What is the sensor located on the passenger of the block? Is is right under the manifold. When i took it out, antifreeze came out. i am putting headers on and when i took the manifold off i broke the sensor.
thanks.

 

Is it down in the block just above the oil pan rail? If so it sounds like you broke the knock sensor. It screws into one of the coolant drains for the block.

 

It was just under the manifold in the center.

 

that's your fan switch

 

Was it this? If so that is your fan switch. i busted mine when I put my headers on.

 

yup thats the fan switch, I think everybody breaks it off when doin the headers I did. Try to get a lower fan turn on temp like 170 for little better cooling. You may also need the little clip that goes onto the fan switch mine was very brittle so I replaced it as well. And dont forget to drain the coolent from the block, I got sidetracked forgot to drain it a bit and lets just say the drive was needing a good hose down

 

On a plus side my fans stay on all the time now. As soon as the car starts they come on and stay on. Are the Jet fan switch's worth it?

 

YES!! Thats it. Thanks a lot. Ive got my fan hooked up to a switch. Wonder if i should replace it? But anyways, thanks again.
