1996 Dodge Ram leaking above the water pump below the thermostat but neither one of them are the problem what can it be


It's the bypass hose. It's a short hose that runs from the intake manifold to the water pump and is hidden under the bracket that supports the alternator and a/c compressor. Remove the alternator, unbolt and move the a/c compressor to the side, then remove the bracket to gain access to this hose.

Tip

Intake Manifold gasket replacement and/or leaking= Ford


Intake Manifold gasket~

Replacing intake manifold gasket:
Replacing the intake manifold gasket, I used the tube kind, it's a make it youself for about $6 (it's blue and the consistancy of toothpaste) follow directions carefully! You can get a tube at Autozone or any car parts store. Has been working great. Just ask the cashier for the make it yourself kind of intake manifold gasket. Sorry, I don't remember the name of it, it's been that long...lol...

As for the Intake Manifold leaking coolant....It could, but shouldn't. One of the largest problems I've seen for coolant to leak out the Intake Manifold has been due to pressure in the system somewhere... Check the classic area:
Water pump- look for either water seapage and/or coolant. You'll know if it is because you will see real water either coming out of the water pump leak hole or under the thermostat. Most of the time coolant will pool where your heater hose runs in the intake manifold.

Mentioning heater hose. Check for leaks, holes, and/or cracked heater hoses. In-addition to the water pump, heater hoses...Check the transmission system, exhaust system, fuel system, radiator system, A/C system, secondary fan (located above the water pump housing), and thermostat.Also, check all electrical connections....Hummm....This is almost the entire workings of the vehicle.

NOTE: "It seems to be an infinity kinda thing... Once one thing starts to fail and is ignored, you are bound to be fixing a chain of event failures. Therefore, Do not ignore even the smallest problem or you'll be bound for life in repairs...."

I am loosing water when poured into radiator right behind the tension pully on my 1994 chevy camaro out of a small hole could this be a freeze plug blown out


Water will pour out from a dislodged frost plug. You most likely have a leak from the water pump or intake manifold gasket. Also, check your heater hoses and water pump by pass hose for leaks.

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.

Grand Marquis LS 2004 smoking under hood on drivers side what is possibility of being gasket? no broken hoses ..not short on oil. no leaks..no radiator or heater problems. ..brand new thermostat installed...


This model uses a composite (some would say plastic) intake manifold, which has been known to develop cracks in the area of the thermostat housing. In addition, the water pump has a pipe to the back of it that emerges in the rear of the intake manifold. Both of these areas peculiar to this motor are known to leak coolant. In its history, many of these plastic manifolds had to be replaced, and there were even techinical bulletins from Ford on them. If you have leak in the tube or pipe that goes under the intake manifold to the back of the water pump, then you will likely want the dealer to fix it, as you may need a new water pump.
Two things then to watch: 1) coolant level and color and 2) any signs of leakage behind the main serpentine belt in the area of the water pump.
Since the serpentine belt is large on the 4.6L motor, and due to its rotation, it is possible that you only have a bad water pump and that the liquid is being thrown by the rotation of the motor. The water pump is not a difficult repair, as it comes off with only a few cap screws. However, if it is detached from the rear inlet pipe (as I mentioned above), it would require that the manifold be removed for it to be reattached. This is not a difficult job, but is very time consuming.

My truck just started blowing antifreeze from the right side of the motor under the alternator i pulled the brackets off the front and the water pump but i could not locate where it was coming from what...


If that is a 318 or 360 V8 check the small hose from water pump to the intake manifold they had a habit of developing a leak and it can spray over towards the alternator.
it is a short L shape hose from water pump to intake manifold.
Also check heater hose under the alternator for leaks or cracks.

Torque sequence for 1996 chevrolet van intake manifold with a 4.3 litre moter


Ha, you tried to fool me with the bit about a 3.5 L motor--I could find that one...here is the complete procedure from AutoZone.com:




Installation To install:
  1. Clean the gasket mounting surfaces. Be sure to inspect the manifold for warpage and/or cracks. If necessary, replace it.
  2. Position the gaskets on the cylinder head with the port blocking plates to the rear and the This Side Up stamps facing upward. Then apply a 3 / 16 in. (5mm) bead of RTV sealant on the front and rear of the engine block at the block-to-manifold mating surface. Extend the bead 1 / 2 in. (13mm) up each cylinder head to seal and retain the gaskets.

  3. Install the lower intake manifold. Tighten the bolts in sequence and in 3 steps, as follows:


    1. Step 1: 26 inch lbs. (3 Nm).
    2. Step 2: 106 inch lbs. (12 Nm).
    3. Step 3: 133 inch. lbs. (15 Nm).

  4. Install or connect the following:

    Power steering pump Alternator bracket bolt near the thermostat housing Wiring harness to the lower manifold components, including the injector, EGR valve and ECT sensor Air conditioning compressor bracket-to-the lower intake manifold pencil braces
  5. Install transmission oil dipstick tube, if necessary.

    Fuel supply and return lines to the rear of the lower intake
  6. Temporarily reattach the negative battery cable, then pressurize the fuel system (by cycling the ignition without starting the engine) and check for leaks.
  7. Disconnect the negative battery cable.
  8. Install or connect the following:

    Heater hose to the lower intake Upper radiator hose to the thermostat housing Distributor assembly and engage the wiring Ignition coil Connect vacuum hoses to the upper and lower intake manifold. New upper intake manifold gasket, making sure the green sealing lines are facing upward Upper intake manifold Manifold retainers. Tighten them to 88 inch lbs. (10 Nm) using two passes. Purge solenoid and bracket Brake booster vacuum hose at the upper intake manifold PCV hose to the rear of the upper intake manifold Vacuum hoses to both the front and rear of the manifold assembly Throttle body Throttle linkage to the upper intake Wiring to the upper intake components including the TP sensor, IAC motor, MAP sensor and the fuel meter Engine cover Air intake assembly
  9. Connect negative battery cable.
  10. Refill the engine cooling system.
  11. Start the engine and check for leaks.

Hello, i have a coolant leak i thought it was the water pump but the leak is above the mount bolt of the water pump beside the valve cover no coolant has gone in the valve interior, could it be a cracked...


A crack in that area of the block, while possible, is highly unlikely. A crack in the block usually happens in between the cylinder walls on the side of the block. It is most likely leaking from the intake manifold gasket that connects the intake manifold to the heads, or if the upper radiator hose connects to the intake manifold, it could be leaking from the thermostat housing or hose. There are also coolant temperature sensors that are mounted in that area. Or last but not least, it could be leaking from one of the freeze plugs in the end of the head. Coolant runs through the block, heads and intake manifold.

Leaking alot of water /coolant


You have answered your own question almost. You will need to jack the car up and inspect everything being that its 91 camara, there is defintely enough room to inspect everything. You either have a hose leak, a radiator or water pump leak. Only inspection will find that out. Thank you,
