I have a '72 1.7 that has a few problems. I have a 0 280 130 012 Cylinder Head Temperature Sensor that I would like to install but can't seem to figure out how.
It's near the #3 Cylinder, correct? Do I have to remove the intake? This newbie is stumped! (IMG:style_emoticons/default/hissyfit.gif) Can someone help me?? Thanks in advance! Keoni914 |

You don't have to remove the intake. You do have to find the correct hole in the engine tin and make sure the sensor is there.
You can thread a deep-well 13mm socket on the wire, fold up the wire in the socket, and remove that way. You can also strip the threads on the sensor that way. (IMG:style_emoticons/default/sad.gif) Big PITA, very very hard to repair without dropping the engine. A specialty tool that helps the R&R is a "tubular spanner", which is a hex-shaped metal tube that fits over the sensor and that you put a wrench over the other end. Or you can knock one corner off of a short extension so that it allows room for the sensor's wire when you plug the extension into the back of the 13mm socket. Whatever you use, hose it down with a lot of penetrating oil for a couple of days first. (WD-40 is not a penetrating oil; PB Blaster and Aero Kroyl are.) And pray. --DD |

Dave thanks but...
Oh Oh so your saying getting the old out might be a PITA? From my perspective the hole looks like it's right in front of the intake, way too close for a deep socket. Am I looking in the right place? Anybody have photos? Darn, nothing is easy on a Teener, huh?? (IMG:style_emoticons/default/sawzall-smiley.gif) Keoni914 |

Deep socket with an extension will fit.

I never found getting it out to be that difficult. Getting it out without the threads coming with it can be a challenge, and trying to install a time-sert or other thread repair without dropping the motor.... That is the true PITA!
And the deep-well socket with an extension works well. You may even be able to use a non-deep socket if you use an extension with a corner ground off to make room for the wire. --DD |

This is what I did two years ago. I took the runners off and it was easy enough to get to. As I said in the post it is a little ways in the tin. I used a deep well 13mm socket. I ground off the edge of a cheap 2in extension so I could pull the wire thru. Beyond that it is not too bad. Look for the wire that goes into the tin thru a rubber grommet under the fuel injector intake runner on the passenger side.
