I have a overheating problem that I need help with. We have changed
the thermostat and bleed the system but it still overheats any ideals?

Is it actually overheating or is the temp gauge inaccurate?

If it is overheating, check the fan clutch, make sure that the thermostat
was not installed upside down, and make sure that you use a 50/50 mix of
coolant and water.

If all those check out, then check for head gasket leaks and proper ignition
timing.

You probably need to replace the Radiator ...they have a habit of scaling up
inside.
