Is it running hot? If so, try thermostats, radiator caps, and might as well replace those hoses, they look to be a little old. Might as well take the reservoir off and clean it good. Re use Coolant, since it’s new. If not, at least clean the reservoir and replace caps, for now. Hoses look old. Caps are cheap. Don’t know how much pressure your getting in system. If it’s a lot, you might want to check for bad Air compressor, cracked head gasket/ cracked head. I doubt the radiators bad, only 3 yrs old.
Coolent System Questionable
