What's this part?


Hi Guys

I've just removed the engine and am stripping off all of the tinware so that I can see what it is missing.

I have attached a photo of some sort of sensor that was screwed into the head above # 1 cylinder. I am sure that it was not connected to the ECU or any Cylinder Head Temp Gauge...can anybody tell me what it is and point me to a website?

Thanks

Regards
Greg

Pull it out and show us the end that screws into the head and can tell you a bit more, but yeah - for my money it'll be a Coolant Temp Sensor that's just been tapped into the head to get Head Temp... very common way of doing things.

100% definite it doesn't normally exist on a Beetle, but may be from a modern VW (I have repurposed a Golf fuel pressure sensor into my aircooled Beetle for example).

Doesn't look like a metric thread tho, so suspect it's a cheapy Chinese generic.

Does it have any markings on the black plastic part... like a part number perhaps ???

Hi guys
It just has a long threaded piece that screws into the head. The only marking is a CI in the body. You can see it in the photo.

it could be a coarse metric thread as used on some japanese cars..

or whitworth if anyone uses it these days???

looks too coarse even for pipe thread...

maybe a very coarse thread so nothing else can be screwed into the hole??

Hi Guys

Here is another photo of the mystery sender.

I can screw on one of the engine mounting stud nuts.

Yup - Coolant Temp Sensor for sure, just being used to get Head Temp (as said - very common).

Unless of course it goes through and the end touches air/oil inside the rocker area... then it'd be measuring oil temp.

:)

I though it was something like that.
