Did a drain and refill on the radiator last night. Opened the bleed screw until I saw coolant. Let the motor run (I have a lisle funnel) until the tstat opened and it pretty much stopped burping. The heat took a bit longer than usual to get hot. What’s got me a bit worried is that once I press the accelerator, the heat gets scolding hot. Once I let go, it goes back to “very warm/hot”. Is this normal or indicative of an air bubble? I’ve got through about 3-4 warm-up/cool down cycles and the level of coolant in the overflow hasn’t changed.
I can try opening the bleed screw again but wouldn’t that not do anything if the air bubble is possibly in the heater core? If I should re-open the bleeder, what is the procedure? (radiator cap off, drain the overflow, etc). Thanks in advance.
