- Wed Oct 30, 2013 5:43 am #338190 I got a 1992 honda civic hatch and my heater does not blow out as much hot air. They told me I need to flush out my heater core but I really dont know how. Any tips?

- Sat Nov 02, 2013 5:49 pm #338294 ive never done it on a honda, but on my cherokee, i removed the heater hoses and ran straight water through it. in that case it didnt work, i had to end up replacing the heater core.

You will see coolant coming out at first then it will change to just water. Then I remove the upper radiator hose from the radiator itself and repeat the process. I do the same thing for the lower hose. Doing it this way flushes out the radiator, engine block and the heater core. To clean out a majority of the water I blow into the upper and lower radiator hoses either with my mouth or a air compressor if I have one. Then put in a new thermostat and gasket and refill the cooling system with the proper mix. Don't forget to bleed the system though. I do it this way for my civics, my F-150 and my wrx. Works every time.
