I have a 99 honda accord and the heat works a little bit. It blows fine but not very warm. Is there anything I can do to check the heater core and see if it is not blocked. I want to flush the coolant is there a good product to use to flush the systems thank

Hi Jerry,

It is not necessary and I would not recommend any radiator flush if there is coolant in the system now.

When heater is not functioning correctly, you should check the hoses to the heater core and ensure both are hot when in operations.
It could be due to the vacumn solenoid or hoses that are causing the heater valve not to open fully.
