I have a 93 z28 camaro and i was going to flush the coolent. I read shoebox website and everything seems to be great but i have a 93 and there is no knock sensor? So what is on the other side if there is no knock modual?

 

On a 93, the knock sensor should be located on the passenger side of the block. The right side will have a screw in plug.

 

i didnt think that 93 have knock moduales?

 

93's do have knock sensors but they don't run a traditional knock module like the 94-97s do.

 

Yes, '93s do have a knock sensor behind the starter.

 

A 1993 computer does not have a replaceable knock module.
You are confusing two different things. The module is in the computer and the sensor is on the block (same place on all 4th gens).

 

Shoebox - I sure do appreciate your website. It's a coincidence that I was looking for info. on properly flushing my radiator today. Thanks man!!

 

Have fun unscrewing (and re-screwing) that plug on the driver's side. I finally took a torch and bent a wrench into a shape that would work. Like to never got it back in. It is one of those places like the #8 sparkplug that you can touch and not much else.
