Hey guys thanks for the responses. Sorry its third party, but its a friend a few hours away that is relaying info. I asked him exactly what was happening. He stated that his temp guage would start to rise above normale operating temp and then at stop signs it would be hesitant and stalling. Last time out he pulled over b/c it was running rough and opened the hood to white smoke. I asked if it smelled like coolant, but he doen't remember it smelling like coolant. Any thoughts for him? Thanks in advance.
