AC all time on!

AC all time on!
Now that the outside temperature where I live is around the 95s, I have to have all the time the AC on. I have noticed that the coolant temp goes all the way to the excatly the mid (210F?), and when I turn it off it goes down to where it always is, 1/4 of the scale (around 185F?)
Is it normal for all of you using your AC?

Depends on lots of things. AC transfers heat to radiator, and in the radiator was under specified or is getting old, not taken care of, yes the A/C will increase the coolant temps. Your figures are not out of place. Most likely your radiator could be cleaned but 210 F is not an unusual value at all.

It's pretty straightforward. Radiators need to radiate. Air flows through the radiator to cool the fluid which cools your engine. Things that block the radiator will make it cool less. Leaves, bugs, debris etc. A pressure washer usually does the trick. Does it need brushing? It's awfully tight in there and you'd probably have to take apart the grill for that. I've never seen a greasy radiator, but if it is then you need fix some bad oil leaks LOL

After 18 years the radiator may be losing the ability to effectively transfer heat. Bugs, debris in the fins certainly don't help. I would inspect the radiator for debris build up and missing fins. I would suspect scaling in the interior passages of the radiator. Kinda like cholesterol build up in your arteries. The radiator can be rerodded, but it's probably best to just replace it. Has the coolant been replaced on a regular basis? Over time the additives in the coolant lose the ability to protect the system from corrosion.
