Do not use Teflon tape on the threads. It will interfere with the sender ground. Sender threads are tapered pipe threads and are self-sealing.
Temperature senders are most accurate when installed in the aftermarket intake manifold. It is also acceptable to use the OEM engine manufacturing
specified location. Installing in the cylinder head can cause high readings due to the exhaust manifold heat. Do not use tee adapters, reducing, or angle
adapters for temperature sender since the sender tip or bulb will not be immersed in the water flow.
Senders can be tested with an ohmmeter that measure from 10 to 2,000 ohms. Connect the positive lead from the tester to the sender terminal and the
negative lead to a good ground. The following readings will occur if the sender is operating property.
Temperature Sender
Cold
- 700 ohms
Hot (250 degrees)
- 22 ohms
Pressure Sender
Engine Off
- 10 ohms
Engine running 40 psi = 105 ohms; 60 psi = 152 ohms

Tools/Items Needed to Complete Installation:
3/4" (18mm) wrench
Pliers or other crimping tool (optional)
Wire cutters/stripper
a length of 16-gauge insulated wire
1/4" ring terminal (optional)
I. Installation the VDO Universal Pressure Sender
There are three bushings included in this kit – one is 1/4" – 18 NPT,
another is 3/8" – 18 NPT, and third is 1/2"-14 NPT. The fitting on the
sender itself is 1/8" – 18 NPT. Decide which bushing if any, you will
need to adapt the sender to the opening in the engine block.
Discard the rest, or save them for use later in another project. But
be aware that you will have left over bushing after you complete
your installation.
1. Select a location for mounting the pressure sender.
2. Take the correct bushing, if needed, and screw it tightly onto the
sender with your finders.
3. Clean the opening in he engine block where the sender unit will
be inserted. Clean threads are absolutely necessary if a good
ground and reliable operation are to be obtained.
4. Screw the sender unit finger-tight into the engine block.
5. Use a 3/4" (18mm) wrench to crank the sender into the block. As
you crank, you will tighten the bushing into the block and the sender
into the bushing. Keep tightening until the sender assembly is snug.
Do not over tighten. The sender is self-sealing, and will not leak.

Proper Wiring Between Gauge and Pressure Sender
II. Wiring the VDO Universal Pressure Sender
1. Either run a new wire to the pressure gauge or find
the existing wire if a pressure gauge is ready to be
installed.
2. Crimp a ring terminal onto the sender end of wire.
3. Attached the ring terminal to the terminal on the
sender.
4. Make sure the other end of the signal wire is
properly connected to the pressure gauge (see
diagram C)
5. Turn on the power, and make sure the gauge is
working, if it isn't recheck your wiring. (See
"Troubleshooting" below.)
