Title: pyrometer probe
Post by: w1004thw on March 13, 2026, 12:49:42 pm

Where and how do you place a pyrometer probe in the 1.6 td exhaust?  I am thinking of placing it before the turbo, but where does it go, or where is the best pace, and how do you do it? 
Thanks

Mine is mounted about 2 inches past the turbo exhaust flange.  On the pipe with a bung welded on there that the EGT probe inserts into.  Some sensors come with a strap-like thing that you just drill a hole into the exhaust pipe and slip it in, and then tighten the strap to hold it in place.  I think there was some way to seal it off to keep the exhaust in the pipe and out of the engine bay.  The best mount is threaded.

I probably shouldn't have but I put it through the bolt hole on one of mine.
But it never caused a problem:
