So my question is, are both these sensors the same as in what they do? Here is my problem... the coolant temp sensor and the small clip that slides over the top of the sensor, clears the headers nicely. Now for the fan switch, which is in the same place but on the other side of the motor had a top that requires a big plastic plug that snaps on top, This makes for a very tight fit with the headers and I am worried about melting it down. Here are some pics to clarify what I am talking about. I was wondering if I could use the coolant sensor and change the plug as such to keep it away from the header??? thoughts??

 

Different animals.

 

K. Thanks!! I'll figure out something for heat protecting

 

FWIW, the installation kit that came with my SLP tri-y headers included a 90-degree elbow for the fan switch. It points the sensor down towards the starter.

 

The coolant gauge sensor is a sensor and delivers values within a certain range for the gauge to react to.
The other one is a pressure switch, not a sensor, and simply closes without sending values of any kind.
Therefore, you can not interchange them.

The stock big plastic plug tends to break down over the years anyway, due to its proximity to the header. At least mine did. The heat gets to them.

 

Oh that is a good idea!! I will look into that and see if I can get one. The end of this connector is so close! thanks so much for the info!

 

You wouldnt happen to have a part number? I googled a bit, but cant seem to find anything.

 

You should be able to get one at a hardware store...last I looked, SLP doesn't list much for 3rd gens anymore.

 

good point, i didnt even think of just a regular elbo. that will definatly do it! thanks again!!

 

Sorry. No part number is listed. It's just a hardware store item. IIRC, it's a 1/4-NPT male/female elbow.

Even with the elbow, get some fiberglass heat sleeve and put it around the connector. It still gets hot around there. Route the connector between the battery cable and the block.

Most "real" auto parts stores will have a replacement connector hanging on the wall if you need one.

This one was hurt but still in action when I replaced it.


SLP still owes me the spark plug socket. I bought the headers in April 1989.

 

heat sock is a good call!!! ill deff do that as it is in like new condition at the moment.
