2017 Sierra Washer Fluid Capacity

[Mileguru]

I'd rather not drain my windshield washer fluid to find out the answer. Does any already know how much a 2017 Sierra SLT 6.2L can hold in the washer reservoir? Thank you in advance.

About 1 gallon

My 2010 Sierra will take about 1 Imperial gallon.  The first time I had to fill it I was surprised it took the entire bottle.

Thank you. I thought it would be well over a gallon. Good thing I asked. Working on a methanol injection system and wanted to know what the stock reservoir would hold. Seems like an external tank placed in the spare battery area would be better because a 2 gallon gas can EASILY fits there.

Thank you for the responses. Now it looks like I might have to use the washer fluid tank after all. My new question is, "Does a 2017 Sierra SLT have a low level sensor already built in?"

My guess is of course, yes.
