iKer Engine Heater Hose Set for Buick Enclave GMC Acadia Chevrolet Traverse 2007-2017 — PA66 T-connectors, Reinforced Rubber

iKer Engine Heater Hose Set is a direct-replacement heater hose assembly designed to fit Buick Enclave, GMC Acadia, Chevrolet Traverse and Saturn Outlook models from 2007–2017, using OEM-compatible part numbers 20765678, 25862087, 25862088 and 626-562.

This heater hose kit replaces worn or leaking heater lines with a ready-to-install assembly built from PA66 T-shaped connectors and reinforced rubber hose. The assembly is engineered to match factory routing and connection points so you get a snug fit without modification. Because new rubber parts sometimes carry a mild manufacturing odor, simply unpack and ventilate for 24–48 hours before installation.

Will this heater hose set fit my vehicle?

This kit is made to be compatible with a range of GM crossover and SUV models: Buick Enclave (2008–2017), GMC Acadia (2007–2017), Chevrolet Traverse (2009–2017) and Saturn Outlook (2007–2010). Confirm fit by checking your vehicle’s year and matching one of the listed replacement part numbers.

• Compatible models: Enclave 2008–2017, Acadia 2007–2017, Traverse 2009–2017, Outlook 2007–2010
• OEM-equivalent numbers: 20765678, 25862087, 25862088, 626-562
• Designed to match factory hose routing and connector locations

What materials and construction does the hose set use?

The assembly uses PA66 (glass-reinforced nylon) T-shaped connectors joined to reinforced rubber hoses for a balance of strength and flexibility. Connectors resist heat and chemical exposure while the hose material handles coolant pressure and flexing under engine movement.

• PA66 T-shaped connectors for chemical and temperature resistance
• Durable rubber hose reinforced for pressure and longevity
• Factory-style fittings to minimize leaks and simplify installation

How difficult is installation and what should I expect?

Installation is intended as a direct replacement: the hose set is built to the same connection points and routing as the original unit so no cutting, splicing, or extra adapters are required in most cases. Basic hand tools and common mechanical experience are typically enough to complete the swap; allow time to drain coolant and properly refill and bleed the system after fitting.

• Direct-replace design—no custom modification typically required
• Requires coolant drain, fitting of hoses, and system bleeding afterward
• Basic tools and mechanical familiarity recommended for safe installation

Is there any new-part odor or break-in I should know about?

New rubber and plastic components often carry a mild manufacturing smell from protective treatments or packaging. This is normal and dissipates quickly if the parts are unpacked and aired for a day or two before installation. If the odor persists after installation, ensure the vehicle is ventilated while first heating systems are used.

• Minor packaging/manufacturing odor may be present on arrival
• Air out unpacked parts for 24–48 hours to reduce smell
• Odor is temporary and not an indicator of defective parts

Who this is for: Drivers and DIY mechanics who own compatible Buick, GMC, Chevrolet or Saturn crossovers and need a dependable, OEM-compatible heater hose replacement. This kit suits vehicles with leaking, cracked or aged heater hoses where a direct swap is preferred to restore coolant routing without custom fabrication. iKer provides support and aims for customer satisfaction with each replacement assembly.
