my '95 GSR with 186k started running warm lately. It runs fine if its not really hot out and you are not beating on it or going up huge hills.

Normally the guage is at about 11 o'clock. Its been running up to about 1 o'clock and sometimes about 3/4's if I'm running it hard on the highway.

The AC also shuts down when it does this which is a pain.

The coolant level is normal. Any ideas?
