Where is the radiator drain cap?

A radiator drain petcock is usually located above the bottom of the radiator. So even if you can open it, you're not draining the radiator completely. That's why shops always remove the lower radiator hose. That drains the entire radiator AND most of the coolant from the engine.

Where is the Petcock located?

Petcock valves may be installed inside a carburetor. Fuel petcocks install in an accessible location of a gravity-fed fuel system. Gravity fed fuel systems do not use fuel pumps, and theses petcocks have three positions. The positions determine the flow of the fuel through the system.

What is the radiator cap?

A radiator cap keeps the cooling system pressured which raises the boiling point. ... The radiator cap also has a vacuum valve that allows coolant to flow from the reservoir tank to the radiator during cool down. When the coolant temperature drops, the coolant will contract and create a vacuum.
