Car started running hot all of a sudden, 4 days ago. Check engine light came on with code for "improper coolant flow". Replaced t-stat/housing with GM part from dealer. Warmed car up then drove approx 5 miles temp held steady. Parked car for approx 2hrs then left to go to town, immediately started running hot-cold-hot and has no power at take-off. RPMs climb but car barely goes, got worse the more I drove. Feels like converter stopped up but plenty of exhaust coming out. Boiling coolant within 2 miles from home.
