How Is It Made?

Most modern cars use aluminum composite radiators, where the core is aluminum and the side tanks are reinforced plastic.
These radiators are made by brazing thin aluminum fins to flattened aluminum tubes.

Why Does It Fail?

Failure to service the coolant is a primary reason for failure. As coolant becomes more acidic over time, it consumes the aluminum core from the inside out.
Age is a common culprit in the final days of radiators.
Heavy use and being exposed to the elements wear down radiators.
Corrosion, salt and humidity cause a radiator to fail over a period of time.
When corrosion or contamination starts to form, it will slowly decrease the radiators capabilities until it breaks down completely.
Collisions can also cause radiator failure, especially if the underhood becomes tighter due to impact. At Platinum Plus Auto Repair Centers we can provide a replacement and get you back on the road.
