Has anyone done a write-up on the heater core replacement for the 1999-series Blazers? I have that one staring me in the face. I tried the GM vegetable-based stop leak (comes in six-button pack), but no luck. The core still has a slow leak. I'm considering Bar's but don't wnt to get too carried away with adding gunk to the system.

 

yup, mine was $800, 600 worth of labour [:@] and now he put my dash together all fudged, wires sticken out by the gas pedal, grrrrrr [:'(]

 

Biggreen spake and said "it is finished, thou hast toiled many thine hours to accomplish this noble task.". Argh, not a moment too soon, started pouring down snow as I was hooking up the new hose.

600-800 dollars for a 25 dollar part? How do you sleep at night?>!?

I just did the serpentine belt on my cougar. Im kinda so-so, I think I know more than the average driver, but Im no mechanic. I figured the belt replacement would be a snap But I didnt want to start the serpentine belt then get halfway done and realize I couldn't do it and be stranded. So I called a shop, they told me 40-60 for the belt plus another 30 to install it. I was like "I dont think so". Paid 20 bucks for a belt at autozone and managed to do it without a hitch.

 

was like 200 for a new AC delco core, 600 to put it in. $25 for a heater core assembly with hoses and clamps and such? i wish, and i sleep just fine, thanks

 

25 dollars for the core. .99 cents per foot of hose (bought 7 feet) And 2 dollars for hose clamps.. Yea? Heater cores aren't exactly complex machines. Your truck is a 98? http://www.rockauto.com/catalog/x,ca...,parttype,6864

 

LOL 200 for a core and you think it's worth it because it comes with $9.00 in hoses and clamps? Alls you need is 4-6 clamps depending on if you want to double up clamps on the core side and 3/4" hose I believe.... I think I used 3/4" on one side and 11/16" on the other side.

2nd gen guys, I feel for ya, I read a write-up with pics on 2nd gen....Wow, GM needs to be shot for that one.

 

I think the one hose is 5/8s and the big one was 3/4s.. At least on the 1st gen.

 

We've got it easy compared with Dodge! How would you like to have to disassemble your whole dash AND recover/recharge your A/C whenever something like this happens? LOL

 

Id love to, its sounds like a wonderful afternoon of fun-filled adventure. (sarcasm)

 

I have a 2004 withe the v-6. How hard is it to change the heater core? And what all do you have to go through to get to it?
