Before getting so uppity and condescending, you could try reading the title, capiche?
Looking up from the puddle tells one nothing, because it runs down the side of the engine, you know gravity, and drops off from the lowest point. There is coolant on both sides of the engine, probably because of the fan.
What I'm trying to ascertain, is that if the glow plug is plugged in, and working, and coolant is leaking, is that symptomatic of anything?
