[QUOTE="sakuraguy, post: 984677, member: 6441"] Causes of Radiator Failure While there are certainly dozens of causes of radiator failure, here are sixteen of the more common causes. If you notice a degradation in radiator performance or obvious signs of damage (noise, steam, etc.) then you may need a radiator replacement. You will want to take your car's radiator to a professional but be sure to visit RadiatorNet when it comes time to purchase a new radiator for your engine. Tube-to-Header Leaks Failure of the radiator solder joint on a radiator header and tubes can result in coolant loss. Steam Erosion Steam can break down the plastic tank and this can produce thinning and ultimately holes in the radiator's plastic tank. Solder Bloom Solder corrosion caused by rust and leak inhibitors in radiator antifreeze. Tube-to-header joints can then be weakened and corrosion can restrict radiator coolant flow. Over Pressurization Excessive pressure in the radiator caused by defective pressure cap or engine. An exhaust leak can ultimately destroy the car's radiator. Loose Side Piece Can lead to the flexing of the core as well as radiator tube failure. Leaky Tank-to-Header Seam Failure of the solder joint can eventually lead to radiator coolant loss. Leaky Oil Cooler If radiator coolant shows traces of oil, engine damage can result. The mixing of coolant with any transmission fluid or engine oil can damage radiators. Internal Deposits Rust and leak inhibitors can form solids that slowly collect in the radiator cooling system and eventually restrict flow. Fin Deterioration A chemical deterioration of the radiator fins is often caused by road salt or sea water. Fin Bond Failure This is a loss of solder bond between fins and tubes. Fins loose in radiator core can cause loss of heat transfer and reduce radiator strength. Fan Damage A minor collision or a failed water pump can eventually result in radiator damage. Electrolysis (External) Stray electrical current can cause an electrochemical reaction that will produce voids in the radiator tubes and cause radiator damage. Electrolysis (Internal) Stray electrical current can cause excessive corrosion of the radiator's metal components. Cracked Plastic Tanks High stress in the radiator can cause premature radiator plastic tank failure. Blown Tank-to-Header Seam If the radiator has been subjected to extreme pressures resulting from exhaust leaking into the cooling system, damage can occur. Leaky Inlet/Outlet Fitting Leaks in the radiator inlet/outlet area can be caused by fatigue or solder-joint corrosion. [/QUOTE]
