Here is a tech tip that Dave Hagey, as he was working in his shop, found to be very helpful for owners of Cummins-powered second-generation Dodges: swapping a power steering dipstick fill tube from a late 1980s-early 1990s 4.3L Chevrolet Blazer or Oldsmobile Bravada. The power steering pumps on the Dodges are quite prone to leaks, among other problems. Also, the second-generation trucks don’t have the most accessible filler points on their power steering pumps. That creates a huge headache when the power steering fluid has to get refilled.
Simply refilling your power steering fluid shouldn’t be such a hassle, and it sure doesn’t have to be. That’s all thanks to this handy filler neck from the older gas-powered GM SUVs. It installs quite easily into the power steering pumps on the trucks, and it makes checking and filling the pumps easier and less messy. “I have many more photos on my Facebook page, Dave T. Hagey, and you may be able to see them better,” Hagey says. “I even use this on my Buick V6-powered Scout.”
