I recently replaced the heater hose which had a hole in it, spraying coolant/smoking. A couple weeks after changing these hose i noticed a significant loss in coolant and leaking but no smoke this time. Heat is working fine, i dont smell coolant, and no oil mixture involved. Also, i’ve recently opened up the valve cover without replacing the gasket, grommets and spark plug seals, which im lead to believe is causing an oil leak from under the valve cover (correct me if im wrong) and oil in all of the spark plug holes. YOUR HELP WILL BE GREATLY APPRECIATED!!! THANKS
Can you see where it is leaking from or no? If you have an air bubble in the line anywhere it will discharge coolant from your overflow bottle. Same if your thermostat is stuck. Try wrapping a towel around the hose thats coming out of the bottle and pointed toward the ground and taking the car for a drive. If it is covered in coolant than thats where it is going and you need to burp the system or change thermostat.
is it overheating?
and yes, if you removed the valve cover, and the gasket/grommets are old/hard, it will leak
have you done a cooling system combustion test?
see youtube link
no, it isnt overheating, just leaking
i really can not tell where it is coming from. ive got a failsafe thermostat, meaning it’ll stay stuck open rather than stuck closed to prevent overheating… could that be the cause of leaking?
The most common place for coolant leaks in older Honda/Acura ar at the top and/or bottom caps of the radiator, where the metal is “crimped” over the plastic end caps, [top/bottom caps].
A good way to locate engine leaks, [any kind] is to clean the engine/engine bay real good, [degrease] and dry it using compressed air, then drive the car a few miles and pop the hood, any leaks will show up easly on the clean engine and engine bay.
You can also get fluorescent dyes that can be added to any fluid in the car and then a “black light” can be used to locate the leaks. 94
