Overheating problem
So we have a 2004 crown Victoria LX. For the last couple weeks she’s been running really hot and I’ve had to stick on the heaters to keep her at normal temp. Just replaced the thermostat ,and I replaced the Electric fan a couple months ago. Not loosing coolant. The top hose of my radiator gets up to temp. Any ideas?
Edit: weird thing is, at night it worked fine ,even before I replaced the thermostat. It’s just like it’s too hot or smth idk.
