[QUOTE="Ferendon, post: 3441026, member: 578259"] It's coolant... What is coolant's purpose? To cool the engine. If a normal combustion chamber, gets to 1600*, then how hot would a cylinder get, with a wet spark plug, and coolant on the piston, and cylinder wall? A wet spark plug doesn't spark, at least not very well. No fire = no heat = much lower combustion chamber temp. Each spark would burn off a tiny, and I mean TINY bit of coolant. By the time you burned off any significant amount of coolant, you would have typically caused some engine damage. The sweet smelling steam is a result of the silicates from the coolant breaking down, over time, and mixing with water. Kinda like when you boil something, after a while, you can smell w/e is in the water. Water in the combustion chamber is turned to steam, and carries the silicates with it, which creates the smell. My dad was a mechanic for 32 years, so while I'm no expert, I don't just talk out of my *** either. I changed my first set of brake pads when I was 4, and I did it without removing the caliper from the mounting bracket, and I've been up to my elbows in grease ever since. [/QUOTE]
