Boxster 987 washer fluid low warning light on ?

[jim_hoyland]

What is the main cause of the warning light despite having water in thr tank ?

[Loren]

A bad tank sensor is fairly common.

[jim_hoyland]

And I should be able to replace myself ?

 

[JFP in PA]

Yes

[jim_hoyland]

I saw several listed; can you pinpoint the part number?

the car is a 2096. 987

 

[Loren]

955 628 105 00  Water level switch - US MSRP $22.10  (item 11)

 

[jim_hoyland]

Thank you. I’ll get an order in today. 

[jim_hoyland]

Orders in: wondering how easy replacing the sensor is goons bee.

watched a video, but not clear to me

[Loren]

There is just a sealing washer around it and the electrical connection.

When you pull the old one out washer fluid will leak out so push the new one in right away. Then transfer the electrical connector. Done.

[jim_hoyland]

Got the part…

[Jim Long]

How did it go Jim? Was it easier for you than expected?

[jim_hoyland]

As soon as the switch arrived, the warning light went out. Some posts suggest the switch can act erratically.

keeping an eye on the situation.

Still haven’t installed the sensor. Ran a test: I filled the reservoir to the top and used the windshield washers until the warning light came back on. Then refilled with a measured volume. The reservoir took 66 oz to refill; the warning light went back out.

My next test is to not use the washers for awhile, say a week or a month. Then check the level again and determine whether the reservoir leaks when driving.

Otherwise, now I’m going to tackle cleaning the top

[Jim Long]

Did you re-check your washer level? Did you find that it was indeed leaking?

 

How did the top cleaning go?

[jim_hoyland]

I will check this weekend. I didn’t use the washer and the light hasn’t returned.

Will update 

[jim_hoyland]

The washers were not used for approx 1 month. Today, I filled the washer tank again to Full. It took about 28 oz.

I am assuming the tank got filled at the start of my experiment. 
There is no signs of water on my gsrxge floor.

I think I’ll siphon out the water into quart bottles and see when thy he alert comes on

[Jim Long]

Ok! Great news so far! I like the siphon idea too...

[jim_hoyland]

Update: I tried to rig up a siphon to start the draining in order to detect when the warning comes on. Well, the washer reservoir will not allow a tube to be inserted.

             So, I'll resume using the washers and when the light comes on; I'll measure the amount needed to fill.

Question: What is the capacity of the washer reservoir ? ; My car is an '06 987 

[Jim Long]

I understand the windshield washer tank capacity to be about 6 liters.

Look up Porsche Boxster Cayman specifications, engine oil capacity, spark plug gap, safety rating, fuel consumption, transmission, and light bulb sizes.
