There are some simple tools you can borrow from the major autoparts stores to find this leak. Although the leak can be someplace other than the Radiator, the device is a Radiator Pressure Tester.
You simply use a slightly warmed engine and remove the Radiator cap. Then look at the pressure rating on the old cap. Use the tool and pump some pressure into the radiator, not to exceed the rating on the cap.
If you have a leak at all on the outside of the engine, the pressure will force the water out of the leak and you can find and replace the bad part.
If you use it this way, it is quite simple. But bad things can happen inside motors. Sometimes their gaskets leak inside the motor and the water may go through the cylinders or into the oil. You will see the loss of pressure on the tool but see no fluids on the ground.
Often, the engine will run very rough when cold or may miss continuously from fouled sparkplugs. Do not worry about this worst case senario unless this is what your vehicle is doing. Contact us at Fixya for further advice once you discover your problems.
