I've read some other posts but nothing on this year model.

I am not getting any heat. When the engine is hot, the hose coming from the top of the engine to radiator is hot. You can squeeze it so it isn't clogged and the thermostat isn't messing up or sealed shut.

The lower hose from the radiator to engine isn't hot but is warm.

The 2 hoses for the heater core are hot.

When I give it gas, you can feel some warmth.

But it isn't like it was when I bought it. Lol

I need help lol And is there any other advice to my vehicle that I can offer?

Hi JustinJones and TY for the donation

Check and test the thermostat if okay-radiator could be clogged, heater core too, and water pump not doing its job circulating coolant thruout the engine

Step 1 - A heater cannot operate unless the engine is full of coolant/antifreeze. If coolant level is low check the system for leaks.
