It is generally known that to enable the vehicle to deliver maximum performance, engine temperatures should be kept within the proper range. However, maintaining the right temperature under the hood is also essential for long lifespan of your car in general and the engine in particular. Overheating is one the greatest threats endangering the engine, that is why efficient cooling is so critical. A thermostat is one of the key elements of the cooling system that regulates coolant flow. Usually, it is covered and protected with a housing that directs the coolant stream once the valve opens. Housings and filler necks help route the radiator hose in the right direction.
Cooling systems of the BMW 3-Series are generally known for being rather troublesome, with water pumps and thermostats being some of the common areas of failure. Consequently, overheating is a very common problem when it comes to BMW 3-Series cars, that often causes serious damage. If you plan a cooling system repair job, don’t forget to choose replacements from our selection of BMW 3-Series thermostat housing and filler necks.
