Hi I recently bought an 09 honda civic ex coup and my coolant in my over flow keeps draining somewhere idk if it is in the engine or a leak from a hose it only had 93000 miles on it and was well taken care of it runs at normal temp the exhaust isn’t a bad color and you can only see it when it’s cold. What could be wrong also I ran the Vin and they’re no recalls for the cracked engin block on mine. The engine is 1.8 L 4 cylinder.
Check for external leaks first, radiator, hoses, thermostat housing. If it’s a dry you may have a issue with the head gasket. You can do a combustion gas leak test with a relatively cheap kit.
