Got an 1987 300E with 172k miles on it. I just wanted to know at what point the auxiliary fan comes on in this particular car - i read on a somewhat related thread that for a 190E it kicks in around 110C, is it the same for the 300E? Around here, the summertime temps get up in the 100-110's (F, not C), and my engine temp routinely gets up to about 110C sitting at idle in traffic - awfully close to that 120 redline. Is this basically normal for this car under these conditions, or is my cooling system not working as it should?

thanks,

anthony
