Finally got around to changing my thermostat on my 460 because the old one may have been may have been sticking open.
The one I removed was a Motorcraft ET8E-8575-AA (192 degrees F), original from the looks of it. The one the local auto parts sold me to replace it is a Stant 45359 (195 degrees). The problem is that the Stant looks like a POS compared to the Motorcraft. Should I return the Stant and get a Motorcraft or similar brand or has the technology and construction methods changed.
What are your thoughts

Thanks
