Wierd Question

Where the heck is the Knock sensor located at on my gals 99 buick regal 3.8 V6. Any info from you wrench heads would be so valueable. THANKS

Let start out with why are you replacing it?

Its rare to see one of these go bad.

How many miles are on the car?

[Jim Uran]

I'm replacing it because I had a guy at the shop run it through his computer and he said that's what came up?? I also changed the fuel filter but he said the knock sensor is bad. It's a rebuilt motor with about 200,000 miles on it but I dont know I already have the part I just need to know where the heck it is on that particular motor.

the one on the right side is under the exhaust manifold. The one one the left is in front of the starter.

Airjer is right it is rare...I've seen 1 maybe 2 in all my years that was actually bad. Whatever the case if you want to do it.....its not always a fun job. You may have antifreeze pouring out if you dont drain the system first. On many models (not all) the knock sensors are threaded in the block into the water jacket of the engine. When you remove it antifreeze may be gushing out, so let it cool off before trying to do it. Some others (if you are lucky} are threaded into a solid part of the block and no water will be present, so you'd be wise to remove it slowly to see if any coolant starts to seep before taking it out. If it does you'd better drain it first.

[Jim Uran]

yeah I figured it'll be a crazy job I'm just wondering on that particular engine where it would be and if it would be accesible from the top. Thanks for the info fellas
