Can you replace the factory head temp sensor with the engine still in the car?
Thanks |

I'll take credit for that tip, I think I'm the source (IMG:style_emoticons/default/smile.gif) The copper washer is important for good heat transfer from the head to the sensor. Hard to understand why they didn't make it captive, considering how it's installed. BTW, in another thread, I reported that for VW applications, there is a spacer that you can put between the CHT and the head. It's about 3/4" long. The idea is that it delays the sensor from being heated up initially when the motor is cold, so that the mixture stays richer for a longer time. Might be an interesting way to fix some warm-up issues. |
