When the engine is cool, you need to add coolant to the radiator. Just filling the plastic reservoir is not sufficient as this is your overflow. Hope this helps! Regards, Howard
I checked the pulleys and they are not loose. After I put the coolant in the radiator, the noise stopped....temporarily. Its quiet with the truck running for about five minutes, then it starts with the squeeking noise again.
Try spraying some WD40 on the belt to see if it quiets the noise. Also, it is possible you may have overfilled the coolant. I would take the car for a drive around the block to try to blow off any coolant residue that there may be. Then, when you come back, park the car in a different spot and let it run for 10-15 min and see if you see coolant leaking. If you do, there is a good chance you may have a leak in the hose. Even a pinhole leak can dump copius amounts of fluid :) Try this and get back to me; I'll be here waiting!
