Although I have not removed a KS with coolant in the engine I will try it
this time. The plan is to raise the car as high as possible in the front and
carefully remove the KS and have my other hand ready to plug a finger in
the hole as quick as possible. The trick will be to quickly get the new KS
into place and start threading. I'll keep some paper towels in the area for
the spillage and hopefully won't lose more than a cup.

good luck. I know it can look anything but gracefull when you try to get the sensor in the hole quick enough to avoid spilling. I like how you say "area for the spillage...." you make it sound like the Exxon valdez tanker accident!

Re: Changing Knock Sensor..Have few questions

I just changed the knock sensor and it went very smoothly. I have a
convertible so I had to remove the small brace and worked on each
side of the crossover pipe (I have stock manifolds). I would guess that
less than 4 oz of coolant was lost. Much better than I expected.
