I replaced my coupler after new O-Rings from the dealer leaked--you need just the right number of O-rings AND SPACERS in place on each hole / line to get things to work properly without leaking--and this part has all of them already installed. Note that you do not have to remove the air handler to get this part out. Somebody else below mentioned using a sharp knife to cut the foam material lining the inside of the firewall--I didn't even have to do that. I removed the accelerator/gas pedal with a 10mm deep socket (three bolts), and then the plate under that (two bolts), as well as the cover in the engine compartment on the firewall, and I was able to remove the entire coupler from inside the car by pulling it down and to the left. It will want to hang up on the foam, but push the foam back with your hand and the part will pop out. Installation is the reverse motion, and easier than removal. When assembling, if you remove the o-rings and spacers, make sure you keep them all together in the same order (stack them!) and get them on the pipe ends in that order too. A touch of vaseline on the pipes will help the o-rings stay on and also seal/slide in without pinching the o-rings. NO LEAKS! Thanks FCP Euro for a great (and affordable) part!

Kit comes with all o rings required. No point replacing the little clips and o rings if you have a leak, might as well as pay a little more but peace of mind down the road!
Don't mess around with the stand-alone clip and o-ring kits. Just buy this coupling kit, which includes everything you need for an easy install. One tip: When you're trying to remove or install the coupling, it seems like it will never fit. I've seen people post pics on websites showing how they cut away part of the coupling to fit it behind the evaporator housing. None of that is necessary. The cutout recess on the cabin side of the firewall is actually foam rubber bonded to a sheet of hard plastic. Take a sharp utility knife and trim away part of the foam and bonded plastic on the left side of the cutout. The coupling will slip in easily. Another tip: If you happen to have some, ahem, personal lubricant handy, it makes the perfect assembly lube for the o-rings. Super slick, light, and water soluble. Polish the metal pipe ends with fine steel wool, apply a small bit of lube, and the pieces will slip together like magic.
Heaters cores SUCK to do. So do yourself a favor and if you're replacing the heater core get this too. TRUST ME. you dont want to have to go back a second time.
Broke the factory firewall pass-through when I was replacing my heater core last time and it put a halt to the repair. I recommend purchasing one of these when you do a heater core replacement if your 850 has high miles, because chances are yours might crack when you remove the hoses!
Learn from my mistake... Order this with the outside heater core hoses, or your heater core. Takes a little longer to get this in but you old coupling WILL break. Great quality, and perfect fitment!
