Q: Sudden Coolant Leak

asked by on

My car has been running fine and has never overheated. While I was driving the other day, I looked down and it said "coolant low, stop engine". I didn't realize I had a leak until I went to fill the coolant back up and saw it leaking all out from under my car. The whole coolant "tank" empties within a minute. It looks like it's coming from the bottom passenger side of the radiator and I also noticed some coolant dripped all down that side of the radiator as well. Checked the hoses and they seem fine. Tried stop leak and it had seemed to work until I turned the car back off and it all leaked right out. Anyone, please give me any advice you have!

Q: Recommendation on how thick oil to use on a 2004 Corolla

It depends on what shape your engine is in. If you've been using 10-30W and it runs fine and doesn't burn any oil, then just keep using 10-30W. That's perfectly fine. But on the other hand, if it burns oil,...
