Compatible Models

We do our best to list all compatible models. Although this may be the part you need, your exact model may not appear below.

Compatible equipment / model
  • Buick Enclave 3.6L 2008-2017
  • Chevrolet Traverse 3.6L 2009-2017
  • GMC Acadia 3.6L 2007-2017
  • Saturn Outlook 3.6L 2007-2010

Product Overview

A sweet coolant smell, damp firewall area, low reservoir, or steam from a split quick-connect hose can turn into an overheat quickly. This set replaces the heater-circuit inlet and outlet lines on the listed Lambda-platform 3.6L vehicles.

The old 2007-2017 blanket range was too loose: Enclave begins in 2008, Traverse in 2009, Acadia in 2007, and Outlook ends in 2010. Rear auxiliary HVAC, routing clips, quick-connect styles, and production changes can still affect the hose set, so compare every branch and fitting.

Key Features & Performance

  • Heater-circuit inlet and outlet hose set
  • Molded routing for compatible 3.6L crossover applications
  • Quick-connect and branch details must match
  • Replacement for swollen, split, or leaking hose assemblies
  • Includes the paired lines shown rather than a single short hose

Replaces Part Numbers

  • 20765678
  • 25862088

Common Uses

  • Repairing coolant leakage near heater-hose fittings

Installation & Fitment

  • Inspect heater-core tubes for corrosion before forcing connectors
  • Replace retaining clips or seals that are distorted
  • Refill with the correct coolant, bleed air, run the heater, and inspect every joint under pressure

Compatibility Notice

Northline Parts does its best to list all known compatible models, but the correct part may fit an application not shown.

Model, production date, serial number, engine or equipment configuration, installed options, and previous repairs can affect fitment. Compare the original part, identifying numbers, dimensions, connections, and mounting details before purchase.

Frequently Asked Questions

Q: Can a heater hose leak cause engine overheating? A: Yes. Coolant loss and trapped air can reduce circulation and quickly raise engine temperature.

Q: Why are the model years different by vehicle? A: These related crossovers launched in different years; the corrected list reflects each model's actual range.

Q: Does the set fit vehicles with rear heat? A: Routing can differ with auxiliary HVAC. Compare branches and fittings to the original hoses.

Q: Should the heater core be replaced too? A: Only if it leaks or is restricted. Inspect the tubes carefully while the hoses are removed.
