2013 GMC Sierra 1500 4x4 w/5.3L
Checking the oil, etc., today. Power steering pump has 0 fluid in it. Was running and steering fine on a 100 mile trip we just got back from. Absolutely no signs of a leak on top or underneath engine. I’ll refill with fluid and check it again after a short trip.
What fluid does everyone use for topping off? OEM or aftermarket fluid? Preston’s makes a fluid that’s compatible, or I can just wait until Monday and get taken at the local dealer. Any recommendations for aftermarket PS fluid?
I don’t intend to flush and refill unless I have a leak I haven’t found.
