Radiator Problems

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:

A minor collision or a failed water pump can result in radiator 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.
