heat?

[Brixy]

Picked up an 85' CJ7 on the weekend and drove it a couple hours from where I dropped off the car trailer. It is winter in Canada and I coud not understand why I wasn't getting any heat out of the vents. Turns out this Jeep never had the heater hoses connected. They are hanging closed off in the engine compartment. Who knows what is required to get heat for a cooler climate? Anyone with similar experience?

Do you mean that heater core isn't tied into the cooling system? If the latter, a new heater core will run about $35 (USD) plus a few dollars for the hoses. You may also need adapters (different hose size opening at each end).

yep i'm guessing that the heater core was busted and the po didn't bother putting in a new one. you have to take the heater box out from under the dash to put a new one in, there are studs coming through the firewall on the engine side i think theres 4 of em, one behind the valve cover, to the left side of the battery tray and two under the battery tray, remove the nuts from them and that is all that is holding it in. you might need to remove the battery tray to get to the ones under it but that should be easy. you will also have to take the cables loose from the heater box. then you pull it out from under the dash. after that you take the back off of the heater box and drop your new heater core in. when you put it back together make sure all of your air cont. flaps are in their correct positions. after that if you want some real heat go and get you a chevrolet k5 blazer blower motor and put it in before you re-install the box, it'll run you about $20 for the motor.

The blower motor upgrade is well worth the time and expense. See a previous thread: http://www.jeep-cj.com/forums/f7/my-blazer-heater-blower-motor-upgrade-5150/

Although you can access things behind the dash without removing it -- it sure makes it easier (even if you just pull it off just a little bit to get more access).

it makes it easier but once you find all of the mounting locations and how to pop the cables of you can have it out in 20 min with out pulling the dash
