I did a motor swap and I am looking where to connect my water temp. sensor. I see 3, one on the water pump, one on the pass. side and the other on the driver side.
Thanks Chris

What motor is it? If it's a standard SBC, then it should be on the passanger side. But, as long as it's in coolant, it should be okay. I would avoid the water pump though...

*edit*

Wait, are you saying that there are 3 places to put the temp sensor, or 3 DIFFERENT temp sensors?.....

rodj

You don't say which temp sensor?
There are two different ones
CTS for ECM goes in water pump on a LT1
factory sender for temp gauge goes in pass head to fit stock harness

Its a 94 corvette LT1. I was told there were 3 sensors.

I'm new to the LT1, what do you mean which sensor. I'm putting an after market gauge,cyberdyne, and do not have a "wire" to connect the gauge.
I know I have to get a sender for the gauge but dont know where it goes.

rodj told you the correct answer. For a little more detail the sensor on the water pump sends the info to the PCM, which in turn also feeds the digital gauge. Then there is a sensor on the passenger side head between #6 and #8 cylinders that simply feeds the analog gauge. The F body LT engines have the same sensor on the driver's side head between #1 and #3 cyllinders. For a stock Corvette LT engine the one on the driver's side is plugged off with a 3/8" pipe plug. Hope this helps clarify it for you.

that's perfect, this is what I needed to know. THANK YOU

Would have easier if you mentioned that essential fact up front
