A ruptured head gasket can let coolant leak into the cylinders, causing the engine to consume coolant. To check for a blown head gasket, first look at the exhaust pipe with the engine hot and the car running. Is there excess steam or water dripping from the exhaust, are you sure it is not condensation. if the coolant level keeps going down in coolant recovery tank. it could possibly be a bad head gasket or cracked head. Good-Day!

SOURCE: 1995 4Runner: coolant coming from exhaust pipe?...

Coolant coming from the exhaust pipe is a common indication that you have a blown head gasket. This is a fairly common problem on 4runners equipped with a 3.0L V6 engine. I do not recommend driving the vehicle in this condition even if it is not yet overheating because it can lead to serious engine damage.

Dumping gas into oil and blowing white smoke changed the fuel pressure regulator no difference


White smoke is coolant getting into the cylinders , blown head gasket cracked head or crack in the block etc... . If the engine were running rich ,then black smoke would be coming out the tail pipe -exhaust !

Water coming from exhaust of my 1994 isuzu trooper why


Water out of an exhaust pipe is usually just hot gasses condensing on the surfaces of cooler metal exhaust pipes, and is normal. White steam or "smoke" however is in indication of coolant entering the combustion chamber and boiling off during ignition. It is superheated water vapor (more than 212 degrees) and turns to visible steam as it cools when leaving the exhaust pipe. This is the result of a cracked engine block or gasket and can be an expensive fix. Check and monitor your coolant level if unsure of the cause. Also check for milky colored oil on the dipstick - this is a sign of coolant entering the crankcase - also not good!

My husband and I are trying to get to our thermostat to change in my 2002 rendezvous, but there is a metal pipe in the way that we can't figure out how to remove. just behind the pipe, is a metal plate...


Hello vocalviixen,

The pipe that you referred to is the exhaust crossover pipe. Below I've included removal and installation instructions.

Also, the procedure for bleeding the coolant system is critical; if you need those instructions please post the question.

REMOVAL PROCEDURE
1. Disconnect the battery ground (negative) cable.
2. Remove the throttle body air inlet duct.
3. Drain the coolant from the cooling system.
4. Remove the inlet radiator hose from the engine.
5. Remove the thermostat bypass pipe.
6. Remove the exhaust crossover heat shield bolts.
7. Remove the exhaust crossover heat shield.
8. Remove the exhaust crossover pipe studs/nuts.
9. Remove the exhaust crossover pipe.
INSTALLATION PROCEDURE
1. Install the exhaust crossover pipe.
2. Install the exhaust crossover pipe studs/nuts.
3. Tighten the exhaust crossover pipe studs/nuts to 18 lb ft.
4. Install the exhaust crossover heat shield.
5. Install the exhaust crossover heat shield bolts.
6. Tighten the exhaust crossover heat shield bolts to 89 lb in.
7. Install the thermostat bypass pipe.
8. Install the inlet radiator hose to the engine.
9. Fill the cooling system with engine coolant.
10. Install the throttle body air inlet duct.
11. Connect the battery ground (negative) cable.

How do I replace a water pump on a 1999 malibou with a quad 4?


Water Pump REMOVAL & INSTALLATION CAUTION
Never open, service or drain the radiator or cooling system when hot; serious burns can occur from the steam and hot coolant. Also, when draining engine coolant, keep in mind that cats and dogs are attracted to ethylene glycol antifreeze and could drink any that is left in an uncovered container or in puddles on the ground. This will prove fatal in sufficient quantities. Always drain coolant into a sealable container. Coolant should be reused unless it is contaminated or is several years old. 2.4L Engine
  1. Disconnect the negative battery cable
  2. Detach the Oxygen (O2) sensor electrical connector.
  3. Properly drain the engine coolant into a suitable container. Remove the heater hose from the thermostat housing for a more complete coolant drain.
  4. Remove upper exhaust manifold heat shield.
  5. Remove the bolt that attaches the exhaust manifold brace to the manifold.
  6. Remove the lower exhaust manifold heat shield.
  7. Break the manifold-to-exhaust pipe spring loaded bolts loose using a 13mm box wrench.
  8. Raise and safely support the vehicle. NOTE: It is necessary to relieve the spring pressure from 1 bolt prior to removing the second bolt. If the spring pressure is not relieved, it will cause the exhaust pipe to twist and bind up the bolt as it is removed.
  9. Unfasten the two radiator outlet pipe-to-water pump cover bolts.
  10. Remove the manifold to exhaust pipe bolts from the exhaust pipe flange as follows:
    1. Unscrew either bolt clockwise 4 turns.
    2. Remove the other bolt.
    3. Remove the first bolt. NOTE: DO NOT rotate the flex coupling more than 4°or damage may occur.
  11. Pull down and back on the exhaust pipe to disengage it from the exhaust manifold bolts.
  12. Remove the radiator outlet pipe from the oil pan and transaxle. Leave the lower radiator hose attached and pull down on the outlet pipe to remove it from the water pump. Leave the radiator outlet pipe hang.
  13. Carefully lower the vehicle.
  14. Unfasten the exhaust manifold-to-cylinder head retaining nuts, then remove the exhaust manifold, seals and gaskets.
  15. Remove the front timing chain cover and the chain tensioner. For details, please refer to the procedure located later in this section.
  16. Unfasten the water pump-to-cylinder block bolts. Remove the water pump-to-timing chain housing nuts. Remove the water pump and cover mounting bolts and nuts. Remove the water pump and cover as an assembly, then separate the two pieces. Fig. 1: Water pump and cover mounting - 2.4L engine 87953070.gif
    To install:
  17. Thoroughly clean and dry all mounting surfaces, bolts and bolt holes. Using a new gasket, install the water pump to the cover and tighten the bolts finger-tight.
  18. Lubricate the splines of the water pump with clean grease and install the assembly to the engine using new gaskets. Install the mounting bolts and nuts finger-tight.
  19. Lubricate the radiator outlet pipe O-ring with antifreeze and slide the pipe onto the water pump cover. Install the bolts finger-tight.
  20. With all gaps closed, tighten the bolts, in the following sequence, to the proper values:
    1. Pump assembly-to-chain housing nuts:19 ft. lbs. (26 Nm).
    2. Pump cover-to-pump assembly: 106 inch lbs. (12 Nm).
    3. Cover-to-block, bottom bolt first: 19 ft. lbs. (26 Nm).
    4. Radiator outlet pipe assembly-to-pump cover: 125 inch lbs. (14 Nm).
  21. Using new gaskets, install the exhaust manifold. Make sure to following the tightening sequence and torque specifications given in the exhaust manifold procedure located in this section.
  22. Raise and safely support the vehicle.
  23. Index the exhaust manifold bolts into the exhaust pipe flange.
  24. Connect the exhaust pipe to the manifold. Install the exhaust pipe flange bolts evenly and gradually to avoid binding. Turn the bolts in until fully seated.
  25. Connect the radiator outlet pipe to the transaxle and oil pan.
  26. Install the timing chain tensioner and front cover.
  27. Install the lower heat shield.
  28. Carefully lower the vehicle.
  29. Fasten the bolt that attaches the exhaust manifold brace to the manifold.
  30. Tighten the manifold-to-exhaust pipe nuts to specification.
  31. Install the upper heat shield.
  32. Attach the oxygen sensor connector.
  33. Fill the radiator with coolant until it comes out the heater hose outlet at the thermostat housing. Then connect the heater hose. Leave the radiator cap off.
  34. Connect the negative battery cable, then start the engine. Run the vehicle until the thermostat opens, fill the radiator and recovery tank to their proper levels, then turn the engine OFF.
  35. Once the vehicle has cooled, recheck the coolant level, then install the radiator cap.

How to replace the water pump on 1993 oldsmoblie achieva.


2.4 enigine is the harder of the 3 enignes. it will need a timing chain to be removed and a coolant tube in the back of the engine to be removed. this job on the book calls for almost 7 hours.

if its 3.3 or 3100 its alot easier.

3100 is just 4 10mm pulley bolts and 5 or 6 small 8mm water pump bolts.

3.3 is alittle more work, but same concept as 3100 engine. more owkr only cause its in a tighter area.

good luck,
michael
