Heater core failure
Well, it happened to my 1993 Eurovan finally. On one of the hottest days of the year, I’m almost certain that my heater core has failed. Smokey air through the vents and fogging started. I pulled over and saw the leak. Then I tried to get to a better location and coolant came through the dash. Here are some photos. I have purchased a bypass kit and will install this weekend. Wish me luck.
