I started finding under the truck here and there small puddle that look like water. But when I put my fingers in it smelled sweet like coolant. Its going in this week to get checked. I suspect its the water pump? The truck still has the oringal pump. But I am keeping my fingers cross that its not the intake manifold. If it is I have a big problem.
