The N52 was the first water-cooled engine to use magnesium/aluminium composite construction in the engine block. [1] It was also listed as one of Ward's 10 Best Engines in 2006 and 2007. [2] [3] [4] In European markets, the N52 began to be phased out in favor of its direct injected version, the BMW N53 in 2007. Markets such as the United States ...
However, once water boils, it is an insulator, leading to a sudden loss of cooling where steam bubbles form. Steam may return to water as it mixes with other coolant, so an engine temperature gauge can indicate an acceptable temperature even though local temperatures are high enough that damage is being done. An engine needs different temperatures.
The engine temperature on modern cars is primarily controlled by a wax-pellet type of thermostat, a valve that opens once the engine has reached its optimum operating temperature. When the engine is cold, the thermostat is closed except for a small bypass flow so that the thermostat experiences changes to the coolant temperature as the engine ...

Some of that coolant can be diverted through the heater core to give some engine heat to the cabin, or adjust the temperature of the conditioned air. A heater core is a small radiator located under the dashboard of the vehicle, and it consists of conductive aluminium or brass tubing with cooling fins to increase surface area. Hot coolant ...

Several markets outside Europe only offered a small subset of models in the estate body style. In the United States and Canada, the only estate model available prior to 2007 was the 325xi, [24] and then the 328i and 328xi from 2007 onwards. The Australian market received only a handful of models which included the 320i, 320d and 323i until the ...
There are three versions of the engine, 1.4 L (1,397 cc), 1.6 L (1,598 cc) and supercharged 1.6 L (1,598 cc). BMW complained about the performance of the engine. According to Ward's Auto, Erich Sonntag of BMW described the Tritec engine as old fashioned and not very effective on function, performance and fuel efficiency .
