Took my car in today to get a code check ( i already new what it was). p2181 they said i have to replace the thermostat (which they didnt have on hand) so i have an appointment made. My q is does anyone know how much this will run me? I know that its alil more harder than a reg thermostat cuz of the location but they were making it like its some big job to do. Actually think he said thats a big 4 r job. Just like to know how bad its gonna be
