Could it make coolant quot;Boilquot;? Ive heard myc ar's behavior is Normal, and most likely just heavy condenstaion as it DOES go away, also the behavior of the coolant and the tank.. but i DO know the Water Pump is quot;Weeping,or quot;Seeping,so i wonder what interaction that would have ont he Cooling side of the motor; what effects can it produce? What would i notice?My 1991 Calais 2.5L quot;Iron Duke,
White smoke is an indication of coolant getting into the engine. It could be a cracked head or blown head gasket. Black smoke can be worn rings or worn valves. A bad water pump could leak or make noises, the temperature is high or coolant bubbling out of the radiator.
Water pumps have a small weep hole that leaks coolant when the pump seal is bad. If the mechanic saw water leaking from that hole, that's how he knew the pump was bad. It's not a hard thing to replace, and it's cheap. They can do it in an hour for $50 - $70.
Steam coming from your headlight on a rainy night is NORMAL, since the halogen bulb makes a lot of heat. This turns the water into water vapor, (steam) as it attempts to dry out. If you don't physically hear the bearings in your water pump, or watch colored fluid drip out from under your engine, then your water pump is JUST FINE!!! STOP WORRYING! I answered one of your questions the other day. If you take my advice, your engine will run at it's best. For extra protection, drain and flush your cooling system out, and use Mercedes coolant. Dex-cool has been proved to be a potentially bad coolant. READ the dexcool litigation websites. Mercedes coolant, which is YELLOW in color, will last for 150,000 miles, and is a time tested WINNER!!! Use ONLY top tier fuels (read about this on web) and use ONLY synthetic oil, like Mobil One. CLEAN your idle air control valve and throttle plate. AND STOP WORRYING!
