Subaru Forester Windshield Washer Pump Replacement Guide: 2006-2014
If your washer fluid isn't spraying, the pump might be the problem—here's what Forester owners need to know.
- Your Forester has two separate pumps for the front and rear windows; if one works, the other has likely failed.
- Before replacing the pump, check for brittle or broken plastic hose connectors under the cowl, a common failure point.
- Replacement is a simple DIY job, accessible through the front passenger wheel well.
- Always replace the rubber grommet with the pump to ensure a leak-free seal.
Is Your Washer Pump Failing?
When a washer pump fails, the most common sign is that nothing happens when you try to clean your windshield. You might hear a faint hum from the pump motor but get no spray, or you might hear nothing at all. If you see a puddle of blue, green, or orange fluid under the front passenger side of your Forester, the pump's housing may have cracked or the rubber seal where it meets the reservoir may have failed. This can happen from age or if water in the system freezes and expands.
Check This Before You Buy a New Pump
Sometimes, a lack of spray isn't the pump's fault. On many Subarus, including the Forester, the plastic hose connectors (specifically a 'Y' or 'T' shaped splitter) under the windshield cowl can become brittle over time and crack. This causes fluid to leak out before it reaches the nozzles. If you can hear your pump running but the spray is weak or non-existent, check for leaks under the hood near the base of the windshield wipers 🎬 Watch: How to replace a cracked Y-adapter hose connector before replacing the pump.
Choosing the Right Aftermarket Pump
When it's time to replace the pump, you have two main choices: a new OEM (Original Equipment Manufacturer) part from Subaru or a new aftermarket part from a brand like Trico. For a straightforward part like a washer pump, an aftermarket replacement is often a smart, budget-friendly choice. Brands like Trico design their pumps to be a direct fit, making installation simple without needing to drill holes or make adjustments. There is no evidence from owner forums that suggests an aftermarket pump is less reliable than the original for this specific job. Both types can eventually fail from a burned-out motor or a cracked housing.
| Part Type | Estimated Cost |
|---|---|
| New OEM Subaru Pump | $45 - $60 |
| New Aftermarket Pump (Trico) | $35.01 |
| Shop Labor | $90 - $105 |
Installation Tips for Forester Owners
Replacing the washer pump on a 2006-2014 Forester is a job most DIYers can handle in under an hour. The washer fluid reservoir and its pumps are located in the front passenger-side wheel well. You will need to jack up the vehicle and remove the front passenger wheel for the best access. After removing a few plastic clips holding the fender liner, you can pull it back to see the reservoir. The pumps are press-fit into the bottom of the tank. Simply disconnect the electrical plug and the fluid hose, and carefully wiggle the old pump out. 🎬 See this walkthrough for replacing the pump and hoses Have a bucket ready, as the remaining fluid will drain out when the pump is removed.
Pro Tip: Always replace the small rubber grommet that seals the pump to the reservoir. New aftermarket pumps often include a new grommet. This cheap part is critical for preventing leaks with your new pump.
Frequently Asked Questions
Are the front and rear washer pumps the same on a 2006-2014 Forester?
Yes, for most models in this year range, the front and rear pumps are the same part and can be used in either position. They are mounted in two separate spots on the same fluid reservoir.
How do I know if the pump is bad or if the line is just clogged?
First, listen. If you activate the washer and hear no sound from the pump motor, check the fuse first. 🎬 Watch: A mechanic's guide to troubleshooting a dead washer pump If the fuse is good, the pump is likely dead. If you hear the pump motor humming but get no fluid, you could have a clog, a frozen line, or a cracked hose. A good test is to disconnect the hose from the pump and activate it briefly. If fluid shoots out, the pump is working, and the blockage is further down the line.
Are there any recalls for the windshield washer pump on the Subaru Forester?
No. While there were recalls for the windshield wiper motor on some other Subaru models around this time due to an overheating risk, there are no active recalls or TSBs specifically for the windshield washer pump on the 2006-2014 Forester.
Can I just use water in my washer fluid reservoir?
It is not recommended. Using only water can lead to algae or bacterial growth that clogs the system. More importantly, water can freeze in cold weather, which can crack the reservoir, the hoses, and the washer pump itself, leading to a much more expensive repair. Always use a proper windshield washer fluid rated for the temperatures in your area.
