Having trouble finding this replacement part, the connector that goes to the water temp sensor in the head, near the water neck. The connector cracked and so I need a new replacement. I did find these online which appear to work in some applications even the k series, which is interesting because they are for American cars.

Essentially what is needed is shown below, the water temp sensor for b series looks similar to that of the k series shown below. The connector is just a simple push on cylindrical style, there is no retaining clip.

If anybody has any ideas or knows the oem part number please let me know thanks! If I can’t figure it out I’ll probably pick up the 90 degree style boot connector that is shown below, one user reported this style worked for their k series.

 

The factory OE Honda part number is: 37750-PH2-014

 

It's a 4mm Bullet. These are what I use.

 

Sorry OP... apparently I didn't read your original post thoroughly... I thought you were looking for the sensor part number, but you NEED the connector for the tip of the sensor. This cannot be purchased from Honda, but spAdam had posted an excellent suggestion above. Good Luck.

 

Thanks guys!!!

The part I ordered worked, here’s the new and old. Didn’t know the size, just guessed and ordered this and it fits.
