so this morning i went out and started the K5 and the heater seemed dead? i was in a hurry, so i just got done looking at it. seems all the wiring, connections, etc are good. took the dash apart and checked the controls on the back of the actual unit thats mounted in the dash. couldnt find anything wrong there? then i noticed that some fluid, looks like coolant is leaking underneath the glove box? what in the hell is that? and could this be the reason my heater is not working? heater core maybe? help CK5, its cold at 4am when i go to work and i need my heat.. :wink1:
 
you guys are freaking awesome. withing the first paragraph it told me exactley what was happening to me. so is there anyway to get it to stop leaking before i replace it? i wont be able to do it untill late afternoon tomorrow or saturday, and i dont want coolant leaking all over the inside of the k5?
 
You can bypass the coolant lines that enter into the cab in the firewall. Just look at the hoses and you will see what I am talking about.

i see.. maybe i can do that before work or something, or just suck it up, cuz its not leakin that bad..

thanks again guys, u guys are a life save :bow:
 
The heater core blew out on my 83 1/2 ton. It's been relegated to farm truck status and only gets driven in the summer. Instead of replacing the heater core I bought a 5/8 x 3/4(I think those are the hose sizes:dunno:) brass insert and a couple of hose clamps and used it to loop the hoses together. Problem solved........
 
well if the whole process of swapping out the heater core is as easy as the write up says, i think i will make it a saturday project this coming wknd. i know my dads 81 chevy is doing the same thing. i'll do it this weekend and see if it really is as easy as they say? :wink1:
 
I changed mine out about 2 years ago and had little problems. I would allot about 2-3 hours. At least thats how long it took me. I was being real careful with all the linkage and cleaned out all the vent tubes while I was in there.
