97 Blazer Heater Core Leaking - Pirate4x4.Com : 4x4 and Off-Road Forum

Hello everyone....

After lurking this killer Board for some time I have no choice but to ask a quick question....

The wife's little Blazer sprung a heater core leak...

How are those things to replace? does the dash have to be pulled, or can you sneak behind it and do the swap?

Just wondering if anyone has done one....

Thanx!

if you look into the repair manuals they want you to tear apart you dash to get to it. If it is like my 3/4 ton, you should beable to get it out by just taking the 6 screws holding the lower cover to the heater box (black box looking thing on the Pass side) and taking the core out. Took me an hour to do it. But beware some of those 6 screws are hard to get to.

I am on my 3rd one and the easest way to do it is to pull the dash. It will take about three hrs to do. you also have to drop the sterring colum to.

you need to pull the dash, which realy isn't as bad as it sounds . Pretty straight forward. Have fun. Brett

Well ive got an 89 silverado and ill tell you the truth, theres the six screw way which i opt for because now there are only four back in there(k rigg you know what im talkin about) and the dash way suked for me before i did the six bolt way. look at it and yo decide the six bolt way is way faster, just dont do it after youve been driving for a while
