Well the heater core finally went. I have to replace it now. Does anyone have a write up for it, or is the haynes manual pretty good on replacing it? Its a 97 Blazer 4X4 4.3. Just replaced the intake gaskets. Thanks and hope to hear from someone.

Here ya go:

heater core

That has the procedure, but is alittle lite on pictures. Also has some good advice.

 

Ok well I got it out. The parts store delivered the wrong one, otherwise I would have it at least in (the heater core) Hopefully the dash goes in smooth like it came out. Lots of stuff to disconnect. But other than that. Not to terribly bad. Thanks swartllk for the write up. Really didn't use it too much and the Haynes manual is very very vague on describing. The don't say you need to disconnect some vacuum lines amongst other things or I just read over it on accident. You can click here for pics. http://s101.photobucket.com/albums/m...r/97%20Blazer/
