I understand wanting to keep the temps down and making them last longer. Mud filled rad condenser and aux cooler will definitely raise your tempurature. I just checked my spare oem thermostat 82 degrees C 179.6 F. So Don't be too hard on yourself. We all boo boo and learn to keep the radiator area cleaner.. :-)
