Here's the problem. I was on my way to a friends house and after driving about 99km to get there, I have noticed that my temp gauge started to go up a little above the cool mark and then it went back down. After finding a parkin spot, it raised up again but this time about 3/4 higher. It didn't officially overheat but look like it was going to. Its didn't touch the "H" but was scared it was. I drove back home and no problem wha so ever... I checked out my coolant level and all is at normal specs. I did notice the night before my car took a little than normal to actually get heat in my car. The fans come on when the A/C is on. The only time I see "white smoke" from the exhaust is when startin the car first thing in the morning and its chilly out. Its normal exhaust smoke. Not cloudy white... I got a 2001 Acura EL and did do some searches and found out info. I am taken in all knowledge from those post. Was wondering if anybody havin this issue and what should I start replacing first??? Thanks y'all
