Left bubble in lines.

Squeeze upper hose a few times to burp it--maker sure thermostat not stuck, too. Then, start car, Cold, refill reservoir as it runs. Close it when coolant starts to warm.

Make also sure you didn't leave belt loose.

Why did you replace the water pump?

Hi so did you change the radiator cap as well as it has a spring in it's cap which becomes weak over time.

You may have an airlock in the system after re-filling. Or Was the water Pump the reason for the overheating in the first place?
Thermostat? Blocked Radiator? Cooling fan?

Assuming we had overheating before? Then we either still have another issue or we have failed to purge air out of system or left drive belt too slack.
one needs to check filler cap is OK. This ought to be first thing we replace as cheap and has a huge effect on temps if low spring pressure or seal failing.
is radiator clear? Have any hoses internal restrictions? Blockages etc any leaks on part of system will result in overheating. Is fan operating correctly? Have we checked thermostat is working? Is not blocked ( small vent hole in correct position and clear?)
a systematic check through the basics and eliminating suspect areas can assist. If all mentioned were OK or replaced. Odds are am air lock in system. That has effect of creating hot spots and overheating. A garage can of course check easily enough and save time but at price of course.

Thermostat?
lower hose anti-collapse coil missing?
radiator plugged?

fan thermostat malfunction?
fan malfunction?
radiator cap pressure?

Loose hose clamp, Radiator cap is bad

It's a ford.

Thorg don't caare

Maybe its your coolant temperature sensor. They don't cost much online.
