HI Guys
can someone please show a picture where i can fine heater core hoses in and out.
i am looking to flush heater core on 2004 maxima.
whats the procedure to flush heater core.
thanks

 

If you look under the air filter intake tube you'll see two rubber hoses going to the firewall. Remove both of them on the engine side. Use a garden hose to flush not air. With your water on low put the hose on either side of the heater core and watch what comes out. Hopefully you will see some brown ish colored crud coming out. Flush both sides till the water is clear. Put it back together and begin filling the radiator. Probably have to burp the system several times and your done.
