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

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.

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.
