Hello my name is XXXXX XXXXX i will do my best to help you.

 

are the lines to the heater core near the firewall both hot or only one???

does the fan blow strong?

Customer: replied 4 years ago.
Fan is good. The hose from the top of the water pump is not so warm, the other is warm.
Customer: replied 4 years ago.
Clogged core?
Expert:  Lou P. replied 4 years ago.
yes thats what im getting at. the blazers are famous for the DEX-COOL antifreeze to clog the core up. and flushing doesnt help so if the hoses going up to the core are warm or hot and you get no heat output then the core will need to be changed,Lou.

I switched coolants when I bought it 6 years ago, back to the green stuff. Can the flush be a do-it yourself job?
