Understanding where to find it is the first step whether you’re planning maintenance, diagnosing a potential issue, or simply expanding your knowledge of your vehicle’s mechanics.

Introduction to the 2017 Jeep Grand Cherokee Overland

The 2017 Jeep Grand Cherokee Overland represents a premium trim level in the Grand Cherokee family. It combines luxury amenities with Jeep’s renowned off-road capability. The Overland features distinctive styling, premium interior appointments, and advanced technology options that set it apart from other Jeep Cherokee models.

As one of Jeep’s flagship vehicles, the Grand Cherokee Overland comes equipped with a choice of powerful and efficient engines. Each engine has its own cooling system configuration. At the heart of this cooling system is the water pump – a crucial component responsible for circulating coolant throughout the engine.

The Water Pump: Function and Critical Importance

Your Grand Cherokee’s water pump is essentially the heart of the cooling system. It continuously circulates coolant through the engine block, cylinder heads, radiator, and heater core. This circulation maintains optimal engine temperature regardless of driving conditions.

This seemingly simple component performs a vital function: it prevents engine overheating that could lead to severe mechanical damage. The water pump creates pressure that moves coolant through passages within the engine. The coolant absorbs heat from combustion and transfers it to the radiator where it dissipates into the atmosphere.

The pump operates whenever your engine is running. The serpentine belt (or timing belt in some engines) typically drives it. The impeller inside the pump spins, creating centrifugal force that pushes coolant through the entire system.

Failure of this critical component can quickly lead to overheating, potential engine damage, and being stranded. That’s why knowing its location and understanding how it works is essential for any Grand Cherokee owner.

Cooling System Architecture in the 2017 Grand Cherokee

To understand where the water pump is located, it helps to know how the entire cooling system works in your Jeep Grand Cherokee.

The cooling system follows a closed loop design. Coolant travels from the radiator (located at the front of your vehicle) into the engine. The water pump creates the pressure that circulates this coolant through internal engine passages where it absorbs heat.

The heated coolant then flows back to the radiator. It passes through a thermostat that regulates flow based on engine temperature. In the radiator, heat transfers to the outside air (assisted by cooling fans when necessary), and the cycle continues.

Additional components include the coolant reservoir, various hoses, and the heater core. The coolant reservoir accommodates expansion and contraction of the coolant. The heater core provides cabin heat.

The water pump’s specific location within this system depends on your engine type. It’s always positioned to efficiently circulate coolant through the engine block and cylinder heads.

Water Pump Function and Design in the Grand Cherokee

The water pump in your 2017 Grand Cherokee combines simplicity with reliability. At its core is an impeller (similar to a fan) that spins rapidly within the pump housing.

As the impeller rotates, centrifugal force draws coolant from the lower radiator hose into the center of the pump. The spinning action then forces this coolant outward and into the engine block and cylinder heads.

The pump housing is typically made of aluminum or cast iron to withstand heat and pressure. A shaft connects the external pulley to the internal impeller. Bearings support this shaft, allowing smooth rotation.

A mechanical seal prevents coolant from leaking where the shaft enters the pump housing. This seal is often the first part to fail. Failure results in coolant leaks that appear as drips from the front of the engine or around the water pump housing.

The outside of the pump features a mounting flange with bolt holes that secure it to the engine. It also has inlet/outlet ports where hoses or internal passages connect.

Precise Location of the Water Pump in the 3.6L Pentastar Engine

If your 2017 Grand Cherokee Overland has the 3.6L Pentastar V6 engine (the most common option), the water pump is located at the front of the engine on the passenger side. It mounts directly to the timing cover and the serpentine belt drives it.

To locate it, first identify the serpentine belt – the long, ribbed belt that wraps around multiple pulleys at the front of the engine. The water pump pulley is one of several pulleys driven by this belt. You’ll typically find it on the right side of the engine when viewed from the front of the vehicle.

The water pump pulley is smooth (unlike some other pulleys which have grooves) and bolts directly to the water pump shaft. The actual pump body sits behind this pulley, mounted to the timing cover. Only the pulley and a small portion of the pump housing are visible without removing components.

You’ll notice the water pump is positioned near the lower radiator hose connection. It may have smaller hoses connected to it as well. These connections allow coolant to flow into and out of the pump.

Precise Location of the Water Pump in the 5.7L Hemi Engine

For 2017 Grand Cherokee Overlands with the optional 5.7L Hemi V8 engine, the water pump is also located at the front of the engine but with some differences from the V6 version.

On the Hemi, the water pump mounts behind the timing chain cover at the front of the engine. Like the V6, the serpentine belt drives it. This belt wraps around various accessory pulleys.

To find it, look at the front right (passenger side) of the engine. The water pump pulley will be visible as one of the pulleys driven by the serpentine belt. It’s typically a smooth pulley without grooves.

The pump itself bolts to the timing chain cover, with most of its body hidden behind this cover. You’ll only see the pulley and perhaps a small portion of the pump housing during a visual inspection.

The 5.7L Hemi’s water pump design is specific to this engine family. It has different mounting points and slightly different coolant flow patterns compared to the V6 engine.

Identifying the Water Pump Visually – What to Look For

When trying to locate your Grand Cherokee’s water pump, these visual cues will help you identify it:

The most obvious identifier is the water pump pulley – a round, metal wheel typically 3-4 inches in diameter. Unlike some other pulleys in the engine bay (like the alternator), the water pump pulley is usually smooth without grooves.

Look for a pulley that the serpentine belt drives on the front passenger side of the engine. The water pump is directly behind this pulley.

You might notice coolant hoses or connections near the water pump. These aren’t always easily visible without looking underneath or removing covers.

On some engines, you might see a portion of the pump housing – typically made of aluminum or cast iron with a somewhat circular shape.

Look for mounting bolts around the perimeter of the pump that secure it to the engine block or timing cover.

Sometimes a small amount of dried coolant residue or staining can help identify the pump location. This occurs because the mechanical seal is a common leak point.

Tools Required for Water Pump Location and Access

To properly locate and inspect your Grand Cherokee’s water pump, you’ll need a few basic tools:

A good flashlight is essential – LED models work best for illuminating the dark recesses of the engine bay.

An inspection mirror with an extendable handle helps view components that aren’t directly visible. This is particularly helpful for seeing behind pulleys and hoses.

Basic hand tools like screwdrivers and socket wrenches may help if you need to remove any plastic engine covers or shields for better access.

Safety glasses protect your eyes from debris, fluids, or other hazards during inspection.

Work gloves shield your hands from hot engine components and sharp edges.

If you’re planning to do more than just locate the pump, you might need specialized tools like pulley removal tools and torque wrenches. These aren’t necessary for simple identification.

Having the right tools ready makes finding your water pump much easier and safer.

The 5.7L Hemi’s water pump integrates more with the front timing cover assembly compared to some other engines. This makes it less visible but still identifiable by its pulley and partial housing.

Common Water Pump Failure Symptoms in the 2017 Grand Cherokee

Knowing what signs indicate water pump problems can help you catch issues early before they lead to serious engine damage:

Coolant leaks are the most common sign of water pump problems. Look for puddles of green, orange, pink, or yellow fluid beneath your Jeep, particularly around the front end. These leaks often result from a failing seal where the pump shaft enters the housing.

Engine overheating is a serious symptom that you should never ignore. If your temperature gauge rises into the red zone or you see a temperature warning light, your water pump may not be circulating coolant properly.

Unusual noises like whining, grinding, or squealing from the front of the engine can indicate water pump bearing failure. These sounds typically increase with engine speed.

A loose or wobbling water pump pulley suggests bearing failure within the pump. Watch the pulley while the engine is running (from a safe distance) to check for wobbling movement.

Steam from under the hood indicates that coolant is boiling over due to severe overheating. This emergency situation might result from water pump failure.

Coolant mixing with engine oil creates a milky, frothy substance on your dipstick or oil cap. While this often indicates a head gasket problem, it can result from severe overheating caused by water pump failure.

Frequent need to add coolant without visible leaks may indicate that coolant is leaking internally or evaporating due to overheating issues related to water pump problems.

If you notice any of these symptoms, promptly inspect and possibly replace your water pump to prevent more extensive engine damage.

Water Pump Replacement Options, Costs, and Considerations

If your water pump needs replacement, you have several options to consider:

Dealership service offers factory-trained technicians and OEM (Original Equipment Manufacturer) parts. Expect to pay between $500-$800 for a complete water pump replacement at a Jeep dealership, depending on your engine type. While this is the most expensive option, it typically comes with a stronger warranty and guaranteed compatibility.

Independent repair shops generally charge 20-30% less than dealerships, typically $400-$650 for the same job. Many independent mechanics are familiar with Jeep vehicles and can provide quality service with OEM or high-quality aftermarket parts.

DIY replacement is possible but challenging for most owners. Parts costs range from $60-$150 for the pump itself, plus additional costs for coolant, gaskets, and possibly timing components if they need replacement. However, the job requires significant mechanical knowledge, specialized tools, and several hours of work.

When considering replacement options, factor in these important points:

Water pump replacement often involves draining and refilling the cooling system with fresh coolant
On many Grand Cherokee engines, you must remove timing components to access the water pump
You might need to replace additional components while the area is accessible (timing belt/chain, tensioners, etc.)
Using the correct coolant type and properly bleeding the cooling system is critical to prevent future issues

For most owners, professional replacement works best due to the complexity of the job and the critical nature of proper installation.

Preventative Maintenance for Water Pump Longevity

Keep your 2017 Grand Cherokee’s water pump operating reliably with these preventative maintenance practices:

Follow the recommended coolant change intervals in your owner’s manual – typically every 5 years or 100,000 miles for most Jeep vehicles. Fresh coolant contains important additives that protect the water pump seals and prevent corrosion.

Inspect the serpentine belt regularly for wear, cracks, or glazing. A failing belt can damage the water pump or cause it to stop functioning.

Check for leaks periodically by looking for coolant residue or wet spots around the water pump area and beneath your vehicle.

Maintain proper coolant level and mixture according to Jeep specifications. Low coolant levels increase stress on the water pump.

Address overheating promptly – never continue driving if your temperature gauge shows excessive heat. Overheating can damage the water pump and many other engine components.

Use the correct coolant type as specified in your owner’s manual. Modern engines require specific coolant formulations. Using the wrong type can cause premature water pump failure.

Listen for unusual noises when starting your engine and during operation. Early detection of bearing wear can save you from more extensive repairs.

By following these preventative measures, you can significantly extend the life of your water pump and avoid unexpected failures.
