Heater core flush???

Hi there,

My 2000 Zr2 was blowing cold air so I figure it was a simple thermostat..Which it was. I shoudlnt have but i did...Bring it to the dealership and they recommended i flush the rad (which i have never done myself)..and flush the heater coil.

Can anyone explain how to flush the heater core on the blazer. I was charged out the wazooo ($400) for the 3 simple fixes. Something like 70 bucks for the parts and the rest in labour.

Its time I start doing this stuff on my own since i have the garage space and will to learn..Thank you

We have an article for that: Heater Core Flush

That and MUCH more found in the Tech Article (DIY) Index.

ahh my bad, sorry I didnt see it. Ill have a look now.. thanks
