Michael,

The bleed screw on the radiator is actually a bolt that is on the passenger side of the radiator.  The original has a groove in it so air and coolant can pas when it's loosened.  In a lot of cases the bleeder has been replaced with an actual bolt so it may have to be removed altogether rather than just loosening it with a 13mm wrench.

Where is the bleed screw? I took off the grill and can't see it.   I replaced my
oil cooler hoses and want to bleed the system.  I have a blinking red light on
the temp gauge about 1 mnute after start up. Idels about 1100 rpm right now, but
still cold. hanks, Michael
