What Does The Mercedes G55 Auxiliary Water Pump Do?
The Mercedes G55 auxiliary water pump helps keep the engine at a steady temperature, especially when the car isn’t moving much. It moves coolant through the system when regular flow might be low, like while sitting at a red light or in heavy traffic. This keeps heat from building up in the engine. The pump also helps the cabin heat work better at idle, so you get warm air on cold days even when parked or crawling in traffic. Without this pump, engines sometimes get too warm, and the heater doesn’t work as well when you really need it.
What Are Common Symptoms Of A Failing Mercedes G55 Auxiliary Water Pump?
If your Mercedes G55 auxiliary water pump starts to fail, the signs show up in a few ways. Maybe the heat in your car feels weak when stopped, but seems to work when you’re driving faster. Sometimes, the engine temperature rises too high at low speeds, especially if you’re waiting in traffic. Odd sounds like whining or grinding near the pump are another red flag. The dash might show a warning light or the temp gauge might spike. Finding these signs early lets you fix the issue before it causes bigger trouble for your engine or your comfort.
How Do You Test The Mercedes G55 Auxiliary Water Pump?
Testing a Mercedes G55 auxiliary water pump isn’t too tricky. Look for leaks or broken parts with the engine off and cool. Turn on the engine and the heater, and listen close—if the pump buzzes or vibrates, it’s likely working. You can touch the hoses going in and out of the pump; both should warm up when things are running right. If you’re handy, check with a volt meter to see if power gets to the pump plug. Sometimes, holding your hand on the pump will let you feel if it’s spinning inside. For a more in-depth check, some shops have tools to measure the flow or even watch it work in real time.
Is It Safe To Drive With A Bad Mercedes G55 Auxiliary Water Pump?
Driving with a broken Mercedes G55 auxiliary water pump puts your engine at risk, especially in slow traffic or during long waits. The main coolant flow might not be enough, raising coolant temperatures and cutting heat in the cabin. In the worst case, the engine could overheat and end up with real damage. While some can make short trips at higher speeds without major issues, running a car this way isn’t smart for long. You’re better off fixing the pump as soon as you notice a problem, saving yourself bigger repairs and keeping your engine safe.
How Much Does It Cost To Replace The Mercedes G55 Auxiliary Water Pump?
Replacing a Mercedes G55 auxiliary water pump costs more if you go through a shop, but some do their own repairs. The pump alone usually sits around $200 to $400. Labor adds another $150 to $300, since you often need to remove other parts and drain the coolant. Most spend between $350 and $700 all told at a repair shop. If you’re good with tools and tackle it on your own, you just pay for the pump. No matter what, calling around for a few quotes and using a good part, whether it’s OEM or solid aftermarket, can save some cash.
