Toward the front of your engine bay you will find your BMW 525i radiator. The 525i radiator is the central component of your car's cooling system. Your engine generates a tremendous amount of heat, and without some way to dissipate that heat, the moving parts of your engine would be damaged quickly.

Coolant fluid circulates through your engine to absorb heat, and your BMW 525i radiator removes that heat from the coolant so it can be recycled through the engine. The 525i radiator is actually a section of tubing with either vertical or horizontal fins that is connected by external radiator hose to tanks.

When the coolant and water mixture enters the BMW 525i radiator, it is dispersed through the tubes to create more surface area for the fluid. Outside air passing through your grille serves to cool the fluid in the 525i radiator. When your car is idling in place and air is not moving through the grille, the BMW 525i radiator fan kicks in to lower the coolant temperature and keep your engine from overheating. Typically, problems that develop with the 525i radiator are attributed to either leaks or blockages in the passages of the radiator. Leaks in your BMW 525i radiator can occur at or in the radiator hose, or in the body of the radiator itself as a result of rust or corrosion. Your 525i radiator may become blocked if it is not regularly flushed and cleaned, which can lead to a burst radiator hose.When you need to replace your BMW 525i radiator, browse our extensive online catalogue for high quality 525i radiators and radiator parts at great discount prices.
