So my son drives a 2014 1.4. He called me friday saying his temp gauge spiked. When i got to the car there was no fluid in the resivior and antifreeze was everywhere around the pump. No problem, i got this. Changed it out yesterday, easy enough but i am concerned. I can't get the thermostat to open. what confuses me is the temp stays at 195degrees noted with temp gun, not the gauge. I ran the car for 20 miles yesterday and it still didn't open, or go above 195. the temp gauge reads 185. How do i get the thermostat to open so i can properly fill the system? Am i missing something? Thanks!
