Temp fine at highway speeds .. heats up at idle

Check your fan clutch- is it engaging when idling and at op temp if not then chances are the clutch is bad.
Replace your thermostat it's usually a cheap and easy fix
it just sounds like you have enough air going through into the engine compartment to cool it down but when you have no air going through at idle it heats up which leads me to believe it's something to do with the clutch fan or thermostat.
How much more does it heat up at idle as opposed to driving on the highway? check your thermostat ratings if possible i believe my firebird's thermostat is rated for 195 degrees. If the engine temp is exceeding the temp your thermostat is rated for then something else is going on.
Always look for the small things first and replace them if you need to before replacing anything big like the water pump which isn't too hard but is time consuming. Hope this helps. Good luck.

Temperature gauge goes well past halfway when outside temp is above 80 degrees, and A/C on.

I would start with checking the fan clutch if thats fine do a completed cooling system flush and replace the thermostat if you are still having problems replace the water pump

I have an ex police crown vic 1997 it appears to be overheating if i leave the ac running for about 20 mins. i changed the fan clutch/ radiator, where should thedial actually be?

it's funny to be reading about a similar situation i'm having. i also have a '97 crown vic, bought at a municipal auction.
of course, running the a/c should put more load on the engine and produce more heat. but not enough to be concerned about. if you car seems to be overheating, the thermostat could be to blame.
while diagnosing a different matter, i noticed the coolant temperature at one point reached 217 F. i'm going to replace the thermostat as it may only be opening partialy. my temp gage is normally just above the half way point between the high and low marks. it hasn't gone any further towards the high temp mark to be alarming.
where is the needle pointing on your gage? have you replaced the thermostat?

Have changed thermostat and head gasket has bbe

I recommend replacing the thermostat and before installing it, drill a small hole in the center of the flat seating surface to bypass coolant during warm up. This will help to gradually warm the engine and it can save you some damage to the engine if the thermostat sticks. Mine did the same thing which sounds like the thermostat is sticking closed. My temperature needle goes from 1/2 to 3/4 max which is ok. Turn on your a/c and it should engage the electric cooling fan which will also save your engine from overheating. You may have a defective fan clutch.

High mileage 1996 Ford Explorer v8 overheats at 75-80 mph

if your mechanic seen no leaks from hoses or thermostat housing its sounds that either your fan clutch or your thermostat is bad. if its heats will driving streets and not highway its your fan clutch and needs to be replaced. if it overheats in streets and highway its your thermostat and needs to be replaced,you will need a thermostat and gasket with some silicone. Drain, follow the radiator hose to the housing and take 3 bolt off, clean housing well,CAREFULLY install the t-stat exactly the way is was taken out (pic), gasket,sillicone, bolt. ecc3d0c.jpg   its an easy job. Good luck!
