Toyota Corolla Windshield Washer Reservoir

Find and Fix: A Toyota Corolla Windshield Washer Reservoir Troubleshooting Guide

Are you experiencing less visibility on the road? Can't see through the dirt specks and bird droppings splattered on your windshield? Fortunately, a few squirts of washer fluid can help remove those nasty marks and make your windshield spotlessly clean again. To ensure you won't encounter any problems each time you activate the windshield washer spray, you should always check the condition of the reservoir. This plastic tank is where all that blue fluid comes from, so you'll experience little to no spray when it gets damaged. If you think your Toyota Corolla windshield washer reservoir is no longer holding the washer fluid properly, better roll up your sleeves and do some troubleshooting right away. Here's a guide to help you find and fix some washer reservoir problems:

Lack of washer fluid

If the nozzle won't spray out washer fluid, you probably have a cracked or leaking washer reservoir. Tiny cracks usually appear on the reservoir over time as the plastic material becomes brittle and vulnerable to damaging elements. Minor or high-impact collisions near the wheel well where the washer reservoir is located may also break or crack the plastic. Do a quick visual inspection on the reservoir before attempting to repair it. In some cases, the problem may not lie in the reservoir, but in the parts connected to it, such as the nozzle, grommet, hose, and pump. A clogged nozzle, a damaged grommet, a leaking hose, and a defective pump may also prevent the washer fluid from getting out of the reservoir. Check these parts for damage and replace them if necessary. To repair the leaking reservoir, you may apply epoxy over the cracks. If this doesn't do the trick, get a replacement immediately.

Knocking and clunking sounds

If you hear unusual knocking and clunking noises from the engine compartment when going over bumps, it's most likely a loose windshield washer reservoir. The sound it produces is different from a loose metal part; it's more like plastic knocking against the engine compartment. To fix this problem, tighten loose screws and replace missing bolts or damaged seals if necessary. This would help keep your washer reservoir attached to the assembly for a longer period of time.

  • Top Maintenance Tips for Your Toyota Corolla Windshield Washer Reservoir 27 February 2013

    Your Toyota Corolla windshield washer reservoir is just a simple part that requires very little maintenance. As long as it is not cracked, loose, or leaking, your washer fluid is safe and sound. Over time, the plastic material of the washer reservoir may become very brittle and more prone to damage. A web of tiny cracks may appear on the reservoir, causing washer fluid to leak out. To prevent cracks from spreading and breaking the plastic completely, you need to practice proper care and maintenance on the washer reservoir. We've listed a few maintenance tips to keep your reservoir in good condition.


    Patch up tiny cracks.


    You shouldn't ignore tiny cracks. These little monsters will get bigger and create irreparable punctures on the reservoir over time. Once a tiny crack creates a gap on the plastic, washer fluid will start to leak out and the reservoir will be drained of fluid faster than you can say 'windshield.' If the washer fluid indicator on your dashboard keeps lighting up even if you've just replenished the reservoir, then you definitely have a leak in the tank. This can be costly on your part, especially if you keep refilling the reservoir to the brim. To avoid this problem, patch up tiny cracks right away with epoxy. Make sure to let the solution sit on the crack for at least an hour before reattaching the reservoir to the assembly. If the cracks are beyond repair, it's time for you to get a Toyota Corolla windshield washer reservoir replacement.


    Clean the reservoir regularly.


    Cleaning the reservoir regularly will help prevent contaminants from entering the system and clogging the hose or nozzles. It is also a must to flush out old and dirty washer fluid occasionally to prevent debris from getting sprayed onto your windshield. So, before cleaning the reservoir, make sure you drain out the old fluid first. Also, to get rid of stubborn stains inside the reservoir, scrub it thoroughly with a toothbrush and rinse it with water. This will not only remove stains and debris but also calcium buildup and sediment.
