Lower radiator hose or core


Before you go replacing a radiator, you need to check out why the quick overheat. Most likely due to low coolant which indicates a leak. Yes the core could be leaking...but it is not the most likely problem. If there is coolant dripping from the lower hose, it could be a simple matter of the lower hose clamp just needing to be tightened. They do work loose occasionally. Check the clamp, and tighten if needed. With the vehicle cold, check and refill the coolant in the both the radiator and the reservoir bottle. Run the vehicle to normal temperature and observe all connection points. IF no leaks are seen, use the vehicle normally and monitor coolant level for a week or so to ensure that you have solved the problem. If you are still loosing coolant, but have no visible signs of loss (drips or puddles under vehicle), then the problem could be a worn out water pump. They often tend to leak only when running and the lost coolant often evaporates on the engine block out of sight.

Coolant leak, unknown location


There is a compression tester for the radiator. It is a special cap that fits on and you pump it up. This will allow you to look for the leak with the engine cold and not running.

Upper radiator hose keeps leaking coolant, replaced the cuff ring but still seems to leak after a few days from the cuffed end of the hose. Does it need a new hose?


if it is leaking where it connects to the radiator it might be the radiator itself. take it to a shop and they can pressure test. some shops won't even charge for test.

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.

Coolant is leaking ,i have to fill it everyday.hardly any heat. what can i do? it seems like its shooting the coolant out somewhere on the right side of the motor.


It's probably the waterpump, it's right where you describe. They are pretty cheap and easy to do so even if you have a shop do it, it should not cost that much. Have it repaired before the engine is damaged from over-heating.

RAdior is leaking badly what do I do? One of the hoses seems to be broken, and seems like a huge leak on the bottom??? Need help asap contact me at downloadkris4free@hotmail.com


  • Turn off the engine as soon as you suspect a leak, to prevent the engine from overheating.
  • 2 Determine which radiator hose is leaking and exactly where the leak is coming from by looking for wetness.
  • 3 Purchase 1 gallon of antifreeze and the correct replacement radiator hose from your local auto-parts store or dealer. (Radiator hoses are not interchangeable. They come in specific sizes and shapes for your particular car model.)
  • 4 Wait for the engine to cool down for at least 20 minutes, before beginning any work on the cooling system.
  • 5 Place a large pan or wide bucket on the ground under the hose to catch the coolant.
  • 6 Use a screwdriver to loosen the hose clamps at both ends of the hose you are replacing.
  • 7 Remove the radiator hose by twisting and pulling where it connects to the radiator and engine. If the hose won't budge, use a utility knife to cut it off the fittings.
  • 8 Remove the hose clamps from the old radiator hose and slide them onto the new hose.
  • 9 Put the new radiator hose on. Spray the inside of the hose ends with WD-40 if the hose is hard to get on. Tighten the hose clamps.
  • 10 Refill the radiator and the coolant reservoir with a 50-50 mixture of water and antifreeze.
  • 11 "Burp the cooling system" by running the engine with the radiator cap off until the engine warms up. Keep the engine running until both the upper and lower radiator hoses feel warm (this indicates that the thermostat is open and the coolant is flowing through the entire system). Burping the cooling system allows any air bubbles to escape. Add coolant to the radiator as needed.
  • 12 Look for leaks. Inspect around the hose clamps for dampness. Tighten the hose clamps if there is any wetness.
  • 13 Put the radiator cap back on.
  • 14 Check the coolant level after driving, to ensure there are no leaks

    I heard a squiky noise like some kinda old belt rotating, then it stop. 2 miles later i saw temp rise. i pulled over and antifreeze was splatter from the top of radiator.


    Check the radiator hoses for a leak. The splatter was most likely the coolant/anti-freeze leaking from one of the hoses. Loss of coolant would make the temp rise and the engine overheat. If the hoses are good, look for seepage around the waterpump. These are the main causes for coolant loss.

    Overheating and leaking coolant


    Get yourself a pressure tester. Make sure everything is as dry as possible, use compressed air if available. Top off the radiator and hook up to tester. Pump up not to exceed the psi on the cap. Then listen carefully and look with a light. If it's mainly on top of the engine, keep an eye on the intake gasket area and any hoses. This is your best bet of finding the leak, because trying to find it with the engine running can cause burns and you can't hear it leaking.
