2005 SL600 - Engine Heat
? My 2005 SL600 seems to produce a lot of HEAT from the Engine. People who have walked up to the car and talked to me thru the window have made comments of the heat and after shutting the car off, as you walk by you can feel the heat. The temperature gauge is in the normal area, is this normal???

It's hot in there - the radiator coolant would boil if it wasn't under pressure and especially when idling in high ambient, the car is sitting on a thermal knife edge. My old SL600 is exactly the same, the front wings/fenders get very warm and stay that way for a while when the car's switched off. So sounds completely normal to me.

That engine does hold a huge amount of heat. After parking my 600 and starting it hours later the temperature gauge will still read 40 C or so. The thermal inertia is much more than even the AMG supercharged V8.

The huge size of the engine, the extremely hot turbos and huge radiator capacity generate huge amounts of heat. As the car is still, the hot air cannot be replaced by cool air, and you can get huge heat waves. Completely normal, and even if the engine was overheating I dont think you would notice from feeling more heat coming from the car. Nice car by the way
