Oil Pressure Sending Unit

To change the sensor or switch of the engine oil pressure, first, turn off the engine cover. Remove the engine oil pressure sensor gauge electrical connector and then use a wrench to hold the engine oil pressure gauge sensor fitting as well. Pull out the engine oil pressure gauge sensor with the Oil Pressure Switch Socket (J41712) with the attention to the position of the fitting before taking it out. Take out sensor fitting for engine oil pressure if required. When installing, if the fitting was removed, make sure to put it back and tighten to 15 Nm (11 ft. lbs), to not loosen or over-tightening it one turn to align. Install the Engine Oil Pressure Gauge Sensor, while gripping the fitting with the wrench to avoid any rotations, and tighten the sensor using the Oil Pressure Switch Socket (J41712) to the tightness of 30 Nm (22 ft. lbs.). Lastly, reconnect the engine oil pressure gauge sensor electrical connector and put back on the engine cover.

Engine cover removal marks the first step before moving forward with engine oil pressure switch replacement. Begin by disconnecting the electrical connector of the engine oil pressure gauge switch before grasping the fitting with a wrench. Use the Oil Pressure Switch Socket (J 41712) to detach the engine oil pressure gauge switch while tracking the fitting position before removal. The installation requires switch fitting removal if needed. The fitting installation requires 15 Nm (11 ft. lbs.) torque using a one-turn rule to achieve proper fitting alignment when switch installation occurs after removal of the fitting. Tighten the engine oil pressure gauge switch to 30 Nm (22 ft. lbs.) using the Oil Pressure Switch Socket (J 41712) but keep the fitting stable with a wrench to avoid rotation. Plug both ends on the engine oil pressure gauge switch electrical connector before returning the engine cover into place.

Engine cover removal together with the air cleaner assembly is a starting point toward replacing the engine Oil Pressure Switch. Use a wrench to hold the eop gauge switch fitting after disconnecting the electrical connector from the engine oil pressure (EOP) gauge switch. Manufacturer j 41712 provides the required Oil Pressure Switch socket to remove the eop gauge switch by first paying attention to the eop gauge switch fitting alignment. To continue, remove the eop switch fitting if needed. Sealant gm p/n 12346004 or an equivalent application should cover the eop switch fitting threads before installation at 15 n.m (11 lb ft) torque while avoiding 359 degrees fitting rotation after the initial torque setting. Start with the eop switch fitting at 50 degrees from the centerline before putting the eop switch into position. Apply a wrench to stabilize the eop switch fitting before using the Oil Pressure Switch socket (J 41712) to apply torque at 30 n.m (22 lb ft). Reestablish the electrical connection followed by installing the engine cover and the air cleaner assembly.

The first step to replace the engine oil pressure switch requires removal of the engine sight shield. First disconnect the oil pressure switch electrical connector then utilize the Oil Pressure Switch Socket (J 41712) to extract the switch. Use GM U.S. P/N 12346004 or Canadian P/N 10953480 or a similar aftermarket sealant on the threads of the new oil pressure switch before installing it with the Oil Pressure Switch Socket (J 41712) until it reaches 30 Nm torque (22 foot lbs). Install the engine sight shield while reattaching the oil pressure switch electrical connector.

To change the engine Oil Pressure Switch first, you will need to gather the tools such as: Oil Pressure Switch socket (J 41712). Start by cleaning the surrounding of the switch and Distributor to avoid debris from getting in the engine. Unplug the connector for the engine Oil Pressure Switch, and then remove the Distributor from the system. Remove the engine Oil Pressure Switch using the Oil Pressure Switch socket (J 41712) and remember the alignment in the fitting before removing. If necessary, take off the engine Oil Pressure Switch fitting. Seal the threads of the fitting or the engine Oil Pressure Switch using sealant gm p/n 12346004 or equivalent. In case the fitting had been taken off, reinstall it and tighten it to 15 nm (11 ft. Lbs.). Next, install the engine Oil Pressure Switch and tighten using the Oil Pressure Switch socket (J 41712) into a torque of 30 nm (22 ft. Lbs). The engine Oil Pressure Switch electrical connector should be reconnected, the Distributor should be reinstalled back on, and at last, the engine oil level should be checked and adjusted.

In order to replace the engine oil pressure switch, remove the engine cover from a vehicle and disconnect the electrical connector from the oil pressure switch. Use the Oil Pressure Switch Socket (J 41712) in order to remove the oil pressure switch from the engine block. For installation, be sure to follow the fastener notice in service precautions, then install the new oil pressure switch to the engine block with the Oil Pressure Switch Socket (J 41712), torquing to 12 Nm (9 ft. lbs). Connect the electrical connector with the oil pressure switch and reassemble the engine cover in the vehicle.

Start your Engine Oil Pressure Sensor or Switch replacement by obtaining these essential tools: Oil Pressure Sensor Socket (J41712). Oil Pressure Sensor Socket (J41712). Lift the engine cover and disconnect the wiring harness of the oil pressure sensor as the first step. The replacement of the oil pressure sensor requires use of an Oil Pressure Sensor Socket (J41712) or an equivalent tool. You should apply GM P/N 12346004 (Canadian P/N 10953480) or an equivalent sealant onto the new oil pressure sensor threads before installation. Use an Oil Pressure Sensor Socket (J41712) along with another equivalent tool to mount the oil pressure sensor afterward tightening it to 20 Nm (15 ft. lbs.). As the last step, reinstall the engine cover after connecting the oil pressure sensor electrical connector.

Replacing the engine oil pressure sensor or switch may require you to gather a range of tools before starting: Oil Pressure Switch Socket (J 41712). Start with removing the engine cover, then you need to disconnect the engine oil pressure sensor gauge electrical connector. Hold the engine oil pressure gauge sensor fitting using a wrench and remove the sensor with the help of the Oil Pressure Switch Socket (J 41712). Mark alignment of the sensor fitting before removal, and if needed take out the fitting. For installation, if the fitting was removed, install it and tighten to 15 Nm (11 ft. lbs.), never to diagonal it more than one turn for alignment. Next, install the engine oil pressure gauge sensor tightening fitting using a wrench and tightening the sensor to 30 Nm (22 ft. lbs.) with an Oil Pressure Switch Socket (J 41712). Lastly, reconnect the engine oil pressure gauge sensor electrical connector and replace the engine cover.

Note the alignment of the fitting before removal, and if necessary, remove the fitting as well.

Hold the engine oil pressure gauge sensor fitting with a wrench and use the Oil Pressure Switch Socket (J 41712) to remove the sensor, noting the alignment of the sensor fitting prior to removal.

First, remove the engine cover.

Disconnect the engine oil pressure sensor gauge electrical connector.

Hold the engine EOP gauge sensor fitting with a wrench and use the Oil Pressure Switch Socket (J 41712) to remove it, noting the alignment of the fitting prior to removal.
