Hi, I have a 98 Honda Accord at about 77k miles. About a month ago when I changed a light bulb, I realized that the coolant reservoir was empty. I never paid attention to the bottle before because I assume the guy who change my engine oil should fill it up. The engine temp is pretty steady, no overheat at all and I do not see any white smoke from exhaust. So I fill it up to max. About two week later, the coolant drop to min line. So I fill it up again. Ever since I start to realize the coolant level in the bottle decrease slowly since I check it in the morning when the engine is cold.
So I went to car shop and they did a pressure check and told me the uppper hose is leaking. So I had them replece both upper hose and lower hose, flush the coolant. Yesterday morning when the engine is cold, I fill up the bottle to max. This morning I saw bottle lever went down again.
Can someone tell me if there are problems here? I appreciate your help.
Thanks a lot
