Actually when the truck's running hot, there no signs what so ever.
My expansion tank has a few pin holes and there is signs of leaking,
but not enough to create a small puddle. Plus I spilled a bit of water
on the side of where the expansion tank is and the water ran down the right bottom side of the truck.
I'm really starting to think it's the water pump?
