HelloCustomer I am sending you the information from the GM service manual on bleeding the clutch on your truck. This is never a fun job and can drive you nuts sometimes, because it can take forever. I have found that a vacuum bleeder works much better and sometimes even a can of fluid with a pump in it and hooked to the slave cylinder with a rubber hose and forcing the fluid through the system backwards and letting it run out of the master until there is no more air also seems to work better than the factory method. But here it is just in case. Thanks, Bob
Important: Never use fluid that you have bled from a system to fill the reservoir. The fluid may be aerated or contaminated.
Important: Ensure no air is drawn into the clutch system.
