I have an 94 4.3 and SNB802 fitted mine no problems. It has the pre-serpentine engine which I should imagine is like yours.

The sensor you are looking for is the one by the distributor cap. I found taking the cap off gave good access to it.

Sounds like you have the wrong part. :-(

Hope that helps

These are popular!

Maybe the pre-Serpentine is different, but on mine, the sensor near the distributor and pointing forward is for the temp gauge, not the ECU, and it isn't an SNB802.

On the Serp' the SNB802 is on top of the manifold, nearby, and points upwards, beside the other temp sensor that is not connected.

I may be wrong, but just wondering if you have removed the wrong sensor.

There are two different size threads available. I think one is metric and ond imperial.. I took the larger one back to the motor factors and he swapped it for the smaller one...
