Q: How to service the EGR Valve without disassembling it on Chevrolet Express 3500?
A:
Service the linear EGR Valve under the condition that disassembly should be avoided since it requires full assembly service. Take note of the exhaust gas recirculation valve position before removal to make sure it does not rotate by 180 degrees. Start by disconnecting the Battery Cable and taking out the air cleaner assembly from its position. Service the EGR Valve by disconnecting its harness connector but keep the linear EGR Valve free from all liquid cleaners or solvents because it is an electrical component that may suffer damage. Detach the EGR Valve to flange bolts and extract the linear EGR Valve unit with its associated flange gasket. Before installing the linear EGR Valve it is necessary to thoroughly clean its gasket surface. Fix the new flange gasket to the linear EGR Valve while closely following the fastener notice. Begin by tightening each of the valve-to-flange bolts to 10 n.m until they reach 89 lb in torque while completing the second step by tightening the bolts to 25 n.m at 18 lb ft torque. The EGR Valve harness connector must be reconnected after reinstalling the air cleaner assembly while completing the process by reconnecting the negative Battery Cable.
Q: How to replace the EGR valve on Chevrolet Express 3500?
A:
Before removing the exhaust gas recirculation (EGR) valve first cut power to the ignition system then eliminate the air cleaner assembly with attention to record the EGR Valve orientation and ensure it remains 180 degrees correct. The user must disconnect the EGR Valve harness but should avoid soaking the linear EGR Valve in any cleaning fluids or solvents because it functions as an electrical component. Detach the EGR Valve to flange attaching bolts by themselves since linear EGR Valve maintenance requires service as an entire assembly. You should delete the linear EGR Valve from its position while also removing the flange gasket for further cleaning of the gasket's surface. Before installation position the new flange gasket before inserting the linear EGR Valve. Firmly mount the valve to its flange until bolts achieve an initial torque of 10 n.m (89 lb in) per bolt before securing them to 25 n.m (18 lb ft) each. Return the EGR Valve harness connector to its place while installing the air cleaner assembly.
