ok i did a search and have read up on this alot but i have not found any pictures. can someone please post me a picture of the hoses that go into the heater core so i know what i am looking for. i have an 02 blazer with the 4.3. i am not very mechanically inclined so sorry if this is dumb but i really dont know what i am looking for to see if both hoses are warm.
thanks for the help.

*hey richard why cant i upload photos?

 

Dunno, can't see from here what you're doing.

Are you tying to upload from your computer or download from a picture hosting site?

 

just plain old copy & paste. i use to use the other picture uploading site. i forgot what it was called. i dont think that works anymore either

 

ok its dark out now but i will check those tomorrow thanks for the pictures that will help a lot.

 

if you end up flushing, make sure you flush it both ways. and make sure you top off your coolant when your done. also helps to run your heat on full blast before you flush to circulate what you can through the core. then have your truck shut down when you do flush it. then after you get everything hooked back up crank the heat back on and see if you get any heat. wouldn't hurt to do a system flush radiator and all in the summer. thats what im plannin. i know peak makes a super cleaner you mix with plain water after you drain the coolant. i dont have the guts to do it now it below freezing temps. i'd be worried it freeze.
