I changed the engine coolant out a couple weeks ago and after following the manual for flushing the old coolant, I put in Zerex Extended Life at a 50/50 mix.
After the engine comes up to temp, I can watch the temp gauge fluctuate between what was the normal operating temp and back down some. It stays in the green and never goes above what has always been the normal temp but I've never seen a temp gauge move like this. The coolant in the radiator looks just like it did when I mixed it in the jug.
