How to Service and Replace the Air Inject Check Valve on Bank 2 on GMC Jimmy?

Raising the vehicle marks the first step for Air Inject Check Valve/Pipe replacement on Bank 2. Steering linkage shield and AIR shield removal can be omitted from the 2WD vehicle repair tasks but 4WD vehicles require only the AIR shield to stay in place. Well holders that fix the AIR shield need removal in addition to removing the complete AIR shield system. To begin the installation unfasten both the steering linkage shield retaining bolts alongside the steering linkage shield retaining bolts. Start by taking out bolts from the reactor pipe assembly before removing both the assembly with gasket and the assembly itself. You can disconnect the reactor pipe assembly from the reactor pipes by unlatching spring clamps only when replacing the check valve. It is possible to separate the check valve from the reactor pipe by both releasing the spring clamp while loosening the pipe locknut. To install the equipment connect the reactor pipe with check valve via spring clamp application followed by pipe locknut torquing up to 10 N.m (89 lb in). Clean all debris and carbon buildup from the mounting surface because it affects both emissions and vehicle driveability. Fasten the reactor pipe with a gasket before securing the reactor pipe assembly bolts to 25 N.m (18 lb ft) tension while tightening the reactor pipe assembly retainer bolt to 40 N.m (30 lb ft). The reactor pipe assembly requires connection to reactor pipes through spring clamp installation. The installation of steering linkage shield and AIR shield should be omitted for 2WD vehicles but all 4WD vehicles should exclude the AIR shield during assembly. Position the AIR shield properly before installing mounting bolts that need to be tightened to 33 N.m (24 lb ft). Secure the steering linkage shield into position by installing its mounting bolts then tighten them to 33 N.m (24 lb ft). Finally, lower the vehicle.

Q: How to Service and Replace the Air Inject Check Valve on Bank 2 on GMC Jimmy?
A: Raising the vehicle marks the first step for Air Inject Check Valve/Pipe replacement on Bank 2. Steering linkage shield and AIR shield removal can be omitted from the 2WD vehicle repair tasks but 4WD vehicles require only the AIR shield to stay in place. Well holders that fix the AIR shield need removal in addition to removing the complete AIR shield system. To begin the installation unfasten both the steering linkage shield retaining bolts alongside the steering linkage shield retaining bolts. Start by taking out bolts from the reactor pipe assembly before removing both the assembly with gasket and the assembly itself. You can disconnect the reactor pipe assembly from the reactor pipes by unlatching spring clamps only when replacing the check valve. It is possible to separate the check valve from the reactor pipe by both releasing the spring clamp while loosening the pipe locknut. To install the equipment connect the reactor pipe with check valve via spring clamp application followed by pipe locknut torquing up to 10 N.m (89 lb in). Clean all debris and carbon buildup from the mounting surface because it affects both emissions and vehicle driveability. Fasten the reactor pipe with a gasket before securing the reactor pipe assembly bolts to 25 N.m (18 lb ft) tension while tightening the reactor pipe assembly retainer bolt to 40 N.m (30 lb ft). The reactor pipe assembly requires connection to reactor pipes through spring clamp installation. The installation of steering linkage shield and AIR shield should be omitted for 2WD vehicles but all 4WD vehicles should exclude the AIR shield during assembly. Position the AIR shield properly before installing mounting bolts that need to be tightened to 33 N.m (24 lb ft). Secure the steering linkage shield into position by installing its mounting bolts then tighten them to 33 N.m (24 lb ft). Finally, lower the vehicle.
