today while i was on the highway.

Also, i have that strange problem where about 15 minutes after the blue temp light goes off, it comes back on. I'm thinking its a sensor that wasn't included in the timing belt change....

My guess is the Coolant Temp Sensor, but i'm not sure on this one. I don't want to replace something that doesn't need replacing because my pockets are a little light from this temporary unemployment.

Anyone know?
