In this article, you’ll learn how to diagnose common problems, get a full tool and parts list, follow our detailed replacement instructions, and discover some pro tips to keep your cooling system in top shape for years to come.
What Does the Thermostat on Your Can-Am Outlander Actually Do?
Think of the thermostat as the bouncer for your engine’s cooling system. It’s a simple, temperature-sensitive valve that sits between the engine and the radiator, controlling the flow of coolant.
When you first start your Outlander, the engine is cold. The thermostat stays closed, blocking coolant from going to the radiator. This allows the engine to warm up to its optimal operating temperature quickly, which is crucial for performance and fuel efficiency.
Once the engine reaches its target temperature (usually around 180-195°F or 82-90°C), the wax inside the thermostat melts and expands, pushing a piston that opens the valve. This allows hot coolant to flow to the radiator to be cooled, and cooler coolant to flow back into the engine. It’s a constant balancing act to keep your engine perfectly happy.
Why a Tiny Valve is a Big Deal
This little part has a huge job. A properly functioning thermostat ensures:
- Fast Warm-Up: Reduces engine wear during cold starts.
- Stable Operating Temp: Prevents overheating under load and running too cold in winter.
- Optimal Performance: An engine at the right temperature runs more efficiently and produces more power.
- Engine Longevity: Protecting your engine from the extreme stress of overheating is its most important role.
Telltale Signs of a Failing Can-Am Outlander Thermostat
A thermostat can fail in two ways: stuck closed or stuck open. Each has its own set of symptoms. Learning to spot these common problems with thermostat can am outlander can save you from a costly engine repair down the road.
Symptom 1: Engine Overheating (Stuck Closed)
This is the most common and dangerous failure. When the thermostat is stuck shut, hot coolant can’t get to the radiator. The engine temperature will climb rapidly, especially under load or when idling.
You’ll see the temperature gauge spike, the warning light will come on, and you might even see steam or smell burning coolant. If this happens, shut the engine off immediately to prevent catastrophic damage.
Symptom 2: Engine Running Too Cool (Stuck Open)
If the thermostat is stuck open, coolant is constantly flowing to the radiator. This makes it very difficult for the engine to reach its proper operating temperature, especially in cooler weather.
Signs of this include your temperature gauge never reaching the normal range, poor performance from your cabin heater (if you have one), and a noticeable drop in fuel economy. While not as immediately damaging as overheating, it’s still not good for your engine long-term.
Symptom 3: Erratic Temperature Readings
Is your temperature gauge bouncing around like a tachometer? This can indicate a thermostat that is sticking or opening and closing erratically. It can’t decide what to do, leading to unstable engine temperatures.
Symptom 4: Coolant Leaks
Sometimes the thermostat itself is fine, but the gasket on the housing fails. You might notice coolant puddles under your machine or see crusty, colored residue around the thermostat housing. This is a clear sign that something needs attention.
The Complete Guide to Replacing Your Thermostat Can-Am Outlander
Ready to get your hands dirty? This job is well within the reach of a weekend DIYer with basic tools. Following this thermostat can am outlander guide will make the process smooth and successful. Let’s walk through how to thermostat can am outlander replacement step-by-step.
H3: Tools and Parts You’ll Need
Gather everything before you start to avoid a mid-job run to the auto parts store.
- Socket set with extensions (metric)
- Pliers (channel lock and needle-nose)
- Drain pan
- Funnel
- Shop rags or paper towels
- Scraper or razor blade (for gasket removal)
- New OEM or quality aftermarket thermostat (make sure it’s the correct temperature rating for your model)
- New thermostat housing gasket
- Premixed 50/50 coolant compatible with your Can-Am (check your owner’s manual)
H3: Safety First – Pre-Job Checklist
NEVER work on a hot cooling system. Pressurized, hot coolant can cause severe burns.
- Let the engine cool completely. We mean it. Wait several hours or overnight. The radiator cap should be cool to the touch.
- Park on a level surface.
- Wear safety glasses and nitrile gloves. Coolant is toxic.
H3: Step-by-Step Replacement Process
The exact location can vary slightly by model and year, but the thermostat is almost always located where the upper radiator hose connects to the engine.
- Access the Area: You’ll likely need to remove some plastic body panels or the front rack to get clear access to the engine.
- Drain the Coolant: Place your drain pan under the radiator. Slowly and carefully open the radiator cap to release any residual pressure. Locate the drain plug on the bottom of the radiator or simply use your pliers to loosen the clamp on the lower radiator hose and pull it off the radiator. Only drain enough coolant so the level is below the thermostat housing.
- Locate the Thermostat Housing: Follow the large upper radiator hose from the top of the radiator to where it connects to the engine. That metal or plastic piece it connects to, typically held on by two or three bolts, is the thermostat housing.
- Remove the Housing: Use your socket set to remove the bolts holding the housing in place. A little wiggle should be enough to break it free. Have a rag handy to catch any spilled coolant.
- Remove the Old Thermostat: Pull the old thermostat out. Pay close attention to its orientation—which end was pointing up/out? The new one must go in the same way. There’s usually a small “jiggle pin” or bleed valve that should be positioned at the top.
- Clean the Mating Surfaces: This is a critical step. Use a plastic scraper or razor blade (be very careful not to gouge the aluminum) to remove every trace of the old gasket from both the engine block and the thermostat housing. The surfaces must be perfectly clean and smooth for the new gasket to seal properly.
- Install the New Thermostat and Gasket: Place the new thermostat into the recess in the engine, ensuring it’s oriented correctly. Then, place the new gasket on top, aligning the bolt holes.
- Reinstall the Housing: Carefully place the housing back on and start the bolts by hand. Tighten them down evenly in a crisscross pattern to ensure even pressure on the gasket. Don’t overtighten and strip the threads!
- Refill and Bleed the System: Reconnect any hoses you removed. Using a funnel, slowly pour new coolant into the radiator until it’s full. Now, you need to “burp” or bleed the air out. Squeeze the upper and lower radiator hoses repeatedly to help force air bubbles out. You should see the coolant level in the radiator drop as air escapes. Top it off again.
- Final Check: Leave the radiator cap off. Start the engine and let it idle. As it warms up and the thermostat opens, you should see the coolant level drop again. Top it off as needed. Once the level is stable and you see coolant circulating, put the radiator cap back on. Check for any leaks around the housing you just worked on. Let the machine run until the cooling fan cycles on and off at least once.
Pro Tips and Best Practices for Your Thermostat Can-Am Outlander
Doing the job is one thing; doing it like a pro is another. Here are some thermostat can am outlander tips and best practices to ensure long-term reliability.
The Importance of Bleeding the System
We mentioned it above, but it’s worth repeating. An air bubble trapped in the cooling system (an “airlock”) can get stuck at the thermostat or water pump and prevent coolant from circulating, causing an overheat condition even with a brand new thermostat. Taking the time to properly bleed the system is the most important part of this whole thermostat can am outlander care guide.
Choosing the Right Parts
While aftermarket parts can save a few bucks, the thermostat is not the place to cheap out. An OEM thermostat is designed specifically for your machine’s operating parameters. At the very least, use a high-quality replacement from a reputable brand. And always use a new gasket.
While You’re In There…
Since you have the system drained and plastics off, it’s the perfect time to inspect a few other things. Check the radiator hoses for cracks, bulges, or soft spots. Squeeze them to feel for brittleness. Check the hose clamps to ensure they are tight and not rusted. This is one of the key benefits of thermostat can am outlander replacement—it forces you to inspect the entire cooling system.
The Eco-Friendly Angle: Sustainable Thermostat Can-Am Outlander Maintenance
Being a responsible rider extends to how we maintain our machines. When working on your cooling system, think about the environmental impact.
Ethylene glycol, the primary ingredient in most coolants, is highly toxic to pets and wildlife. Never drain coolant onto the ground. Always use a drain pan and take the old coolant to your local auto parts store or municipal hazardous waste facility for proper recycling. This is a core part of sustainable thermostat can am outlander maintenance.
Furthermore, a properly working thermostat ensures your engine runs at its most efficient temperature. This means better fuel combustion, which translates to lower emissions and better gas mileage on the trail. An eco-friendly thermostat can am outlander isn’t about the part itself, but about how a functional part contributes to a cleaner-running machine.
Frequently Asked Questions About the Can-Am Outlander Thermostat
How often should I replace my Outlander’s thermostat?
There is no set replacement interval. It’s not a routine maintenance item. However, it’s a good practice to replace it preventatively whenever you perform a full coolant flush, which should be done every 2-4 years depending on your riding conditions. Otherwise, replace it at the first sign of trouble.
Can I run my Outlander without a thermostat?
We strongly advise against this. While it might seem like a quick fix for an overheating issue, it will cause your engine to run too cool. This leads to poor fuel atomization, increased engine wear, carbon buildup, and reduced overall performance. The engine management system is designed to operate within a specific temperature window that you can’t achieve without a thermostat.
What temperature thermostat should I use?
For 99% of riders, the answer is simple: use the temperature rating specified by the manufacturer (OEM). It’s engineered for the best all-around performance for your specific engine. Using a lower-temperature thermostat won’t necessarily prevent overheating and can cause the issues mentioned above.
My Outlander is still overheating after replacing the thermostat. What’s next?
If a new thermostat didn’t fix your overheating problem, it’s time to look elsewhere. The most common culprits are:
- An airlock in the system (try bleeding it again).
- A radiator clogged externally with mud or internally with scale.
- A faulty cooling fan or fan sensor.
- A failing water pump (look for leaks from the “weep hole”).
- In rare cases, a blown head gasket.
Tackling your Can-Am Outlander’s thermostat is a rewarding project that builds your skills and saves you money. It’s a small part that plays a giant role in the health and performance of your ride. By following this guide, you can ensure your machine stays cool under pressure, letting you focus on what really matters: the trail ahead.
