green sludge in radiator

Asked by Aug 29, 2014 at 11:07 PM about the 1999 Jeep Grand Cherokee Limited 4WD

Question type: Maintenance & Repair

my mechanic replaced a radiator and used blue devil to fix a head gasket leak - also
replaced thermostat and upper radiator hose - after test drive car overheated and now
there is a green sludge in radiator - I know he flushed the system at some point butnot
sure at which stage - the overheat squeal noise seems to be coming from inside the cab
of the vehicle not the exterior - not sure what to do next...
