Dorman 800-414CD Heater Hose Connector

Replaced this tee along with the other one on my wife's 2011 GMC Yukon XL Denali had developed a slow drip from one of the seals. Not the easiest part to replace, but should only take 30-45 minutes for both if you are prepared. Just have something to pinch the lines and something to catch the coolant that will still leak out of the system. If you do each tee on it's own with pinched lines you can minimize the coolant loss. After looking at other reviews, I rushed into the replacement and broke off the tabs holding the main hose from the thermostat/water pump. This was not a good idea as the larger of the hose connectors could have been reconnected. To quicken the installation, the tabs should only be broken on the smaller branch that goes down to the aluminum lines for the rear heater.

Super product

Perfect fit on Chevy Tahoe

Good product!! Great buy!!

As advertised, worth every penny

Broke this brittle plastic fitting when changing spark plugs and plug wires. Sinking feeling, snap, gurgle, gurgle. I had to remove the fitting to the right of this one in order to remove the broken fitting. Some here say to replace that one also, since it is equally brittle plastic. Good advice, I do not disagree with them, however, in my case I only replaced the broken one. In the pic you will see a clamp on the heater hose, this is due to the end of that hose having a metal fitting on it, (that needs a new plastic adapter) (you will see it) you can buy a new hose and mess around with all that or just cut the metal 'pressed on fitting' and clamp the hose to the fitting. Do that first then connect the left side smaller hose and then push on the main line headed into the firewall. Easy. No Leaks. Check your radiator fluid (caution, not when hot) as you may lose a bit during this replacement process. Go to youtube and evaluate your skill level vs. this job. This thing cost like $9 bucks, give it a try before you pay a shop $150 to replace it.

I had a leak in my coolant line and I tracked it down. I was so relieved it was not the core. The leak was not terrible. I live out in the boonies and it was easier to order the part I needed off Amazon than tracking into town to track one down. The part came pretty quick. Well packaged. Seems to be built with quality materials. It was very easy to install. The price was definitely cheaper that what brick and mortar stores were charging.

I just wrote a review on the other heater hose connector and will say the same thing here, if you are looking at this, you probably just discovered how brittle these become over time. Do yourself a favor and buy BOTH (this one and the Dorman 800-413CD if you have the same vehicle as me) connectors at the same time. I only bought this one, and when I was trying to connect it, I broke the other one. Trust me, the other one is going to be just as brittle as this one so you might as well doo it too. These were a perfect fit for way less than the OEM parts.

Part fit perfectly.

este articulo ajusta a la perfección, es buena compra ya que es una pieza que remplaza la original y no hay fugas de ningún tipo.

Perfect fit for my 2010 Cadillac Escalade heater core hose. You’ll also need to buy another white T-fitting also. Replace both.(inlet and outlet coolant).

BUEN MATERIAL Y EL EXACTO PARA REMPLAZO. TUVE PROBLEMAS CON LA MANGUERA QUE NO TRAJO LOS ENSAMBLES DE PLASTICO Y ORINGS DE PLUG AND PLAY , REUSANDO LOS VIEJITOS. AUNQUE EN LA MANGUERA APARECEN COM SI LOS TRAJESE. POR LO DEMAS BIEN. ESTA OBSERVACION DE LA MANGUERA ME FALTO EN LA RESEÑA DE ESE PRODUCTO. EL CONECTOR ES EL EXACTO

Instalado en GMC Yukon 2007, queda perfecto, buena calidad
