Hey y'all I've just picked up a lovely 1971 144S. Still had plastic on doors and only 155k! Within a few days of getting it the temp gauge started to go higher than it was going (especially when the headlights are on?). It's almost hitting the red now. I think I should replace the thermostat to start since it is a simple fix and probably hasn't been done in some time.
Any suggestions on thermostats? There are a number to choose from. I live in Colorado.
