Using this adapter is easy. First, find the extra 1/2NPT port on your aftermarket oil pan. Then, screw the adapter into this port. Next, attach your aftermarket temperature sensor with 1/8PT threads to the adapter. Before you buy, make sure this adapter is compatible with your vehicle. You might need to make a few small changes to install it correctly. To keep it working well, check the connections regularly to ensure they're tight. If you notice any leaks, tighten the parts or replace the adapter if necessary.
