[89K1500Chevy]

Anyone replaced there heatercore on there truck? Im doing it to my 85 GMC an before i go pullout everything under the dash I was wondering how easy this is on these style trucks/blazers? It doesnt look like it will be too hard but is there any tricky parts or anything? thanks for any information an help!

its a piece of cake,
remove your glove box door and the box itself and you have access to everything.
i replaced the heater core on my Blazer in about 45min start to finish

Well im halfway done i have everything outta the truck an put the fender back on so i can go get the new heater core from the auto parts store. The Ck5 guide has been very helpful up to this point. Only wished there were more pics. but i got everything out just fine by reading it. took an hour takin my time an using hand tools. i think that now knowing what exactly to pull i could do it in 30mins an be done in 1 hour.
