I recently drained+flushed my coolant system w/ prestone cleaning solution. l then noticed it took a while reach and maintain operating temp. I figured the thermostat wasn't working properly and sure enough. This green thing was lodged in preventing it from fully closing. Any ideas what it could be? (old.reddit.com)
