Sounds like either the thermostat, air in the system or the otterstadt. If you are unsure you can replace both. They are easy to do. Thermostat is just taking some bolts aout and replacing it. The otterstadt is under left rear cooling pipe. Make sure th wires are hook up to it and are clean. You can test jumping with a paper clip in each plug at the otterstadt. If you have air you need to bleed system or install the self bleeder. I also get the last but of air out of my system by barely cracking the small bleed hose at the radiator. If you hear a sucking sound you had lots of trapped air in your radiator..
