LT1 coolant temp sensor

I'm changing out my water pump on my '94 LT1. I can't get the coolant temp sensor out of the old pump. I guess after 19 years, I could use a new sensor.

Discount Inboard Marine has the sensor, but I need it tomorrow. They have one at NAPA.

Does anyone know if the automotive is the same sensor? This is the one at NAPA. Same connector.

That sensor will be fine, as will a water pump for a '92 Corvette. Have you already bought the pump?

An automotive pump will work but I believe the wp is marine specific for corrosion resistance w raw water so may not last as many years.

I rebuilt my original factory water pump with new bearings and seals. It was an aluminum body with a steel impeller just like the auto units. The impeller was rusty and pitted, but I cleaned it up and put it back in.

Thanks for the advice, guys. Yes, I bought a pump for a '92 Corvette. It's the same as the one I just took off.

Automotive, but still specific to the LT-1, right? If not, your heads will go away pretty soon. The LT-1 pump cools the heads first, then the rest of the engine.

He would have to get a pulley, new belt, etc. to run the wrong water pump since the LT-1 is shaft driven. Hopefully it would be hard to make that mistake.
