GMC Acadia (2007-2017) Radiator Coolant Hose: A Mechanic's Guide
Everything you need to know about replacing the radiator hoses on your first-generation GMC Acadia.
- A leaking radiator hose is a serious issue; do not drive an overheating vehicle.
- Replace radiator hoses in pairs (both upper and lower) for preventative maintenance.
- Always use orange Dex-Cool specification coolant to prevent system damage.
- High-quality aftermarket brands like Gates, Continental, and Dayco offer reliable performance for less than OEM parts.
Signs of a Failing Radiator Hose
A failed radiator hose is a common problem that can leave you stranded. Because they are made of rubber, hoses degrade over time from constant heat and pressure. Watch for these clear warning signs that a hose is about to fail or is already leaking.
- Coolant Leaks: Puddles of orange-colored fluid under the front of your Acadia are a tell-tale sign. This is likely Dex-Cool, the specified coolant for your vehicle, and it has a distinct sweet smell. Leaks often start as small drips from where the hose connects to the radiator or engine.
- Engine Overheating: If your temperature gauge climbs into the red, a coolant leak is the most likely cause. A hose that can't hold pressure won't keep your engine cool, leading to serious and expensive damage if ignored.
- Visible Hose Damage: A visual inspection can reveal a lot. Look for hoses that are swollen, bulging, cracked, or feel spongy and soft when you squeeze them (when the engine is cold). Any of these signs mean the hose's internal structure is compromised and it needs immediate replacement.
- Low Coolant Light: If the low coolant warning light on your dashboard comes on, it means you have a leak somewhere in the system. A failing radiator hose is a primary suspect.
Choosing the Right Aftermarket Hose
When replacing a radiator hose on your Acadia, you don't have to buy the part from a GM dealer. High-quality aftermarket brands offer excellent performance, often at a better price. For the 2007-2017 Acadia, the OEM provider is ACDelco. Your main aftermarket choices are Continental, Dayco, and Gates.

| Premium Aftermarket | Gates, Continental | Both are highly respected brands that often supply parts directly to automakers. Gates is frequently praised by professional mechanics and DIYers for excellent material quality and precise fitment, engineered to resist electrochemical degradation, a leading cause of failure. Continental is another top-tier choice with a strong reputation. |
| Standard Aftermarket | Dayco | Dayco provides a reliable, budget-friendly option. While some users have noted occasional fitment differences compared to Gates or OEM, they are a major brand and their hoses are widely used with success. |
Pro Tip: Replace Hoses and Clamps in Pairs
