Car randomly gets warm
So my car is being moody. Its 110 degrees here, and if I turn on the A/C on high, it will warm up a little. If I drive it hard on low/medium, it will warm up a little. If I drive at night after driving it during the day, when going 95, it will warm up a little after about 10 miles, but then it goes right back down if I put the heat on low.
Now. If I drive with the A/C on medium, and I drive around town like a sane normal person, nothing happens. If I dont drive it across town twice during the day, and then three cities over at night for work, nothing happens. If im not running the air pump for the stock suspension, none of this happens. But air pump + a/c+ driving hard and it heats up.
HG is fine, water pump is fine, thermostat is a new fail safe one. Im thinking either the fan clutch, or I need a new radiator. The radiator also leaks just SLIGHTLY at the banjo bolt on the passenger side of it.
I just want to make sure if I order a radiator tomorrow that im not just pissing away money.

Thanks Billy-
Your pic shows it but the single wire sensor location but the parts diagram doesn't show it. One of the ECT threads has a part# for the sensor I'm thinking but I don't know what it is actually called. The sensor is about $25 my memory recalls.
Your car is probably at proper temp but because the gauge sensor is going south it indicates a false reading.

other than the sensor, it would be a good idea to bleed the coolant of any air. i find that you really have to run the car for 10-15mins holding the RPMs up to get all the air out.

So replace this coolant sensor to the gauge?
I am going to replace the radiator soon and rebleed it all. If I need that sensor too, ill throw it in my cart on rockauto. Anyone have the part number off hand?

Has any work been done on the car,recently, that would require coolant to be added or removed? If so, I would strongly suggest bleeding the system. I had an overheating issue and it was either caused by a faulty thermo or fan clutch. After that, i bled the system and she was back to perfect. Or, it could be as simple as the ECT sensor. Either way, properly bleed the system if you haven't done it. I hope it all works out for you!

Yeah I have replaced the coolant resevoir after the sensor thing was leaking... but since the radiator leaks from that banjo bolt, could I just need some washers for that bolt??? it could be air getting in from there
