My '90 Legend is building up tremendous pressure in the cooling system after , say 150-200 miles of driving (not all at once). It is also using coolant. The oil is squeaky clean as is the coolant itself so I don't think there is a head gasket issue. However, EVERY time I take a very sharp left-hand turn, I'll get an obnoxious wisp of smoke from under the hood (pass side) and a burning smell. This could be the coolant, I guess, but why under those circumstances only? BTW, the engine does not burn oil between changes so its not oil. Engine is a V6 w/5 speed and about 103k miles, all original. Just a thought-what are the symptoms of a failing water pump on an Acura? I have to add coolant and purge the air from this car every 3-5 days or I'll get no heat from the vents. It also spikes all the way to HOT when I start out in the morning but comes back down to normal after the car is revved slightly. I'm stumped!
