2003 Silverado 5.3 heater core install
I am having heating issues - not very hot, thinking about flushing system first but wanted to know if anyone is having similar problems on a 2003 model - 110k miles, and should I be looking at replacing the core. I smelled fluid once last week for first time and have not checked hoses to see if one's hot and the other is cold as of yet.

Heater Core install
Thanks - I already flushed the system, replaced hoses & thermostat last summer, but in Phoenix - we do not need the heat as much - and just now starting to see a problem.
