A fitting comes loose due to adhesive failure resulting I loss of all or most of the coolant fluid. The repair requires engine removal and repair of the fittings. There is some issue as to the proper or best repair approach. What is know is that the adhesive failure is almost sure to occur. …”

“Yesterday as I was driving in freeway, my friend was following me from behind, he noticed smoke and coolant leaking making his car's windshield dirty. So we stopped at gas station and noticed good amount of coolant leakage from underneath which make the back of the car and tires big mess. I noticed, before my friend's call, the handling and grip of the car was little off, I didn't know why but then I realized leaking made the tires slippery. Tow the car to my house and just wanted to report this. It seems lot of people complain about this issue when I started reading about it last night.”
