  Q: How to replace the spark plugs in an engine on Chevrolet Venture?

  A:

  Checking for engine temperature must occur first before starting the Spark Plug replacement process to protect Cylinder Head threads from damage. The Spark Plug recess area requires cleaning to prevent contamination and the specified spark plugs alone should be used on the vehicle. Switch off the vehicle ignition before starting the process. The right bank (rear) engine spark plugs need replacement but first remove the windshield wiper module cover and actuate the engine using the engine tilt strap (J41131). Start by disconnecting the throttle body air inlet duct followed by applying the park brake and shifting the transaxle into neutral position. The installation requires removal of the engine mount strut bolts to attain access for the engine mount struts swing. Fasten the engine tilt strap (J41131) before pulling the engine forward for rotation then tightening the strap. Near the end of this operation remove Spark Plug Wires together with spark plugs that exist on the engine. New and reconditioned spark plugs need gap inspection by round wire feeler gauge for compliance to specifications. Use a thread chaser to install the spark plugs which should smoothly enter the Cylinder Head until they reach full depth; thread chaser intensity depends on the results. The initial installation requires torque to 20 nm (15 lb ft) while you should torque them to 15 nm (11 lb ft) during reinstallation. Put on Spark Plug Wires then restore engine alignment before you place back the windshield wiper module cover.

  Q: How to service and repair spark plugs in an engine on Chevrolet Venture?

  A:

  Begin Spark Plug servicing and repair only when the engine temperature has lowered because hot engines could cause threads to seize or damage the Cylinder Head. Clean the Spark Plug recess section thoroughly to stop dirt entering the Cylinder Head because it will contaminate the threads to such a degree that new spark plugs may fail to sit properly. The vehicle needs spark plugs according to manufacturer specifications because different heat levels in plugs may result in severe engine damage. Before initiating replace a black plastic tarp over the hood to safeguard from water and debris. To access the rear spark plugs maintenance requires a windshield wiper module removal followed by engine rotation for service purposes. Following wiper module removal the engine service access requires you to take down both the Spark Plug Wires and engine spark plugs. Examine the new and reconditioned spark plugs with a round wire feeler gauge before installation since handling may have altered the pre-set gap which requires checking to meet specifications to prevent engine dysfunction or damage. Install the spark plugs into the engine by letting the threads easily join the Cylinder Head before achieving full seat depth; employ a thread chaser to clean any threads that need attention. The proper torque level should be followed during Spark Plug installation by using 15 n.m (11 lb ft) torque to avoid heating issues and exhaust gas leakage and thread destruction. The last step includes wire installation of Spark Plug connectors while engine right bank plug replacement demands returning components to their correct position and reinstalling wiper module attachments.
