How's it going all. I really need some help with a cooling issue I have and I would really appreciate any and all help. A few weeks ago I was driving home from work and noticed my temp gauge alittle higher than normal. This is a 1973 plymouth fury with a 360 btw. So I noticed my gauge alittle bit high and kept an eye on it, the scary part was after a few minutes I had a very sharp and sudden temp spike. My gauge went through the roof and slowly dropped back down. So I thought the worst (blown headgasket even though I wasnt driving it hard) and pulled over. Checked my coolant level, it was alittle bit low and alot of air escaped when I released pressure from my cooling system. Topped it off and checked my oil. I didn't have coolant or oil mixing. So I babied the car home (keep in mind I daily drive my fury 180 miles every day) I noticed my temps would drop when going down hill and would randomly spike and then go back to normal. So anyways long story short I replaced the thermostat and the car was fine for a few weeks. Tonight on my drive home the car did the same thing again. I live in northern nevada its winter right now, we have snow, we are lucky to get above 40 degrees Fahrenheit right now. I've been driving this car daily for over a year now and never had an issue with it even in the hot nevada summer. So why am I having cooling issues now when its colder than hell. I havent changed much recently besides the belts and an alternator and changed the oil. Idk what my issue is, another thermostat? Should I run no thermostat? The first time I had this issue I put in a 160 degree fail safe thermostat and it did fine until tonight. I'm so bummed right now
