See my previous posts lol. Long story short, if your car:

1. Doesn’t overheat on the highway/while moving
2. Slowly overheats when idle after driving
3. Has clean oil
4. No white smoke from exhaust
5. No coolant leaks anywhere
6. Heat blows strong
7. All parts of cooling system definitely work

Get a chemical test done on your coolant. In my car there is carbon monoxide leaking from one of the cylinders through the head gasket and into the cooling system 🫠

Figured I’d make this post just in case others have the same issues as me. Without the chemical test I never would’ve known my head gasket was bad. It even passed a compression test just fine.
