Overheating
2005 Grand Prix GT 3.8 non turbo. So I just changed the radiator over the
weekend. Poured in a radiator flush cleaner and water afterwards. I ran car
normally short distance for 3 days to cleanse system. During those days I had
"No" problems. Flushed radiator, installed new coolant and thermostat. Now
just by warming up engine temp. Gauge reads "Hot"! I started engine with
radiator cap "off" and thinking I would need to top off coolant but radiator
coolant pours out?!
No other leaks noticed. I read an earlier post about bleeding thermostat ?
Again prior to installing new coolant and thermostat I had No Problems!
Thank you in advance for any help..
