Lambda Sensor Spanner Size?

[PatHeald]

What size of box spanner do I need to procure, then cannibalise, to get the Lambda Sensors out?

Cheers

Same size as a plug spanner.

Incidentally, after slotting a box spanner and then finding it couldn't take the torque, I found that I could get the sensor out with an ordinary 1/2" drive socket. I pushed the pins out of the plug, the wires and seal pushed through the hole in the socket, the body of the lambda sensor (just, by a fraction) fits through the hole too, and the socket goes on far enough to engage the hexagonal base of the sensor. Padded mole grips on the outside of the socket have enough grip to undo the sensor.

Worth a try bfore you wreck a perfectly good box spanner.

RV8 sized plug spanner, I assume?

Correct, I meant the same size as the spark plug spanner for your Griffith. Incidentally, if you take this approach remember to make a carefull note of which wire goes in which hole in the connector housing so you can reassemble the connector afterwards.

I managed to butcher a 12mm spark-plug socket (as in a M12 spark plug thread). The hex was 18mm across flats. Torque-up is 18-23 Nm

When I say butcher I mean the hole through the middle of the socket had to be opened out to ~1/2" to go over the top of the sensor (~12mm). I did this with a stone on the dremel.

I bought one from German Swedish Car parts (GSF) for £8.

Not too bad really.
