Do I need to drain cooling system?
Simply draining the radiator may get rid of most of the old antifreeze but could leave some coolant and contaminants behind, which would then mix with and pollute your new antifreeze and cause overheating. If you flush the radiator but ignore any leaks, your engine is likely to overheat again shortly after the flush.
Where is the drain valve on a radiator?
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.
What happens if you don’t drain your coolant?
If you use only water without coolant, your hoses and pipes will eventually rust, leading to bigger problems like leaks or system malfunction. Coolant, also known as anti-freeze, protects your cooling system while aiding the water in absorbing heat from the engine.
How do you bleed an old radiator without a valve?

- Check the pressure gauge on the boiler.
Can coolant last 10 years?

Where is the best place to place a drain valve?

Can a drain valve be added to a pump?
If not, be prepared for different kinds of acrobatics and case juggling to get most of the liquid out. In this case, pun intended, a drain port added next to the pump reservoir combo unit would be a neat option.
