Today I decided the flush my 2011 ES 350, 58K miles and replace it with fresh Asian red from Walmart. Here is what I did:
1. Drained the coolant by opening the valve under the radiator.
2. While draining I started the engine with heat on full blast till the radiator fan kicked in.
3. It was blowing cool air although the temp was set to 85/high.
3. It took a while but was able to drain the whole thing.
4. Flushed it with 2 gallons of distilled water using step 2
5. I started filling with fresh coolant- again using step 2. It took forever. At this point
I suspect air in the system. I located and unscrewed the bleed off valve just enough for air to escape.
6. I was able to fill it with just 1 gallon- the car requires 2.37 gallons.
7. I let it sit for a while and tried to refill with no luck. I could see fluid/air coming out of the bleed off valve.
Note: I heard an intermittent squeaking sound while i had the engine on filling with fresh coolant. The noise subsequently vanished
I took the car for a spin and the temp gauge was in its usual position- almost center. Everything looks normal, the AC heat was behaving accordingly.
What am I doing wrong? Is there something I am missing?
Thanks.
