If the leak looks like it's coming out the 90 degree black rubber elbow then, this is a common problem.

If its water, it has to be water and coolant. if its leaking, then is time to change it. just be sure to have the car to cool down before trying to remove that hose to replace it. its a easy change. you can go to a discount auto parts and have them figure out what exactly hose is.

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.

On the under side of the water pump there is a hole called a weep hole its there to let you know that the seal is leaking on the pump and will need to be replaced soon so you don't have a major failer on the highway and damage your engine

My 1990 toyota corolla is getting hot really fast - i fill radiator up and after 5-10 min the water has evaporated - it appears to be leaking somewhere around the right side of engine (facing front of car)...


Well there are only 3 things that could have gone wrong.

1. Radiator Leak - this means the radiator has developed a hole with via corrosion of the metal parts of simply integrity failure of the plastic parts of the radiator.
2. Hose leak - this could be a hole in 1 of 2 hoses that connects the engine to the radiator. Or it can also be a leak where the hose connects to the radiator (clamp Failure).
3. Water Pump breakdown - this is where the gasket in the water pump has failed and is leaking out the water rather than pumping it.

All the problems above has different ways of diagnosing. but we can probably narrow it down.

1. if the leak is near the radiator then it could be a hose connection, hose breakage or Radiator hole.

2. if the leak is nearer the engine then check the other end of the hose and if its not there then it could only be the water pump is leaking. You can check this if there are water stains on the water pump. The water pump on a 1990 corolla is mechanical turned also by a fan belt. Look for a pulley that has a hose connected to the radiator and that would be the water pump.

Ford mondeo 2002 Zetec 2.0 motor ..Have a small or slow water leak comming from front of motor behind water pump area ,above air con unit, where water hose goes into the motor ..very hard to see where it's...


Starting from the top down dab every joint and seam with kitchen paper towel. Between each dab and press examine the kitchen towel for dampness. It is vital that you find out exactly where the leak is coming from. You could be lucky and the leak might be fixed buy an extra half turn on a jubilee connector on a hose union or a quarter turn on the water pump or thermostat housing bolts. If the leak persists you may require a new gasket . If the leak is from the water pump shaft seal behind pulley you will see a tell tale stain on the 'chin' of the pump body. This will require a replacement of the pump.

Anti freeze/coolant leasking from the front lower part of the engine, is this the end of my motor???? Its 2000 LHS w/3.5 ltr. V6, thanks.


It sounds from what i can make out that it's leaking from your water pump and will need to be replaced if you mean the engine of the engine where the serpentine belt is. Before you go replacing the water pump, inspect the hose clamps first to ensure that you cover all bases. Good luck and keep me posted, and don't add any radiator stop leak. They just clog up the coolant jackets and restrict the flow of coolant.

Water drippinjg from above serpentine belt where lower radiaotor hose connects. water is not coming from hose coming from the silver piece


That is your thermostat gasket. Easy and cheap to replace. If you do it you might as well just buy a new thermostat since the cover will be off and they are cheap.

1987 HONDA ACCORD LX WATER LEAK


Yes, there is a "bypass outlet" coolant hose that connects from the water pump inlet pipe (metal pipe that runs from back of water pump along engine block to lower radiator hose) to the intake manifold.

I am not sure about the "black box" - not enough detail.
