Water neck sensors thread pitch for plugs

[Zrain25]

I'm deleting most of the sensors except for the ecu temp gauge any one know where I can fine the thread pitch for the other sensor ports so I can plug them

They are NPT I do know that but I cant remember size though

There's been a few threads on this before, but they are not NPT and not BSPT, they are metric non-tapered thread. Most are M16x1.5, the big BVSV is something else (still unsure).

I bought some NPT bungs and they were way too loose but did thread in. Bought BSPT, they all leaked, even with teflon tape. Bought metric bungs, no leaking and a snug fit.

The lowest one and ones on the T-stat housing are 3/8 BSPT
The ECU sensor is m12x1.25
CSI Timer is m16x1.5

Ok so I found the 3/8 pretty easily I'm ha wing trouble finding a m12 X 1.25 plug any one know a good place to find them

There are plenty around here, and have a website if there are not any close to you. You can also try the little mom and pop hardware stores, big box stores usually dont carry this size, but the small places just might.

Report back with what size actually fits and doesn't leak. m12 seems too small, and I have my notes saying m16x1.5 fit.

I have 3x 3/8 BSPT plugs in the t-stat housing now and they don't leak. And I was mistaken m12x1.25 is the ECU coolant temp sensor, m16x1.5 is the cold start timer switch(edited post), and the coolant line to the turbo is 1/4 BSPT

Ahh, I have an m16x1.5 in the cold start timer switch, a/c fan switch and aux fan switch sensors, they are all the same.

Is the BVSV 3/8 BSPT or is it some other vague thread?
