Three varieties of oil filter flanges exist on the VR6 motor. Mk3 VR6 models have 3 senders - a stock temperature sender and 2 stock pressure senders. Early mk4 VR6 models have a stock oil pressure sender and a blank plug. Many newer VR6 oil filter flanges have only a stock oil pressure sender. All stock sending units have M10x1 threads. Sender installation information differs greatly between the three known VR6 oil filter flanges.

Mk3 VR6 Oil Filter Flange
The mk3 VR6 oil filter flange has 3 available ports, all filled with oem sending units. The front two sending units are pressure and the rear sending unit is temperature. To measure oil pressure you will need to use our Oil Pressure Relocation Kit, part # 42-008. Our kit will allow you to install both the SW 1/8" NPT oil pressure sender and an OEM oil pressure sender remotely. The oil pressure relocation kit will take the place of a stock oil pressure sender. The stock sender will now be located aside the SW sender 12" away from the oil filter flange where sufficient room exists.

Unfortunately there is no easy location to measure oil temperature on the mk3 VR6 motor. SW's temperature sender uses 1/8" NPT threads which are not compatible with any of the M10x1 ports on the VR6 oil filter flange. Typically we would recommend our Universal Drain Plug Adaptor, however the design of the VR6 oil pan points the drain plug at an angle which would be detrimental to this adaptor setup - especially when lowered.

Early mk4 VR6 Oil Filter Flanges
An early VR6 oil filter flange will reveal a blank plug located aside the stock oil pressure sender, #9 as shown below. This blank plug is an excellent location to measure oil pressure. Simply use our M10x1 - 1/8" NPT Adaptor to install the 1/8" NPT SW sender in the empty port.

To measure oil temperature an adaptor must be used to replace the oil drain plug. SW's temperature sender uses 1/8" NPT threads which are not compatible with any blank plugs on the oil filter flange. Simply use our Universal Oil Temp Adaptor, part # 42-908 to install the SW sender in the oil pan.

Late mk4 VR6 Oil Filter Flanges
Late VR6 oil filter flanges do not have the empty plug. In order to measure oil pressure you will need to use our Oil Pressure Relocation Kit, part # 42-008. Our kit will allow you to install both the SW 1/8" NPT oil pressure sender and an OEM oil pressure sender remotely. The oil pressure relocation kit will take the place of a stock oil pressure sender #9. The stock sender will now be located aside the SW sender 12" away from the oil filter flange where sufficient room exists.

To measure oil temperature an adaptor must be used to replace the oil drain plug. Simply use our Universal Oil Temp Adaptor, part # 42-908 to install the SW sender in the oil pan.

What about the 24v VR6?
The 24v VR6 uses the later oil filter flange. No blank plug is available for measuring oil temperature. Follow the instructions above for late VR6 oil filter flanges to install oil senders on a 24v VR6.

Tools Required:
24mm Deep Socket
5mm Hex Wrench

When installing oil sending units it is important to maintain a ground between the sending unit and the engine block. Ground is normally maintained in the threads of the sending unit. Use only 1 wrap of teflon tape on sender threads to assure no leaks or loss of ground.
