1. Solder Bloom:
 Solder corrosion caused by degredation of rust and leak inhibitors
in antifreeze. Tube to header joints are weakened and corrosion can
restrict coolant flow. |
2. Internal Deposits:
 Rust and leak inhibitors can form solids that collect in the
cooling system and restrict flow. |
|
3. Fin Deterioration:
 A chemical deterioration of the fins most often caused by road salt
or sea water. |
4. Fin Bond Failure:
 A loss of solder bond between fins and tubes. Fins are loose in
core causing loss of heat transfer and reducing radiator strength. |
|
5. Tube-To-Header Leaks:
 Failure of the solder joint results in coolant loss. |
6. Leaky Tank-To-Header Seam:
 Solder joint failure or a cracked header is generally the result fo
pressure-cycle fatigue. |
|
7. Blown Tank-To-Header Seam:
 An indication that the radiator has been subjected to extreme
pressures resulting from exhaust leaking into the cooling system. |
8. Loose Side Piece:
 Can lead to flexing of the core and radiator tube failure. |
|
9. Leaky Oil Cooler:
 Coolant shows traces of oil. Transmission or engine damage can
result from the mixing of coolant with transmission fluid or engine oil. |
10. Leaky Inlet/Outlet Fitting:
 Leaks in this area can be caused by fatigue or solder joint
corrosion. |
|
11. Fan Damage:
 |
12. Over pressurization:
 Excessive pressure in the radiator caused by a defective pressure
cap or engine exhaust leak can destroy the radiator. |
|
13. Electrolysis:
 Stray Electrical current can cause excessive corrosion of metal
components. |
14. Electrolysis:
Stray electrical current can cause an electrochemical reaction that
will produce voids in tubes. |
|
15. Cracked plastic tanks:
 High stress in the radiator can cause premature plastic-tank
failure. |
16. Steam Erosion:
 Steam can break down the plastic tank which will produce thinning
and ultimately holes in the plastic tank. Frequently, white deposits are
also found. |
If you are having problems with your radiator, please make an
appointment to have your vehicle serviced.
