1992 B230F Temperature Gauge Sender

[AlexO]

Chaps,

My temperature gauge ceased working a while ago and I can't seem to source a replacement that fits. I can find generic replacements but they all seem to be too long or have too many threads so they don't sit flush with the head/block when tight and then don't work. As ever, the internet is providing a great mix of confusing information on this so could somebody please:

A) Confirm that the temperature guage sender is the single wire sensor under the intake manifold under intake runners 2/3 so I know I'm changing the right sensor

B) The part number for this part so I can go hunting. It's for a 1992 B230F if this makes any difference.

Apologies if this is a duplication of effort but I've been researching this for quite some time with no luck.

Thanks,

Alex
