Whats up brothers
last thrusday I was checking all my fluids and noticed that my reservoir coolant was almost empty
so past saturday I bought honda oem type 2 coolant and poured on the tank till it reached between the full and low marked so I took a picture
but then just now I noticed it was a little low and took a picture again to see the difference
what do you brothers think ?
Its been like 40 degrees here at nyc. Ive been using the heater a lot this month but this past weekend it hasnt been that cold

Could be just circulating through the heater core and dislodged a few bubbles?

If it continues to drop I would take it in.

Renzo, good chance it's a leak. You added when cold and checked when cold. I live a couple of miles from you and mine has not gone down. Have it checked

Not good Renzo, not good. If you keep filling and it keeps going down, it's not a question of IF you have a leak, but where.

I had something similar last summer. After a lot of back and frustration, the culprit turned out to be my engine was consuming oil. The engine was re-ringed (pistons and rings replaced). So far so good - thankfully it was all done under warranty.

calm down. it's normal. that model does not have common leaks anywhere, if it wasn't wrecked.

what happens is coolant evaporates over time and has to be topped off. most techs ignore it and get the oil change done or w/e. however, it needs to be topped off occasionally.

the 'problem' here is no one topped it off in a long time, most likely, and air then enters the cooling system because the overflow bottle has no coolant, so it sucks in air as the coolant cools.

as you add coolant now the car sucks in coolant next time it cools down and expels air bubbles into the reservoir as it naturally bleeds itself.

so for the next few days after you drive the car, top it off at the max line when the engine is nice and hot. then when it cools down in the morning check it. drive it, and check it hot again and top it off if needed at the max line.

from then on out just check it at every oil change and stay on top of evaporation! lol
