    pretty sure it will respond fast enough. The specific heat capacity of water is about 4 times greater than rubber. So if the cooling water is heating up, the rubber will heat up just as fast. The rubber is @ 3mm thick so the surface temp will be slightly less than the internal temp. However if I wrap the sensor onto the rubber hose with amalgamating tape, the sensor is effectively submerged into the rubber hose, and not exposed to the ambient air cooling it down. Should be good enough and plenty fast enough to indicate a developing issue. And I still have the over temp sensor/alarm indicators and I know they work. (2 new impellers please!)

    Makes sense and no new holes

    Well the spare bolt hole in the d4 inlet manifold is not m18, don't know exactly what size it is but it could be 10mm. 12mm or 14mm.

    So I couldn't fit the wireless pressure gauge. Oh well back to the drawing board.

    You can get the 1/8 npt adapters in any M size you need.

    Or get a M20 to M whatever adapter.

    What size socket goes on the current blanking bolt? Although not always....I have often figured out the bolt size based on which socket went on it.

    I owe you a beer!

    It was an Allen key head, either 6 or 8mm. I'm going to take the bolt out again and measure it, but I'm guessing it was m10.

    note M10X1.0 is NOT the standard M10 bolt, X1.0 is narrower pitch.
    Having said that all oil/air threads I have on my IVECOs are M10X1.0...

    Right I've measured it and I'm reasonably sure it's M12, but what I can't be sure of is the pitch, so I'm going for it being a standard coarse pitch (1,75)

    It’ll be fine pitch now
