What Does The Mercedes GLS63 AMG Auxiliary Water Pump Do?
The Mercedes GLS63 AMG auxiliary water pump plays a big role behind the scenes. When you’re moving slow or the engine’s idling, the usual water pump doesn’t circulate as much coolant. That’s where the auxiliary pump steps in. It keeps coolant moving through the turbochargers and heater core, which is crucial for keeping both the engine and the cabin at the right temperature. This is even more important in a high-powered SUV like the GLS63 AMG—there’s a lot of extra heat when you push the engine. The pump helps protect against overheating and lets you enjoy warm cabin air in the winter, even before you start driving.
How Can I Tell If My Mercedes GLS63 AMG Auxiliary Water Pump Is Failing?
If the Mercedes GLS63 AMG auxiliary water pump is on the way out, it usually gives you some signs. You may notice the heat isn’t getting warm at idle, especially in cold weather. The engine temperature could creep up when you’re sitting in traffic. Sometimes you’ll see a puddle of coolant underneath, often near the passenger side. Warning lights or odd error codes about coolant flow can show up on the dash. Listen for whining or grinding sounds under the hood. If you catch any of these, the pump could be the culprit. Don’t wait to get things checked out—ignoring it could lead to bigger problems down the road.
Where Is The Auxiliary Water Pump Located On The Mercedes GLS63 AMG?
You’ll find the Mercedes GLS63 AMG auxiliary water pump tucked into the front passenger side of the engine bay. It often sits close to the firewall, behind some covers or beneath the intake pipes. It’s a small unit attached to the hoses that run to the heater core and turbo cooling system. Access isn’t complicated but you’ll need to remove a panel or two. Always make sure the engine is cool before you start poking around—coolant and engine parts stay hot longer than you'd think.
Is It Safe To Drive With A Bad Auxiliary Water Pump In My Mercedes GLS63 AMG?
It’s not a great idea to drive with a busted Mercedes GLS63 AMG auxiliary water pump. Even though the main coolant pump handles most of the system, the auxiliary pump keeps some key areas safe, like your turbos. If it stops working, you risk overheating. In a worst-case scenario, you could end up with engine damage, or your turbochargers could get too hot. Both are expensive fixes. If you notice issues with heat or cooling, schedule a repair as soon as possible.
What’s Involved In Replacing The Mercedes GLS63 AMG Auxiliary Water Pump?
To swap out the Mercedes GLS63 AMG auxiliary water pump, you start by disconnecting the battery and releasing any pressure in the cooling system. Some covers or trims might need to come off for better access. The pump is unplugged from its wires and hoses. If any coolant spills, catch it with a drain pan. The new pump goes back in using the same connections, and you tighten up the clamps. Refill the cooling system, get rid of air in the lines, hook up the battery, and start the engine. Check for any leaks or warning lights. Many owners hand this job over to a mechanic, since bleeding the cooling system wrong can cause overheating later.
