HELP! Replaced Radiator and Thermo, now engine smoking!
Hey all. Just replaced my leaking radiator and hoses. I also found that the prior owner had taken out the thermostat. I put in a new thermostat (190 degree) and gasket. Flushed the system with distilled water. Refilled with new coolant/water.
I started it and was letting it run to circulate the coolant/water. After about 5 minutes it started squealing. Couldn't tell where the sound was coming from, but it didn't sound like the fan/steering belts. I shut it off and it was smoking.
Side note, it leaks oil- not a lot but some. I (dumbly) just added half a quart of oil without first checking the dipstick. After the squealing and me shutting off the engine, I opened the oil fill knob and smoke came out (some, not a ton).
1. What could the squealing be?
2. Could the smoke be from over filling with oil?
I don't want to run it right now. The temp gauge on the inside doesn't work, so I have no way to know if the engine was overheating.
