Front windshield washer hose diagram/sizing

[mc813]

Woke up to the front washer nozzles not working on my '19 4Runner. Thought maybe a connection has slipped off but when looking around and tugging on the hoses I realized there was no tension on the hose running from the underside of the hood down into the passenger front wheel well. Pulled it up and it's either been chewed through or rubbed against something.

Limited by time right now so don't have a chance to pull the wheel off, fender liner and all that fun stuff but was wondering if anyone knows of a diagram that shows the hose routing or what size replacement hose I should be looking to get?

My daughter had her washer hoses chewed -- twice -- by critters. The hose can be hard to replace if it snakes behind panels or other stuff.

You can get replacement hose from any auto parts store. Just take a piece of what you have to get the right size.

The only problem is that Toyota used some connections between pieces that are part of the hose. You will need to improvise with connectors from the auto parts store.

For anyone reading this in the future, first off I’m sorry for what you’re going through and know how you feel. Why the designers couldn’t run it straight into the engine bay instead of going through the fender for all of 1’ I’ll never understand.

I was able to reconnect the hose using a washer fluid hose kit from Amazon. I removed the front passenger wheel, the Phillips head screws holding the liner to the fender flare, and broke off one of the fender liner fasteners (see pic below, the fender liner tab I broke off is replaced with a new push tab for now until I can get to Toyota to get the proper fastener). I was able to get a light between the fender liner and fender flare and see the hose I fished down from the hole it runs into from the hood. Then I squeezed my hand between the fender liner and fender and was able to grab the excess hose and push it from inside the fender through the grommet into the engine bay and reconnect.

Since it seems like it was abrasion at the grommet as opposed to something chewing the washer line I cut open a piece of larger rubber tubing and wrapped it around the washer line where it runs through the grommet and used electrical tape to secure it to the tubing so it wouldn’t shift.
