Question about 1992 Cadillac DeVille

92 deville, plastic T-shaped piece

There's a t-shaped black plastic pipe that connects several coolant hoses up near the firewall under the hood. Mine broke and now I can't drive because the coolant's pouring out on the ground. 
Does anyone know what that piece is called so I can order another one? And do you know who would have it?!
Thank you-

    Thanks. But do you think an auto parts store like autozone or another might also have this part? The dealer is very expensive on parts.

    Thanks--I went to the junkyard and pulled one. Such a little piece they let me have it for free.

I had the same problem, the Cadillac dealer told me the part was discontinued, really this is a specific looking part, it has two different diameters to divert coolant flow. In any event, I was unable to get the part from Advance Auto, but a smaller auto parts store carried a T valve (same outer diameter) where all three inner inlets/outlets were the same diameter. Since I didn't think I could find another suitable replacement I used it. I as of yet see no harm heating or otherwise.

List price should be around $13.00 but you could use a generic napa tee to get by in a pinch. The factory part has a reduced hole in it, where as the generic napa parts won't. I am not sure why there is a restrictor orfice in the left side, but used parts will not help you here. The plastic gets brittle from heat and age so please replace this with new. Also have your hoses checked once a year for wear and tear. They do not last a life time. heat and pressure deteriorates them from the inside out, so the will look good on the outside when the get bad on the inside.

Can I get a how-to on replacing the heater core in a 1997 Cadillac deville d'elegance?

It could be difficult, but I'll tell you some of the basic steps. Remove the 2 hoses going to the heater core, they are under the hood, more toward the passenger side back on the firewall, they attach to the heater core right there, pay attention to where each hose goes. You might need a special tool to remove those hoses due to the funny fitting they have on them. What I've done is cut them off and just use regular hose clamps on the hoses later. Now the fun part. Remove the plastic trim under the dash on the passenger's side, remove your glove box if you can to have better access. The heater core is inside a plastic cover, looks like a box, you need to remove the screws and take it apart to get to the heater core. Remove the heater core. Installation is reversed to removal. Do not put all the plastic pieces back till you are sure there is no leaks. Reattach your hoses and check your coolant level. Turn heat on and check for leaks, replace plastic trim and glove box. Done!!

How To Replace A Heater Core 1995 Olds Aurora

Start inside the vehicle on the drivers side, remove the drivers side bottom dashboard plastic panels, you'll need to pop out the switches on either side of the steering column to access the 10mm bolts that hold the plastic panel, and steel panel under it. Working directly in front of the console above the floor, by the firewall, will be a black plastic cover on top of another black plastic cover. They are held in by 5.5 mm screws. Once both panels are removed, you will finally see the heater core. There are 2 straps that hold the heater core in place. Remove the 5.5 mm screws that hold the straps to the housing. Now, from under the hood, around the center of the firewall, there will be a rectanglar shaped vacuum box mounted on top of a relay bracket, remove to 3 10mm nuts to move vacuum box and relay bracket out of the way to access the heater core hoses. It may help to, from the inside, push the heater core forward thru the firewall, and then from under the hood, cut the aluminum tubes a inch or so from the heater hoses, a long sharp edge flat blade screwdriver might help. You can do this from inside the car, but watch for anti freeze. Remove the hog ring clamps, vice grips might help, in removing them. Use alot of WD-40, by spraying between the hose and the tubing, use a thin screwdriver between the hose and tubing to break the seal of the rubber hose to the tubing. Remove the 2 tubing pieces from the heater hoses. You are ready to reassemble. I'd replace the clamps with some worm gear clamps, alot easier to deal with.

Short hose leaking coolant/water in engine at firewall

The only coolant hoses i know of that would be anywhere near there would be ran to your heater core. Try looking for a place to reconnect the hose to. The heater uses your coolant to heat your vehicle & it sounds like the hose came off.

My 93 saab 900s only has third and fourth gears.

I know exactly what happened. Look at the shifter linkage at the transmission. It's under the hood, close to the firewall, directly forward of the shifter knob. There's a black plastic bushing or connecting piece which broke and became separated from a 5-6mm diameter steel rod. You will see it clearly if you look under the hood while someone else moves the shifter knob around from inside the car. Buy a small metal hose clamp (~1 inch diameter or less, coolant hose clamp, same size as the clamp on the coolant reservoir). Slide it over the steel rod, push the rod back into the broken plastic piece firmly, and slide the clamp over the broken plastic part, and tighten it up. You should have all 5 gears back. It happened to my 1997 900SE, and this improvised repair has been holding up fine for two years now. Good Luck.

How do I replace the cabin air filter?

Open the hood and look at the passenger side near the firewall. Remove the black plastic piece near the windshield. It has a few clips that can be pried off with a flat screw driver. Remove the two phillips screws and pull out the second plastic shield. The air filter is triangular in shape and fits into a space in the corner. Replace the filter and then put the two shields back on.
The filter is located under the hood, just in front of the windshield on the passenger side under the cowl grille.
Hope this helps

Heater core replacement 1998 buick skylark

LOCATION: You will find it inside the car , under the dash . Excuse me, in the CENTER of the car right above the Transmission tunnel.

Take the ashtray assembly out and remove the Glove Box and you will see a Black Plastic Box containing the Heater core. You may have to take apart the Lower dash on the Passenger Side. You will need a piece of pipe about 2" to 3"long that will fit inside the diameter of the two heater hoses at the firewall and two hose clamps.
  1. disconnect the two hoses at the firewall;
  2. slip a clamp on each hose;
  3. slip the piece of pipe into both hose ends to connect the two hoses together;
  4. install and tighten clamps on each end of hoses over pipe. (You might want to put a little grease on the pipe for easier removal when you are ready to install new core.)
  5. Start engine and check for leaks at the connections.

Does my 92 deville have coolant bypass hose?

Yes, it is on the back or the engine near the firewall.

Drain the coolant. Remove the dashboard first, then a bunch of air ducts, then the heater core cover. Remove the heater hoses in the rear of the motor, and finally the heater core.
