I'm Awesome
Just out of curiosity did you get the ACDelco part number I posted up? I've had issues with Stants and other aftermarket brands in the past but that factory ACDelco thermostat has never given me issues.
Either way, glad it improved at least a little.
That Delco 131-151 is the thermostat I have in my truck (1998, 350). Have never had any issues with it.
The gauge in my truck with that thermostat has never been accurate but the one in my Tahoe is. That's the one that I posted a gauge picture of a couple days ago.
Truck's gauge reads 155 with the upper radiator hose hot. The ECT sensor reports 192 which agrees pretty closely with Delco's thermostat literature claiming a 197 (?) setpoint.
