Leaking coolant


If the water pump was bad, it would either leak water out the front of engine from the pump (bad seal inside the pump), or it would not circulate the coolant through the engine and the radiator (bad or worn pump impeller blades) but then for sure, the car would overheat.
Where was the smoke coming from, the exhaust or the engine area? If it's from the engine area, the coolant was probably leaking on the engine and then boiled away. If you had white smoke from the exhaust, coolant is entering a cylinder from a head gasket leak and being burnt off inside the engine.

Over heating


Common causes for over heating are listed below:
  1. Lack of coolant
  2. Leaking radiator (usually on a seam)
  3. Leaking coolant line (usually but not always around the fitting)
  4. Bad thermostat - prevents sufficient coolant from entering the system from the reservoir
  5. Bad waterpump (will usually leak but not always, can be bad waterpump bearing)

2006 Pacifica 3.5L I have a small coolant leak on the passenger side. The coolant will trickle down and drip from oil pan. The puddle is only 2 inches wide. I did a pressure test at 17PSI and I lost 2PSI...


It is a possibility that the leak may come from bad seals from the water pump or a bad water pump. If you also observe bubble in the coolant inside the radiator when the car is running or water coming out of the exhaust you may have a bad head gasket. The coolant comes out of the bad part of the head gasket near the outside which lets water outside the engine as well.

IF CAR OVERHEATING WHILE IDLING YOUR COOLING FANS NOT WORKING CHECK COOLING FANS FUSE AND RELAYS.IF FUSE AND RELAYS OKAY THE ENGINECOOLANT TEMPERATURE SENSOR BAD.

SMOKE UNDER HOOD COULD BE COOLANT LEAK FROM RADIATOR ITSELF OR CHECK FOR LEAKING TOP RADIATOR HOSE AND CHECK FOR LEAKING BOTTOM RADIATOR HOSE.LOOK UNDER THE HOOD IF COOLANT BOILING OUT COOLANT OVERFLOW JUG ENGINE OVERHEATING FROM BAD THERMOSTAT OR BAD WATER PUMP.CHECK FOR COOLANT LEAK AT WATER PUMP WEEP HOLE.IF SO WATER PUMP NEED REPLACING.ADD MORE COOLANT UNTIL LEVEL CORRECT.TRY LOCATE LEAK. IF CAR OVERHEATED AND BOILED IT OUT. SMOKE UNDER THE HOOD CAN ALSO BE CAUSED BY LEAKING VALVE COVERS WHICH CAN BE FIRE HAZARD IF OIL LEAKS ON HOT EXHAUST MANIFOLD.

I have coolant leaking out of the fan pulley. why?


If the coolant is coming out of the one that's more to the center of the engine, it's going to be your water pump, when water pumps go bad they will leak coolant out, water pumps have a little hole in back of the pulley, that when the seal goes bad it will leak coolant through there.

My heat quit working&now im having to had water to everyday


Heat not working is either a sign of a bad thermostat or bad water pump. Since you have to add coolant I would also imagine you have a major leak. Try to verify where the leak is coming from. Heater cores can also fail but you would have coolant in your car on the passenger side floor and you would notice the smell of antifreeze. Do not drive your car until you fix this. This will destroy the engine in no time!
