If what you need to do is replace the heater core, then this is a very hard job. I just did one on a 5.0 V-8 Explorer and it was a nightmare. Since you don't mention heater core replacement I'll assume you want to remove the plenum box for another reason.

To remove the plenum box you will have to remove the steering wheel and unbolt the column from the dash and disconnect the shifter cable, it will then hang down. After that you will find two large bolts at either end of the dash after it curves downward on each end. There are also large bolts running across the top of the dash, probably two on the left above the instrument cluster and two on the right above the glove box. Plus one or two more in the center. All these are under the molding that should just pop out. You will also find a long bracket and bolt under the dash to the left of the glove box and a smaller one on the drivers side which have to be removed. And this is just the big stuff, there are several small lines,cables,nuts, clips and vacumn lines that will have to be removed once the dash is lose. Also to completely remove the plenum box the main wiring harness will have to be disconnected and partially or totally removed as well. If what you're trying to do is replace the heater core then you'll also have to disconnect the air conditioner lines and remove the underhood plenum box as well. This is an extremely hard job especially if you have a V-8, don't try this job at home without experienced help. I did this in a 96 model and there are small changes from year to year but all Explorer's are basically the same. This is one job worth paying for, Good Luck!!

Do you have to pull dash to replace heater core on a 1987 grand marquis?

The good folks at Chilton say no you remove the plenum from under the dash and then remove the heater core from the plenum. You may want to get the book for this one as they're are about twenty steps (many things to remove) before the plenum will come out. Good luck.

How to change heater hose 96 Isuzu Rodeo?

Changing the heater hose hidden between the engine and the firewall under the plenum on a 96 isuzu rodeo. Best option since there is limited access is to remove the plenum. Take all the bolts out of plenum. Remove wire harness to free plenum up enough to remove. Detach from air intake. Then you'll be able to get at that hose. When putting it back on you'll need a new plenum gasket. Hose cost around $10 and gasket is like $6. Garage will probably charge you $300+


When replacing a heater core on a 1999 Mercury Grand Marquis Does it require the removal of the dash?

Yes, kinda. The correct way is to remove the dash because you need to remove the AC box to access the heater core. I had a mechanic that partially removed the dash and held it out of the way with a piece of 2x4 lumber which eliminated the need to remove the whole thing Yes,but dont be intimidated because I will tell you a shortcut! After bending and prying on the plenum I realized about this great ford motor conspiracy! It goes like this,Dont give any info on how you only have to loosen the dash and pull it out 6 inches and then remove 4 bolts on the passenger top part of plenum and pull up on the heater core. Autozones info and repair site does not tell you this.When looking at the plenum and ducts it makes you think that the heater core is deep inside the plenum and it's not. I pulled the dash out completely and this was a waste of time as I also removed the plenum completely.Then I took the heater core out of the pasenger top side of the plenum. So now I have 78 nuts and bolts in a can and I have a 6 hour project on my hands which involves a dash,steering wheel,and plenum as chiltons and autozone directed down a much longer path than I needed to take.

How do you replace a heater hose on a 1965 ford mustang?

First you need to drain the coolant enough so there's no coolant in the heater lines. Then you have to go under the dash and open up the heater plenum (the black box) and disconnect whatever heater tube you are replacing form the heater core. Lastly, remove the other end of the heater tube from the water pump/intake and pull it through the firewall. Install is the same but in reverse.
