Review on Sierra International 18 3611 Marine Thermostat by Jeff Bennett

Using this product our team found that it was not compatible with our automotive engine .The installation process was difficult and time-consuming, and once we finally got it in place, it failed to regulate the temperature properly. We ended up having to replace the thermostat mid-trip, which was frustrating and costly. The only positive aspect was the affordable price. Overall, we do not recommend this product for anyone looking for reliable marine engine cooling..
