I pulled the washer reservoir and noticed vacuum line that runs from the bottom of that switch to the manifold area was not connected, hooked her up and drove < 2miles, temp went to 115 and many "gurgling" sounds coming from dashboard area. I then unhooked same vacuum line but temp still hovering around 120 and gurgling sound from dash continue. I noticed a third nipple on topside of that switch under the reservoir but no loose lines in the vicinity. What's going on here? Did my thermostat crap out on me incidentally?
