1993 Impreza 2wd 5spd EJ18. 235,000 miles original engine and transnmission. A few ?'s...
I replaced my thermostat O-ring today and applied some sealant to stop a leak that was at the housing (my fault for not doing it right the first time). Pulled it up on some ramps, drained the coolant and replaced the ring, filled it with coolant as much as I could and then started it and let it run at full temp for about 15 minutes or so keeping an eye on the temp gauge. Added coolant, some bubbles came out, added coolant, some bubbles... ya know, the usual cooling system bleeding. Finally it seemingly stopped and I put the cap on and added coolant to the overflow.
Now my cooling fans stay on alot more than they used to. They stayed on pretty much all day today despite it being fairly cool. Did I bump something? Could it overheat without showing up on the gauge? I kept an eagle-eye on the temp gauge and it didn't budge, nor has it ever.
2nd Queston:
While standing outside of the car I heard a loud, high pitched screeching noise. Seemed to be coming from the bellhousing. I pressed on the clutch pedal and it stopped for a few seconds and then came back again. So I just TOUCHED the pedal and it stopped for a few seconds. Revving the engine also stopped the noise. But at idle when the engine is warm it can be heard from the outside, but not from in the cabin.
The throwout bearing only makes noise when the clutch is released, correct?
I will be posting this in the WTB section as well as here. Does anybody have a low mileage 2wd 5spd Impreza transmission for sale? The last time I drained the diff grease it looked like somebody threw a confetti party inside my transmission.
