How do you bleed the cooling system of a 1988 acura legend? Is there a bleeding screw and where is it located?
Bleed the brakes. It sounds like you have air in the system.
If the cooling system is in good working order the system will bleed the air out itself. If the system has a leak anywhere no matter how small the system will never bleed the air out.
If you see bleeder valves on the cooling system use them to bleed the system. Otherwise, remove the radiator cap, turn the heater control to hot, start the engine, keep the coolant topped off, and watch until no more air bubbles are escaping.
there should be a air valve on the engine that you can bleed the bubbles out of the cooling system.
