Thank you for the recommendations! The ML's waterpump went out on 95 South and as soon as the temp started climbing the wife called and I told her to pull over. Later it was towed to a shop about 15 miles away in Richmond where the waterpump was replaced. After testing, it was given the thumbs up and we used it for a couple of weeks but around 300 miles later I smelled coolant at the tailpipe and saw steam from the tailpipe after a drive to Richmond so it is at another shop. The shop said the headgasket is toast and is looking to replace the motor with a reliable used one rather than try to rebuild the original with 170K. I'll check into these shops for the other cars and keep ya'll posted and update about our experience at the one in RVA.
