First let me explain that my car is NOT running hot nor is it leaking any radiator fluid. It's operating at 180-185degrees as it should, but I found this to be a little strange.

Low radiator fluid light in the cluster came on, so I check the fluid in the resevoir and it's full. Well I've just driven the car for 2 hours so I really don't want to open the radiator cap because it's pressurized from the driving, right? Actually, NO it wasn't. I turned the radiator cap 1/2 turn expecting the pressure to bleed off into the resevoir, but there was no pressure. I was able to take the cap off immediately after driving the car for last 2 hours straight. Why is there no pressure? The cap is rated for 18 lbs. The radiator was full also. So I think I need a new radiator fluid sensor and a radiator cap, but the fact that I had no pressure seems like it would have caused an overheating issue. Hmmmm.

180 stat with fans programmed to come on at 180.

 

That is kind of weird. You should be able to have the cap checked at a radiator shop. The low level sensor goes out often on these cars for whatever reason.
