Hi all,
I am going to replace it and was just wondering if I should expect any coolant leak while doing the job?
Thanks, /MM
Changing knock sensor on a 1999 Legacy 2.2L

I replaced the knock sensor on my son's '99 Impreza (with 2.5L engine) and it's located in the intake manifold - so no coolant issues. Should be the same for you, I would think.

Not at all. Just unscrew it and install new one.
Thanks so much to you and Dan for answering!
Just did this myself on a 95 Legacy. No coolant leak - it's just bolted onto the top of the engine.
You don't have to remove the intake manifold either, like it says to in the service manual. A 6" socket extender is enough to reach the nut and anyone with normal/slender fingers should be able to reach the connector.
