There is a removal tool to release plastic locking tabs at back near fire wall, I had the same problem with my 01 silverado I used a 4" piece of hacksaw blade held with vice grips and cut aluminum cover and pried it apart to release, be careful not to cut heater core tube.

Used Dremel Multimax (a vibrating saw tip) to "chisel off" from the tip to where I could pry off the quick connect ears from the metal tube tip of the heater core. The new plastic connector piece was around $10.

Had to put the quick connect in first. Using some vaseline and pounding it in gently with a small wooden 2x4 (to reach in) and a hammer, I was able to seat it in firmly. Make sure the new piece actually goes in and cannot be pulled out manually. Then cut off to a new tip of the old hose and connect to the nipple of the new plastic piece.

The plastic piece already has a built-in rubber gasket. You will cut into the old gasket when you try to cut off the old plastic piece. I had heard there is a removal tool for this, but the auto parts dealer said they did not have it. Removal = 30 minutes; Replacement = 5 minutes.

SOURCE: heater hose broke at firewall/hard plastic coupling/how to remove

The plastic extension on the core can be removed, only if you take the core out. It's a factory "heat shrink" deal though and I am not aware of any means of putting one back on.(dealer or radiator shop may know) If you try to run a hose directly from it, likely the clamp would get in the way.If it wasn't so hard to get it out, it would be worth experimenting with.
Good luck

Heater hose connector at firewall is broken


Hi. I just had the same issue on my '99 Silverado last week. There are two connections for the heater hoses to the Heater core. One is white and the other is black. The Black one is available at any autoparts store for about 5 bucks but the white one is a dealer only part that the autoparts store guys will say does not exist. That is the bad news. The good news is that you do not need to use the dealer only part. The black fittings worked just fine for me. You will need to use a fuel line disconnect tool to remove the existing fittings from the heater core. These should run between 10 and 20 bucks for a set. Good luck. Joe

Broken heater hose @ the firewall.


I had this happen on my 99 Sierra 4.8L pickup. The plastic connector deteriorated and broke off in the hose. Not knowing how it worked, I took a hacksaw blade and carefully sliced the outer plastic piece down the side so I could split it apart leaving the metal pipe untouched. (It is made to easily slide on but not come off due to internal one way snaps.) The dealer sold me the new part which was effortless to push on.

99 Chevy Z71 heater core inlet hose male fitting broke


This is an easy $7.00 fix. Go to your local auto parts store and get a GM Heater Hose Fitting. I went to NAPA, part #730-5631. Cut of the old fiting with a hack saw blade, being careful not to damage the pipe from the heater core, put the new one on. Total time takes less than 10 minutes, make sure you fill your coolant resevoir.
