Q: How to service and repair the air cleaner fresh air hose on GMC Canyon?
A: Servicing and repairing the air cleaner fresh air duct/hose, start by disassembling the air cleaner outlet duct and taking off the atmospheric vent hose from the air cleaner resonator. Screw the air cleaner resonator bolts and disengage the air cleaner resonator outlet duct clamp. Lift upwards while prying the crankcase ventilation hose off the camshaft cover and the outlet duct off the Throttle Body, and pull out that assembly from the engine. For installation, orient the outlet duct over the Throttle Body assembly and the crankcase ventilation hose to the camshaft cover port. Tie the bolts for the air cleaner outlet resonator to the captured nuts on the camshaft cover so that the outlet duct is correctly installed to the Throttle Body assembly and not rolled under. Install the air cleaner resonator outlet duct clamp correctly and tighten it to 6 n.m (53 lb in). Install the 2 air cleaner outlet resonator to camshaft cover bolts and tighten them to 6 n.m (53 lb in). Lastly, attach the atmospheric vent hose to the air cleaner resonator, and fit the air cleaner outlet duct.
Q: How to service and repair the air cleaner fresh air hose and replace the air cleaner outlet resonator on GMC Sierra 1500?
A: Begin air cleaner fresh air duct repair by disconnecting the positive crankcase ventilation hose from the air cleaner outlet resonator. The service starts with unclipping the air cleaner outlet resonator at its connection points to both the Throttle Body and mass air flow (MAF)/intake air temperature (IAT) sensor. Both the Throttle Body and maf/iat sensor require the removal of the air cleaner outlet resonator. When installing the air cleaner outlet resonator place it onto the maf/iat sensor and Throttle Body while achieving 4 nm (35 lb in) torque on both the Throttle Body clamp and maf/iat sensor clamp. Reattach the pcv hose to the air cleaner outlet resonator.
