Thanks for the feedback, I will be replacing the items mentioned.

I have a question for the group. I'm in the process of changing out the radiator on my 2019 Sierra 6.2 AT4, it cracked in the same place I've seen from other members in this forum. Being that I'll have access to the whole front of the motor, is there any components I should change out as preventive maintenance, I have 105K miles. Just thought I'd ask the group, up till the radiator issue I've had no issues.
