Hi drrusscampbell ,

You'll likely get better response at a Mustang board , since this board covers 82-92 Camaro and Firebird only . As a generic answer , not knowing anything about Mustangs , have you done a pressure test on the cooling system ? And if it has an automatic transmission , have you checked it's fluid ?

Good luck

Re: engine oil in radiator, NO water in oil

Fluids go from high pressure to low pressure. Cooling system maxes out around 15 psi. Oil can be up to 80. Without knowing anything about a mustang since this is a third gen site, the only thing that comes to mind is an engine oil cooler. I have no idea if a mustang uses an oil cooler or not.
