Honda Civic 2009 making whirling noise then buzz(steam?) after starting and idling
My cars been whirling/rumbling and then letting off steam with a buzz whenever I start it and let it idle or try running it. Has been doing this since last night. No errors on OB sensor, nothing on the dash, Ive replaced the battery(original problem was it wouldnt even start, started doing this after I jumped it) and refilled the antifreeze coolant(Peak Blue for hondas, it was very low before).
Update: It ran perfectly on the way home. Left it for a couple of hours and now it wont start again, dash lights turned on once but now its acting like it drained the completely new battery. Looks like the coolant is critically low again. A friend told me that it looks like the upper condensation hose got out of its housing. TLDR: Refilled coolant, its low again.
