Thank you for that

if your not getting sludge on rad cap

or dip stick , I suggest your issue is

the air compressor, head gasket

what I suggest is drain the tanks, remove

the big line on compressor, start and run engine

is cooling system does not build pressure

then you know thew is the problem

I hope this helped you
