Review on 🔧 ACDelco GM Original Equipment 25199828 Coolant Thermostat Water Outlet Assembly: Top-Quality with Seal by Kyle Herrera

This is an OEM part. I solved the problem with the thermostat after using the aftermarket which I have to return as the check engine light with the code thermostat came back on immediately after 10 days of use. A bit pricey but I went this route to avoid this car's overheating problem which is a common problem on this model due to thermostat failures as I've read all over the internet.
