To remove and install the front and rear washer reservoir, raise the rear of the truck and secure it on jack stands, and then disconnect the negative battery cable and the reservoir electrical connector. Then, unscrew the fluid tube from the washer motor; if it is overly tense do not attempt to force it, use a heat gun to loosen it or cut the tube at the motor end if more space cannot be obtained. Then, unlock the identifying bolts of the reservoir and pull it out of the bracket. As for installation, the processes are opposite; just before tightening the washer tube to the motor nipple, put some petroleum jelly inside it. Be sure that the check valve of the washer fluid line is installed in the proper direction to avoid problems.
