There is a plastic nipple that screws into the intake manifold and that usually breaks. you will need to remove the alternator to get access to the part

The hose you describe sounds like a bypass hose.
You need to replace it, they somtimes split just above clamp. Hope this helps. Good luck.

I have a leak on my 1998 ford Taurus 3.0l some where behind the belt tensioner?

Water pumps are located in that area. When the bearing goes bad it will leak and then will be hard to turn the pulley which makes the belt make a squeal sound. You should be losing water from your cooling system. Be careful, because if the engine gets overheated, you can crack the engine block. Which means mega bucks to fix.

How do i take out the wter pump offf 2001 stratus? It seems like you have to practicly take the engine out of the car to take replace it

The water pumo is located behind the timing belt cover youll have to remove the timing belt to replace it. The 2.4 engine is similar to the 2.0 Neon motor. It wasn't a quick and easy job but doable if you have a puller for the crank pulley and patience.

You will be working under the right front wheel well a lot. And like mentioned above - get a repair manual. You'll need to re-tension the timing belt.

Remove radiator and fan and anything that will block you from getting to the water pump. I suggest take pictures of each step that you disconnected all parts getting to the water pump and the removal of the water pump with a digtal camera and take the pump to the parts dealer so that you get an exact match.

Next read the instructions that come with the pump. Clean all old gasket and glue off of the place where you will install the new water pump (take your last picture you take and reverse the order and reinstall the gasket/sealer and water pump and all other parts).

Use a tork wrench on the bolts, add water and anti-freeze to the radiator and start the car and look for leaks.

Hope this helps.

How do i replace my water pump on a gmc yukon xl 2002

First you will need to remove your tension belt from all your pullies. This is usually done finding a pully that provides tension to and takes away from the belt. HINT: It will be one that doesnt have abunch of mechanical part atached behind it. After removing hte belt in the center of the motor about mid ways up there is a pully that has a hose runing behind it. The other end of the hose goes to the radiator. Well where this plugs into the motor is the waterpump. you more than likely will need to remove the pully from the pump. afd88a0.jpgAbove is a picture of your pump with the pulley removed. The four bolts in the center are how you disconnect the pulley and the four on the side of the pump are how you disconnect from the motor. Make sure when you get done and all back together to look around the new pump for leaks.

I have a water leak coming from my engine block. How to repair 2001 Buick 3.8 It is come out of a 5/8 pipe or around it

If it's a hose, best bet is to just replace it, and use new clamps.

If it's leaking where it's connected to the nipple, for a quick fix, you can remove the hose, cut the hose off past the leak, and reattach it.

This requires a little bit of slack in the hose, but if the leak is right at the connection, there should be enough slack in the hose to do this.

How to change the water pump on a ford escort 1.3gle 1986 model

  1. Let me know if you cannot see diagrams(happens sometimes) or if you have any questions
Just to make sure. I assume that you are seeing coolant leakage from around the water pump assembly.

  1. Disconnect the negative battery cable.
  2. Place fender covers on the aprons.
  3. Drain the cooling system.
  4. Remove the accessory drive belts.
  5. Remove the timing belt cover.
  6. Use a wrench on the crankshaft pulley to rotate the engine so No. 1 piston is on TDC of the compression stroke.
Turn the engine only in the direction of normal rotation. Backward rotation will cause the timing belt to slip or lose teeth.
  1. Loosen the belt tensioner attaching bolts, then secure the tensioner over as far as possible.
  2. Pull the belt from the camshaft, tensioner, and water pump sprocket. Do not remove it from, or allow it to change its position on, the crankshaft sprocket.
WARNINGDo not rotate the engine with the timing belt removed or serious engine damage could occur. The 1.3L and 1.6L engines are of the "interference type," meaning it is possible for the valves to contact the pistons if their reciprocation is not carefully timed and controlled. An engine allowed to spin freely without the timing belt could bend valves and scuff pistons almost instantly.
  1. Remove the camshaft sprocket.
  2. Remove the rear timing cover stud.
  3. Remove the heater return tube hose connection at the water pump inlet tube.
  4. Remove the water pump inlet tube fasteners and the inlet tube and gasket.
  5. Unfasten the water pump to the cylinder block bolts and remove the water pump and its gasket.

  1. Make sure the mating surfaces on the pump and the block are clean.
  2. Using a new gasket and sealer, install the water pump. Tighten the bolts to 30-40 ft. lbs. (40-55 Nm) on 1981-87 models, or to 15-22 ft. lbs. (20-30 Nm) on 1988-90 models. Make sure the pump impeller is able to turn freely.
  3. Install the water pump inlet tube and the inlet tube gasket and fasteners.
  4. Install the rear timing cover stud. Install the heater return tube hose connection at the water pump inlet tube.
  5. Install the camshaft sprocket.
  6. Install the belt from the camshaft, timing belt tensioner, and water pump sprocket.

  1. Tighten the belt tensioner attaching bolts, then secure the tensioner over as far as possible.
  2. Install the timing belt cover.
  3. Install the accessory drive belts.
  4. Refill the cooling system and reconnect the negative battery cable.

Yeah on that vehicle there is a 90 degree plastic elbow that goes from the belt tensioner to the intake manifold and on both ends there are O-rings. Definitely need to repair this as soon as possible. Not sure your technical abilities but you would need to remove the serpentine belt and alternator and a bracket if I'm not mistaken. Usually takes me about 45 minutes to repair but I have been doing it for awhile. Good luck and Happy wrenching!!!
