So Here's the deal, My 02 Bravada was running little hot (about 217F), and since the normal operating temp is 190-215 F, I decided to change the thermostat (just being over cautious and little stupid). Anyway, now she runs even hotter (220-223 F) with the new thermostat (Dorman 902-800). After driving for 20 minutes you could hear the coolant bubbling (or boiling), and the lower hose is not even warm. https://photos.app.goo.gl/MQ8bWLeGF5ahP18ZA
- I flushed the coolant and filled it with tap water. Ran it till it reached temp then drained coolant. I did that twice. Then on the final round, radiator was drained and radiator and reservoir were filled with dexcool.
1) Is my thermostat bad? or my temp sensor?
2) How long should the system be "burped" to get all air pockets out?
3) I topped the reservoir when the engine was cold. Is this okay?
4) I also heard ticking noise that comes and goes away. Not sure what that is. https://photos.app.goo.gl/7XuWyDWc8jC3Aptx6
