I have a 99 c/k GMC not the new style 99, with a 7.4 engine i have a factory shop manual but i am a little unclear on how to remove the lines from the block fittings there are these red plastic pieces on the lines pushed up to the hex fittings on the block, do you pull these pieces back to reveale a retaing ring to get the lines out of the block fittings? Thanks for your help. The other ends of the lines go to the radiator with regular spin nuts.

  This is a really late reply but I just found this thread. They won't sell the hinges. I've gone 7 rounds with them. Their solution is to buy a new cover. I'm about to buy a new cover and it won't be a Bakflip. It also won't be from realtruck.com.

  Yes, and also pulling heavy trailers or a large camper up steep grades as well as descending grades such as the more rustic off road camping locations and using engine braking with that low gearing as well as soft ground can just suck the power . I realize pickups these days tend to have an over all lower first gear ratio compared to automatic transmission pickups from years back so that has helped a lot in its ability in high range but there comes a point if in four wheel drive the torque runs out at the wheels, certainly with a gas engine. They don't put two speed transfer cases on pickups for a cool factor, they have a function if one needs that massive torque to the wheels that high range can't deliver.

  Notes 7/18/2026 3,400 miles on this batch of Mobil 1 Euro 5W40 since the GDI pump replacement. Alcohol runs very clean when ring seal is tight and the sump isn't getting hosed with fuel. Checked oil level at fill up today as is my practice and grabbed a white Kleenex to look at the color. What color? I was going to change it but.....
