Dorman 626-663 Engine Heater Hose Assembly - Aluminum T-Connector Replacement

About This Product

Dealing with heater issues in your GM minivan? This Dorman heater hose assembly is probably your fix! The part number 626-663 replaces the original equipment hose that's known for failing at the plastic T-connector. Dorman's smart upgrade uses an aluminum T-connector instead, which won't crack like the original plastic one did. It fits specific Buick Terraza, Chevrolet Uplander, Pontiac Montana, and Saturn Relay models from the mid-2000s - definitely check your exact vehicle compatibility before ordering. The assembly comes complete with all necessary hoses and clamps, making installation much easier than piecing together individual components. The quality is exactly what you'd expect from Dorman - well-made, proper fitment, and designed to last longer than the original part. If you're losing coolant, noticing heater performance issues, or seeing cracks in your current hose assembly, this replacement will get your heating system back in proper working order. Installation is manageable for most DIYers with basic mechanical skills, though having some experience with cooling system work definitely helps. For the price, it's way cheaper than dealership parts and should prevent the same failure from happening again. If your vehicle's on the compatibility list and you're experiencing heater problems, this upgraded hose assembly is definitely worth considering as your solution!
