Hello,
So, the engine is all back together.
For the initial start-up I did the Subaru Relearn after a long time without a battery. I didn't touch the accelerator pedal during initial start, and let it idle for at least 40 minutes.
During this time I had Lisle 24680 Spill-Free Funnel attached to the Radiator Filler port, and the front end of the car was elevated and up on jack stand to help trapped air bubbles from the system for the first 30 minutes.
So, I was letting the car idle for a long time, when I noticed the Temperature Gauge was climbing up towards HOT area on the gauge. I did not let it get there though. FYI, both fans are running the way there are supposed to. The Anti-Freeze in Subaru brand for my year of car.
After I turned the car off for a few minutes the temp came back to normal (Gauge was like just below the 9 'o'clock position)
Is this a air bubble that is trapped or maybe a bad thermostat?
Thoughts?
