G25......thanks for the additional suggestions. I was away on work last week. During that time....the wife used the car. She had to add water to the fluid container twice. I bled the system quite a bit prior to my departure....but as I left the next morning I really did not have a chance to drive and observe the car. I am back home now. The heater is working (per my wife....who would have complained had it not). She says the temp has been good as well.....but she claims to get a whiff of anti-freeze when she exits the car.
I just got back home and have the car on now.....checking for leaks. My wife did not notice any puddles....and I am not seeing anything. I do see a couple of areas where there is still anti-freeze/water from last week, just small pockets away from any tubing that has to do with the cooling system on the car. I really dumped a lot of coolant last week, so my guess is this is leftover smell.
This is what I recall doing. I have never put any tabs or anything into the coolant system, but have used the radiator flush the week prior. This time I used only water. I tried to flush only the radiator, but as the bottom drain was not working, I ended up spraying water into where the radiator cap is, then watching it run out the top hose (disconnected) and let it run until brown stopped and just water came out. Then I took off the thermostat, and started the car and again put water into the radiator....this time the brown crap came out the thermostat hole. Again let that run until I saw water (not that long). I then drained what I could of the water in the radiator by disconnecting the 2 hoses....and after reconnecting the hoses I added Dex. I initially performed the bleed by squeezing the hoses, with the radiator cap off...and kept adding fluid. Then I started to use the drain on the thermostat. At the end, the hoses were no longer collapsing as they had before. But it still did not seem like it was acting normal. But apparently during the week the car ran normally.
I did not know about resetting the coolant temp sensor by unhooking battery, will do today. Also, I think you are correct about the radiator being clogged, and think I will end up replacing that as well.
Thanks again for the suggestions....
