Alright, desperately seeking someone with some knowledge!
I have a 2007 Ford Edge SEL V6 3.5L
Ive had very few issues with this vehicle over the years. Saturday I took it to an oil change shop for a regular oil change when they told me my serpentine belt was cracked and needed replaced. Theyve told me this the last few times, so I figured I may as well go ahead and replace it. It takes them about 25 mins to finish everything up and Im on my way. I drove the car around 100 miles, and out of no where my heat stops working. Check under the hood and my antifreeze reservoir is bone dry. Take it back to the shop, where they tell me they forgot to fill the coolant, run it a few minutes the heat starts working, everything seems fine. I take it home and park it. Later that evening, I leave to run an errand and once again the heat isnt working and the reservoir is empty. And now a check engine light (crank position sensor) has come on. I refilled the reservoir once again, and decided to take it to a friend to have them look it over. On my way there, the car starts to overheat for the first time, I pull over give it about 20 minutes to cool down, add more antifreeze and go to start the car again with no success. The battery is dead. Nothing was running in the car while it was off with the exception of the hazard lights. After calling a tow and getting it parked we find antifreeze in the oil.
I guess my question is, is there any way this is a connection to the serpentine belt that was replaced? And how. Or just a major coincidence?
