The truck has been great, until we noticed low coolant levels and severe temps w/ little to no heat generated from heater. We top off coolant levels and before we can drive 20 miles the heater blows cold and all the coolant gets spit out of somewhere around the distributor/ rear of the engine. The leak is not visible from any angle, that's what is making me lean towards a gasket problem, a burnt water jacket on the intake maybe. There's no coolant in the oil so the head gasket seems like it's still good. I hope it's not going to be a huge pain to find, & fix.Wish me luck it's the only form of transportation for a retired grandfather/ guardian of three, with a disabled wife on a fixed income.
