#6 Re: Thread and hose barb size

Neither, it is metric. You can measure the hole, then go to a hardware store or bolt store and get one the same size

The A12 is all metric except the early flywheel bolts and the oil sender threads as far as I know

As you can see they are taper threads. The hose barb is 17.5mm over 16mm O.D. tube (for 13 mm I.D. hose)

The front one is the temperature sender (or as Nissan calls it the "thermal transmitter"

M16 x 1.5 threads

The original is a two-piece type with a threaded collar
newer versions are a one-piece type with the threads cut into the transmitter

Hi Guys.
Could someone please tell me what both the thread and hose barb sizes are for the two fittings the bolt into the head at the two points indicated? I know the rear one is 90degrees while the front is straight but if someone could shed some light that would be great.
