Gates, name means QUALITY
This is a quality thermostat at a very good price. Was actually cheaper here compared to my local parts store. Plus was delivered to my house.

Keep it at opperating temperature.
This is what i want i may drill a small steam hole in it,it is now on a 1961 small block chevy that turns 6500/8000 RPM it may get hot,i think this will help keep it close to 180 degrees like it should using 4 core radiator.

Item is correct and fit my vehicle perfectly. Main problem was delivery. Had given me a delivery date Feb 28-2023. Was looking at tracking on Feb18-2023 and it stated that it had been delivered on the Feb17-2023 the previous day. Nothing had arrived. Contacted Amazon on Feb20-2023 about no part and then on Feb21-2023 there it was. Contacted Amazon again to let them know it had arrived. Amazon was excellent and the shipped company ((not so excellent)). Why they stated it was delivered when it was about 4 days later is very misleading.
