Can a battery coolant heater replacement cause coolant leak?

Hi all,

I had to have my battery coolant heater replaced in February for my 2015 Model S when I received error messages that said "vehicle may not restart" and "acceleration and speed reduced". During this service appointment, they also seem to have topped off the coolant (the coolant is listed on the invoice). About a month or so later, I noticed that my car was leaking bluish liquid while it was charging, and Tesla is saying that I need to get the four way valve replaced. I assumed this leak was related to the service appointment in February and would be covered by Tesla, but the service rep said they are not related. He explained that the parts are about 6 feet apart from each other so the valve would not have been affected during the coolant heater replacement. My question is, is there any way something could have happened to the valve while they were topping off the coolant? Or does anyone know if they would have come in contact with the valve at all while they investigated the issue in February? Any and all information is much appreciated. Thank you!

Most likely just the part failing and timing is just close to your coolant heater replacement. That valve has been known to fail. There was a resurrected thread on replacement of that part that you can DIY with little fanfare if you clamp the lines properly.
