    I had one leaking on a '86 Blazer and on it you have to remove the dash pad to get to it. It was winter and I haven't a garage so I took it to a Auto Shop to have it done. It's alot more difficult than the older models.

    I changed mine out on my 85' for the first time with the help of the CK5 write up. And I am a novice mechanic. It was pretty easy, one tip, if you have a digital camera take pic's of how the linkage is hooked up. I did not and it took me a while to figure it out /forums/images/graemlins/rolleyes.gif

    Its been a while since I changed mine on the 88, but Ill try to explain it. It was fairly easy. Dont think I removed the dash pad, but it might make it a little easier. I think the glovebox needs to come out too. The cable from the heater control needs to be removed, along with the 2 hoses from the firewall in the engine bay. A few vent tubes might need to be disconnected too. Then, there are like 3 or 4 nuts that hold the heater box onto the firewall. You get to them from the engine bay also. Might be a few inside the cabin too. When the heater box comes out, you should be able to see how the heater core comes out of the box. Its not too labor intensive, might take 2 hours total. Pretty cheap too, new cores are usually less than $30.

    yeah its not hard at all i JUST did mine in 20 minutes


    there are nuts on the moter side of the firewall, pull the hoses and put them up high, pull the glove box out the box will come off under the dash, two 1/4" or 9/32" hex screws and the core comes right out, thats it!
