My 1989 Corolla has began running warm lately....not to the point of
overheating but slightly above the normal "9 o'clock"positon of the heat
indicator needle. It gets up to about the "10 o'clock" position, which
is still below the danger range. Otherwise the car runs fine. It has
102k miles on it. Any suggestions about what is causing this would be
appreciated.

I'm not an expert on this, but a slight warming of the engine could be
due to the engine running leaner than usual. A lean fuel mix will burn
hotter than usual. It may be of some help to the people in this forum
to give a more in depth description i.e is fuel economy roughly the
same, is there loss of power, has it had any recent work etc.
Lean mix could be caused by low pressure fuel, maybe a clogged fuel
filter or fuel line? Any other info you have might help out a bit

Have you ever replaced the thermostat? It could be sticking a little.
Simple and cheap fix if thats the problem. They make new ones now that
if they fail they fail in the open positiion. Get one of those. It
could save you some headaches.

Good Luck

Pete
