2018 Chevy Silverado thermostat
Worked great, my 2018 Silverado took forever to heat up. I replaced my old one with this one and it works great, shipping was right on time

Great quality and perfect fit, resolved my cooling fan problem
Perfect fit, quality and easy installation. My cooling fans were running all the time. I replaced the temperature sensor and it didn't fix it, but once I replaced the thermostat, the problem went away and it warms up quicker. the OEM model from AC Delco was on backorder so I purchased this which had the best reviews and pricing. Will buy again.

Needed one for my 2018 silverado and didn't want to pay 300 bucks for one so I tried this and had it in my truck for over 8 months now and it's worth buying

I figured i needed a new thermostat because my truck warmed up so slowly. Turns out the rubber O-ring had pulled out on the factory thermostat and it wasn't sealing anymore. This did the trick. Warms up WAY faster and runs at 207°F.

OEM fit/finish/operation for half the price, it’s a no brainer!
