Repairing the hated 95 Olds

Well the new sender did not change a thing. I'm still convinced it must be a bad sender. When you disconnect the sender both fans come on after a short delay, as they also do when A/C is activated. I topped off the coolant, I don't think I got 1/2 gallon, if that, into it before it was ABsolutely full Heater puts out HOT air, showing me the water pump is working.

Went to NAPA they didn't have one, either. Sposed to have one tomorrow, I'll try one more. (sender)
