Radiator hoses

I finally got my Roto-Fab intake installed on my 2013 Caprice yesterday. With all the factory stuff out of the way I have a good view of the radiator hoses. When the car is cold and not running both hoses are collapsed. The car does not run hot and when it hot or running the hoses are normal. Has anyone else seen this? My guess is I need new hoses. The car now has 75,000 miles. The hoses look original.

I would try a new radiator cap. That ain't right.

I have this same problem. If I unscrew the radiator cap they stay collapsed. All hoses appear in good shape have new ones in the garage.

If they collaps for long enough they start to remember that as the default position. The new radiator cap will sort of retrain them by venting / suctioning correctly at the right times. If it still does it after a month or so may have to replace the hoses.

Then I will order a new cap and replace the hoses. May take a while but will try to update. I am still new at sourcing parts.

I had the same issue. A new radiator cap fixed the issue as mentioned.
