Heater Core.
 

It's been leaking all summer.. Just got a new one.. Where the hell does it go?

behind the dash....have fun with that

Yeah, that's an understatement Mr. Glue :w2:

To the OP, get a manual for your pickup and plan on spending all day. Helps to have a friend to supply beer, tools while you're hands are full (with said beer and pieces of your truck you never would have dreamed could/would come out) and an extra set of hands.

Your forum name is going to become alot more meaning when you attempt this... Good luck... Done one and never want to really go there ever again

It does suck. Pull the dash apart, lower the steering column, pull the entire dash out, pull the main HVAC system out, all to gain access to the heater core. Oh, drain the coolant and evacuate the A/C before pulling it out.

i kinda enjoy doin it! a lotta takin apart but its all fairly simple! good luck and dont rush

You have GOT to be kidding!
That's just great.. lol
Ohwell I'll give it a whirl.. Might be driving something else for awhile from the sounds of it..

You can get it done in a day but you probably won't get much else done. :c:

It can be done in a day, I have done it myself. Including removing the radiator and washing it out. Stay dedicated to it, and start at a decent time. :c:

Quick way kinda. This is the way I have done 3 of them. Not fun by all means.
