I have replaced a lot of parts and done everything possible, but still the heat will not work. Water pump and heater core are brand new , and the thermostat, all the electrical works and I have bled the system many times. One of the heater core hoses doesn’t get hot but the heater core is brand new and isn’t clogged in any way.

Hello,

This sounds like you could possibly have an air pocket in the cooling system not allowing the coolant to flow.In the diagrams down below I have included the diagnostic troubleshooting guide for your vehicle's cooling system. Please go through the guide and get back to us with what you can find out please.

Thanks,
Alex
