I know this question may come up a lot but is it normal for coolant level to be a bit lower before start up. I checked the radiator and it was full. I notice after running the truck for awhile during the day the level is up to the top. The picture shows what I saw before starting truck up. It’s getting warmer so the outside temp was in the mid 60s. Sometimes the reservoir is slightly lower than the one in the picture but never empty. I already had the water pump replaced months ago and also had to get a new radiator cap.
