Hey guys, new member out of SoCal. I have a 2014 Mustang V6 and a 1999 Mustang V6. My question today is about the 1999 V6. While replacing the water pump on my 3.8 I somehow snagged this little sensor/solenoid thing. I cannot figure out what part this is so I can order it online. I'll probably just end up going to a junkyard to find a replacement but if you guys know what it is/have a part number, please share!!! Thanks ya'll.
