Changed Thermostat now coolant leak
The truck was overcooling so I changed the thermostat and after determining the fan was working right. After changing the thermostat and gasket, I filled it up the radiator and started the truck. No leaks after up to temp or under a load so I drove it around and check again, no leaks.
Parked the truck in the garage and took a peak an hour or so later and saw coolant on the ground, a couple of cups worth.
Trying to figure out where it came from? I dont see any coolant in the valley and the expansion tank has fluid in it.
Could it bet that I overfilled it and it leaked out the expansion tank?
Valley is dry both in the front and in the back (what I can see).
