My upper coolant hose from the thermostat housing to the engine top leaks a bit when the engine is cold. Not much but too much to not worry
Anyone have an idea or experience how much coolant would rinse out if I remove the thermostat housing without prior coolant drainage?
I also think of sucking out as much fluid as possible through the thermostat thread with a vac pump and a hose and catch the residual with a cloth.
thanks ahead
At some point I did exactly what you have in mind. I figured it couldn't be all that much coolant. After all, the thremostat is pretty high up. It turned out to be a lot more than I anticipated. Put a big tray underneath the car and be prepared for more of a mess than you'd expect. Good luck and cheers,
