You’re deep on the trail, miles from the truck, when that dreaded temperature light flashes on your dash. Your heart sinks. An overheating engine in the backcountry is more than an inconvenience; it’s a potential ride-ender and can lead to catastrophic engine damage.
You’ve probably been there, or at least feared it. That feeling of helplessness is something every rider wants to avoid. What if you could not only spot the warning signs early but also have the confidence to tackle the fix yourself?
In this complete guide, we’re pulling back the curtain on one of the most critical components of your rig’s cooling system: the can am outlander water pump. We’ll walk you through identifying common problems, give you a step-by-step replacement guide, and share some pro tips to keep your machine running cool for years to come. Let’s get you back on the trail with confidence.
What Does the Can-Am Outlander Water Pump Do, Anyway?
Think of your water pump as the heart of your Outlander’s cooling system. It’s a relatively simple device with a monumental job: circulating coolant (antifreeze) from the radiator, through the engine’s cooling passages, and back again.
This constant circulation pulls destructive heat away from critical engine components like the cylinder and head. Without it, your engine would overheat in minutes, leading to warped parts, blown gaskets, and a massive repair bill.
Inside the pump, an impeller, which looks like a small fan, is spun by the engine via a shaft. This spinning action is what creates the pressure to move the coolant. The whole assembly is protected by seals and bearings to keep coolant in and dirt out.
Telltale Signs of a Failing Water Pump: Common Problems to Watch For
Your Outlander is usually pretty good at telling you when something is wrong. You just have to know what to look—and listen—for. Catching these signs early is key to avoiding a major breakdown. This is the first step in our can am outlander water pump guide.
The Dreaded Coolant Leak
The most common sign of a failing water pump is a coolant leak. Most pumps have a small “weep hole” on the underside. This is a diagnostic feature designed to let you know when the internal seal has failed.
If you see drips of green, pink, or orange coolant coming from this hole or notice a puddle under your machine after it’s been sitting, it’s a clear signal that the seal is compromised. Don’t ignore it; it will only get worse.
Overheating Engine
If your temperature gauge is climbing higher than normal or the warning light is coming on during a ride, your water pump could be the culprit. A failing pump can’t circulate coolant effectively.
This can happen for two reasons: the internal bearing is seizing up, preventing the impeller from spinning at the correct speed, or the impeller itself is worn or damaged and can no longer move fluid efficiently.
Strange Noises from the Engine Bay
Turn off the music and listen to your engine. A failing water pump bearing will often make a distinct noise. You might hear a low-pitched grinding, a high-pitched whine, or even a rattling sound coming from the side of the engine where the pump is located.
This noise will typically change with engine RPM, getting louder and faster as you give it throttle. This is the sound of the internal bearings destroying themselves.
Wobbly Pulley or Fan
With the engine off and cool, grab the water pump pulley (or the fan, if it’s attached to the pump on your model) and try to wiggle it. There should be absolutely no side-to-side or in-and-out play.
If you can feel any looseness or wobble, the bearing has failed. This is a critical failure sign, as a wobbly pulley can throw the drive belt and cause other damage.
Your Ultimate Can-Am Outlander Water Pump Replacement Guide
Alright, you’ve diagnosed the problem. Now it’s time to roll up your sleeves. Replacing a can am outlander water pump is a very manageable job for a DIY mechanic with the right tools and patience. Here’s how to get it done right.
Safety First: Pre-Job Checklist
- Let It Cool Down: Never work on a hot cooling system. Pressurized, scalding coolant is extremely dangerous. Let the machine cool completely for several hours.
- Disconnect the Battery: Disconnect the negative battery terminal to prevent any accidental starts.
- Gear Up: Wear safety glasses and nitrile gloves. Coolant is slippery and toxic.
Tools and Parts You’ll Need
- Socket and ratchet set (metric)
- Torque wrench (essential for proper reassembly)
- Pliers (for hose clamps)
- A clean drain pan
- Gasket scraper (plastic is best to avoid gouging aluminum surfaces)
- Scotch-Brite pad and brake cleaner
- New Can-Am Outlander water pump assembly (with gaskets/seals)
- Fresh, BRP-recommended coolant
- Distilled water (if you are mixing concentrated coolant)
Step-by-Step Replacement Process
- Drain the Coolant: Place your drain pan under the ATV. Locate the radiator drain plug or simply remove the lowest radiator hose at the water pump connection to drain the system. Be prepared for a rush of fluid.
- Remove Obstructions: You’ll likely need to remove some plastic body panels and possibly the floorboard to get clear access to the water pump cover on the side of the engine.
- Remove Hoses: Use pliers to release the clamps on the hoses connected to the water pump housing and carefully twist them off. Some gentle persuasion may be needed if they’re stuck on.
- Unbolt the Old Pump: Remove the bolts holding the water pump cover and the pump assembly to the engine case. Keep track of which bolt came from which hole, as they can sometimes be different lengths.
- Clean the Mating Surface: This is the most critical step. Use your plastic scraper and Scotch-Brite pad to meticulously clean every bit of old gasket material from the engine case. The surface must be perfectly clean and smooth for the new gasket to seal properly. Wipe it down with brake cleaner for a final prep.
- Install the New Pump: Install the new gasket and water pump assembly. Make sure any dowel pins are correctly aligned. Start all the bolts by hand to ensure they aren’t cross-threaded.
- Torque to Spec: Use your torque wrench to tighten the bolts in a star or crisscross pattern to the manufacturer’s specified torque. Do not just guess and overtighten; this can warp the housing or damage the threads.
- Reconnect and Refill: Re-attach the coolant hoses and tighten the clamps. Close the radiator drain plug. Now, slowly refill the cooling system with a 50/50 mix of the correct coolant and distilled water.
The Critical Final Step: Bleeding the System
You can’t just fill it and ride. Air gets trapped in the cooling system and creates hot spots that can damage your engine. You must bleed it properly.
Most Outlanders have a bleed screw on the thermostat housing or on the cylinder head. Loosen this screw as you fill the radiator. When a steady stream of coolant comes out with no air bubbles, tighten it. Then, start the engine with the radiator cap off, let it warm up, and top off the coolant as the level drops. This is one of the most important can am outlander water pump tips we can offer.
Pro Tips for Water Pump Longevity: Best Practices and Care Guide
Want to avoid doing this job again anytime soon? A little preventative maintenance goes a long way. Following these can am outlander water pump best practices will maximize the life of your new pump.
Use the Right Coolant
It’s tempting to grab any jug of antifreeze off the shelf, but don’t. BRP engines are designed for a specific type of coolant chemistry. Using the wrong kind can degrade seals and gaskets prematurely, leading to early failure of your new pump.
Regular Coolant Flushes
Over time, coolant breaks down and becomes corrosive. Follow the service interval in your owner’s manual and perform a full system flush. Fresh coolant lubricates the water pump seal and prevents corrosion, which is a major benefit for the entire system.
The Eco-Friendly Approach to Maintenance
Part of being a responsible rider is protecting the trails we love. When you drain your old coolant, capture it in a sealed container. It is highly toxic to animals and the environment. Never dump it on the ground or down a storm drain.
Most auto parts stores or local hazardous waste facilities will accept used antifreeze for free. This is the core of having a sustainable can am outlander water pump care routine—properly managing the waste products. Preventative care itself is eco-friendly, as it prevents a catastrophic trail-side failure and fluid spill.
OEM vs. Aftermarket: Choosing the Right Water Pump
When buying a new pump, you’ll face a choice: stick with the Original Equipment Manufacturer (OEM) part from BRP or go with an aftermarket brand?
The Case for OEM
An OEM pump is a guaranteed perfect fit with known quality. You’re getting the exact same part your machine was built with. The downside is usually a higher price tag.
The Allure of Aftermarket
Reputable aftermarket brands like All Balls Racing or Moose Racing often offer high-quality replacement kits for a lower price. Some even offer upgraded components, like billet aluminum impellers that are stronger than the stock plastic ones. The risk lies with no-name brands, where quality control can be a gamble.
Our Recommendation
For most weekend warriors and DIY mechanics, a high-quality aftermarket kit from a trusted brand offers the best balance of price, performance, and reliability. If you demand absolute peace of mind and the budget allows, you can never go wrong with OEM.
Frequently Asked Questions About the Can-Am Outlander Water Pump
How often should I replace my Can-Am Outlander water pump?
The water pump is generally considered a “replace when it fails” component. There isn’t a set replacement interval. However, it’s wise to inspect it for leaks or bearing play any time you’re doing a major service or a coolant flush.
Can I just replace the seal instead of the whole pump?
While seal kits are available, it’s usually not recommended. The labor involved to press out the old seal and bearing is significant. If the seal has failed, the bearing has likely been contaminated and is not far behind. Replacing the entire assembly is faster, easier, and much more reliable.
What happens if I ignore a failing water pump?
Ignoring the warning signs is the worst thing you can do. A complete failure will cause your engine to overheat rapidly, leading to a blown head gasket, a warped cylinder head, or even a seized engine. This turns a couple-hundred-dollar repair into a multi-thousand-dollar engine rebuild.
Is this a beginner-friendly DIY job?
We’d rate this as an intermediate-level job. If you are comfortable draining fluids, removing body panels, and using a torque wrench, you can absolutely do this. If you’re new to wrenching, it might be best to watch a few videos or ask a mechanically-inclined friend for help.
Tackling a job like a can am outlander water pump replacement is incredibly rewarding. It saves you money, teaches you more about your machine, and gives you the confidence to handle problems on the trail. By understanding how it works, what to watch for, and how to replace it, you’ve taken a huge step toward becoming a more capable and self-reliant rider.
So gather your tools, take your time, and follow the steps. You’ve got this. Now get that Outlander fixed up and we’ll see you back on the dirt. Ride safe!
