Thermostat change was done and temps are back to normal.

I unscrewed the coolant drain cap and it is seeping down and not fast enough!!!

I was sold a 80 degree Behr t-stat. While monitoring HVAC at idle the car never goes above 84 degrees.

As a result, the fluid in the coolant expansion tank never really boils to a point where it will seep down into the radiator.

I ran the car with the cap off after putting water in the tank and waiting for it to drain so that I could put the flush solution. Well, the water never gets too hot. After an hour of running, I touched the water and it was tea drinking hot but not boiling.

So I need to figure out where the radiator cap is so that I can clean the tank out and get the radiator flush completed.

Any suggestions? Pics?

TIA!
