[Help] Replaced Coolant Expansion. Still Overheating

I had a leak coming from the coolant expansions which is why I thought that the car was overheating, so I replaced it. Now its still overheating after ive filled it back up. What else could it be? Do I need to bleed the system?

Perhaps you have air, if you don't see any coolant leaking...

Pour coolant in until it overflows.

Keep pouring until the coolant is bubble-free (this may take a minute or two).
You will spill a lot of coolant.
Top up ET.
Use turkey baster to remove excess coolant in the ET.
Reinstall bleeder screw and ET cap.
Drive to verify temps are stable and heat comes out of the vents.

Check frequently over the next few days and top off as necessary.

Is your electric fan spinning fast when your car is starting to overheat???? Should be at max speed.

Glad it worked out okay. Just make sure to monitor the coolant level, and the temp gauge, for the next week.
