[rally]

Thanks for the info guys. I had a chance to test it today. The needle sits lame under C and doesn't move at all at operating temp. I pulled the wire from the sender today and grounded it on the alternator and it pegged out. So the gauge seems to be good. There's definitely some corrosion on the connector, though, so I'll clean it up and see if maybe it just wasn't connecting properly.

But in the meantime I'm also looking around for another sending unit in case it really is bad, but I'm noticing a few different product numbers that say they'll fit a 350: TS76, TS 11, etc. Anybody know which sending unit is the right one? I haven't pulled mine to see which one I'm currently running because I wasn't sure if it's going to dump coolant or anything when I pull the unit. My drain pans are full and waiting for an oil pickup.

Thanks again for the help, everyone.
