Hey folks, I need a few opinions. A few days ago there was this "scavenger hunt" all around town, which requires very aggressive driving. My car has never overheated until this day. When I pulled to a stop and got out of my car, I noticed coolant leaking on the ground. I popped the hood and took a look around, and eventually pulled the radiator out, and all is well. My theory is that the engine got so hot the coolant expanded and came out the overflow container. Since then I have filled the thing back up with coolant, put the radiator back in, however it still overheats. Just driving around town it will heat up to normal operating temperature, and it will stay there for a while, then it will gradually start to creep up the temp scale. With the engine running, I popped the hood to verify there weren't any leaks, and noticed one of the fans on the radiator went out. The driver's side fan, however, was working perfectly. I can't quite remember, but I think that this fan didn't work before, but I can't be certain.

My question to you is, is this one fan out of comission able to cause this gradual overheating? If that is unlikely, do you think it could be the water pump? Any opinions appreciated!

Oh yeah, the A/C has not been on at all during this.

The most common part that fails when car is overheating is Thermostat, some how it get stuck in one position. I you decide to get the part, get it from a Nissan dealer.

The other part I can think of is Coolant Temperature Sensor. How it affect? I don't know. Maybe it's not turning on your fans.

Check the engine oil, make sure coolant hasn't gotten in. Could be damage to the engine block if coolant and oil mixes.

Other people on the form might have better answer.
