Changed Coolant Temp Sensor

[Foeux]

So, guided by the numerous UK and US threads on the benefits of changing coolant temp sensors, I decided to do mine.

 

Would the performance increase? Would it stop the bugger running rich the whole time? Would it be impossibly difficult?

 

It took maybe 45 mins total, including a cuppa. It is frustrating how much has to come off to get to the sensor. I tried to cheat but soon realised there were no short cuts. With everything off, a deep 19mm was all that was needed. No coolant was lost and the only fumble was dropping the old copper washer and carefully placing the new one.

 

The sensor that came out was grubby but not visibly damaged. Everything went back easily enough and the car started a treat. Since doing that it has done 200 miles and I can report that: It no longer runs rich once warm. It reaches idle RPM faster. It has perhaps filled out the mid-range a little. It no longer does the juddery thing it used to do when coming off mild throttle.

 

In short, it is easy to do and cured rich running.
