I have a 93′ Buick Roadmaster V8 350

Even though my heat works it takes a very long time to get hot..my coolant guage on the dash says very low, never get into range and usually by the time i get to work about a 15-20 min. drive i have heat....do you think i need a new thermostat...This car has automatic climate control. I've never really messed with these systems before, they sure are a pain. You set your temperature and the heating and cooling are automatic around that temperature. thanks john
