2002 bonneville coolant leak


check water pump hose and the pump. a clogged thermostat can cause pressure build up and bust hoses. and of course take radiator out and check for lower hoses and crackes. if no luck, put water in radiator and run car and check for leaks. small cracks in aluminum are hard to see but expands when radiator gets hot.

Possibility of a cracked block. how can i be sure/


Vehicles: Any with the above symptoms

A cracked cylinder block will cause either:
(a) motor oil contamination of engine coolant
(b) coolant contamination of motor oil
(c) white exhaust smoke, due to coolant seeping into one or more cylinders.
(d) more than one of the above
(e) all of the above

Oil infiltrating into coolant is easy to see - drain some coolant out through the pepcock at the bottom of the radiator, and place it into a styrofoam coffee cup. Oil droplets floating on top of the green (or orange) coolant are easily seen. Or visualize oil by looking into the top of the radiator through the radiator cap.
Coolant infiltrating into and mixing with motor oil will permanently damage the engine (seizing it up through loss of lubrication), and must be prevented.
A leak from above the front suspension is, as physicians like to put it, "nonspecific", with the most likely cause a water pump seal or hose/hose connection.
A leak from near the fire wall will usually be a heater core hose, or hose connection.
A coolant leak on the same side of the engine as the water pump is a leaking water pump or water pump seal until proven otherwise.

To rule out everythng else, here's the 1999 Honda CR-V Troubleshooting Guide for Coolant Loss/Coolant Leaking:

Priority Action Part Type Cause
1 Inspect Water Pump - Worn, Cracked or Leaking Water Pump, or Water Pump gasket.
2 Inspect Head Gasket - Leaking Head Gasket.
3 Inspect Radiator - Leaking Radiator Hose(s).
4 Inspect Radiator Cap - Worn or Damaged Radiator Cap.
5 Inspect Radiator Hose - Ruptured, Cracked or Leaking Radiator Hose.
6 Inspect Freeze Plug - Leaking Freeze Plug(s).
7 Inspect Intake Manifold Gasket - Leaking, Worn, or Damaged Intake Manifold Gasket.
8 Inspect Water Outlet - Cracked, Leaking or Damaged Water Outlet.
9 Inspect Heater Control Valve - Leaking or Faulty Heater Control Valve.
10 Inspect Radiator Drain Pepcock - Loose, Damaged, or Faulty Radiator Drain Pepcock, or Pepcock O-ring.
11 Inspect Engine (DOMESTIC ONLY) - Cracked Cylinder Block Leaking Coolant into at least one Cylinder, causing white exhaust smoke.

Water pump removal


REMOVAL & INSTALLATION
2.0L Engine
  1. Disconnect the negative battery cable.
CAUTION Never open, service or drain the radiator or cooling system when hot; serious burns can occur from the steam and hot coolant.
  1. Drain the engine cooling system.
  2. Raise and safely support the vehicle.
  3. Remove the lower radiator hose from the water pump.
If the lower radiator hose is hard to reach on the back of the water pump, remove the hose at the radiator and after the water pump is ready to be removed, pull the water pump away from the engine block until there is enough room to remove the hose from the pump.
  1. Lower the vehicle.
  2. Remove the accessory drive belt.
  3. Remove the timing belt covers and the timing belt as outlined in this Section.
  4. Remove the four water pump retaining bolts.
  5. Remove the water pump.
To install:
  1. Thoroughly clean all sealing surfaces.
  2. Install a new water pump gasket and the water pump onto the cylinder block.
  3. Tighten the retaining bolts to 12-15 ft. lbs. (16-20 Nm).
  4. Reinstall the timing belt and the timing belt covers as outlined in this Section.
  5. Reinstall the accessory drive belt.
  6. Raise and safely support the vehicle.
  7. Reinstall the lower radiator hose.
  8. Lower the vehicle.
  9. Fill the engine cooling system.
  10. Reconnect the negative battery cable.
  11. Start the engine and top off the coolant as necessary. Check for leaks.


2.5L Engine

Before continuing with this procedure, be sure three new water pump retaining bolts (W701544) are available. Due to their torque-to-yield design, the bolts stretch and cannot be reused.
  1. Disconnect the negative battery cable.
CAUTION Never open, service or drain the radiator or cooling system when hot; serious burns can occur from the steam and hot coolant.
  1. Drain the engine cooling system.
  2. Remove the water pump pulley shield.
  3. Remove the water pump drive belt.
  4. Remove the water pump inlet and outlet hoses from the water pump.
  5. Remove the three water pump to left cylinder head retaining bolts.
  6. Remove the water pump and water pump housing from the vehicle.
  7. Remove the water pump to water pump housing retaining bolts and separate the water pump from the water pump housing.
To install:
  1. Thoroughly clean all sealing surfaces.
  2. Install the water pump to the water pump housing using a new gasket and install the retaining bolts. Tighten the retaining bolts to 16-18 ft. lbs. (22-25 Nm).
  3. Position the water pump and water pump housing and install three new torque-to-yield retaining bolts into the left cylinder head.
  4. Tighten the new retaining bolts to 11-13 ft. lbs. (15-18 Nm), then rotate the retaining bolts 85-95 degrees.
  5. Reinstall the water pump inlet and outlet hoses to the water pump.
  6. Reinstall the water pump drive belt.
  7. Reinstall the water pump shield.
  8. Fill the engine cooling system.
  9. Reconnect the negative battery cable.
  10. Start the engine and top off the coolant as necessary. Check for leaks.

Coolant leak - 1981 Ford F-150 straight 6cyl., no AC


from what you describe I am sure it is the water pump that is leaking, check the pump bearing for play to confirm

Have to replace water pump on 98 Ford Taurus. Any hints or suggestions would be appreciated before I get out in the snow and cold to fix this.


You can change the water pump by doing these steps:

  • With the engine off and cold, o pen the hood and locate the vehicle’s radiator and water pump.
  • Remove the radiator cap.
  • Install a pressure tester on the radiator. Apply the pressure indicated on the radiator cap or in the owner’s manual.
  • Inspect the water pump for leaks. Remove the pressure tester.
  • Place a drain pan under the radiator. Open the drain valve or remove the lower radiator hose to drain the cooling system.
  • Remove the drive belts or serpentine belt.
  • Remove any hoses connected to the water pump.
  • Unbolt the water pump from the engine. Remove the water pump.
  • Using a gasket scraper, clean the mounting surface on the engine block.
  • Install a new gasket and attach the new water pump to the engine with the original mounting bolts. Tighten the bolts to the manufacturer’s specifications.
  • Re-install any hoses and belts that were removed.
  • Re-install the drain plug or lower radiator hose.
  • Refill the radiator with a 50/50 mix of coolant and distilled water. Pressure test the cooling system and check for leaks.
  • Check and fill the overflow reservoir with coolant.
  • Leave the radiator cap off and start the engine. Idle the engine to remove trapped air from the cooling system. Add coolant if necessary.
  • Install the radiator cap.
  • Road test the vehicle and monitor the temperature gauge. If the vehicle runs hot, there may be an air pocket in the cooling system. Allow the engine to cool off and add the necessary coolant.

Small coolant leak at front of engine hose area, not always maybe 1 out of 5 times driving to work.


If you can narrow down where the leak is coming from, it will be easier for you to fix, but it is most likely either a minor radiator leak, or your water pump. You can put a can of radiator stop leak in your vehicle, such as bars leak. It wont hurt anything. If the leak continues, and appears to be coming from the engine area, the water pump is failing, but also check around the thermostat housing, near where the upper radiator hose connects to the engine

check all of your coolant hoses and clamps to make sure they are tight and you dont have any cracked hoses , if not you might have a leak in your radiator

Car began overheating, so we added antifreeze and water. Then the next day, it all leaked out. Upper hoses appear to be ok. Are there lower hoses?


It should have a lower hose also. Or you could check around the water pump, they have a weep hole on it and they usually leak if the pump is bad.
