Tpi temp sender.

Can anyone tell me where the temp sender is located on a 91 350?

Thanks

The TPI coolant temp sensor is located at the front of the intake manifold. The intake air temp sensor is threaded into the bottom of the plenum, near the back.

The is also the coolant temp sender for the gauge which is on the block driver's side under exhaust, between 1&3 cylinders if I remember right. Should have a green wire going to it.

Re: Tpi temp sender.

The temp SENSOR is on the front of the intake manifold, the temp SENDER is between the first and third cylinder on the drivers side head. Should have a green wire going to it that slides right onto the senders connector.

When I replaced mine I was kind of intimidated since its in a spot where you can't really see and I was worried I might snap the head off or the threads would be stuck but in reality it was a very easy replacement and came right out, I lost minimal coolant too. just have the new sender out and ready to screw in once the old one comes out. Good luck
