    The BMW 3-Series was developed by the German carmaker as a successor of their 02-Series. Originally, the vehicle was available exclusively as a 2-door coupe, while later the convertible version was added to the range. The first model year for this automobile was 1975, while in the United States the 3-Series appeared only two years after the official release. The American version of this BMW car featured certain differences from its European sibling. To meet the emission control regulations, the power output of the engine was decreased. Front and rear bumper bars were enlarged and headlight assembly was switched to sealed beam lights, while side reflectors and indicator lights became larger.

    A thermostat is a very important component of the vehicle’s engine cooling system. When the water in the inner cooling circle gets hot enough, the thermostat opens and allows the water from the outer cooling circle to circulate through the system. If the thermostat of your German automobile won’t open, the engine may get overheated, which will lead to further damage. If you’ve faced issues with the engine cooling system and are shopping for a BMW 3-Series thermostat, you’ve come to the right place! In our online catalog you will find everything to restore your BMW car and put it back on the road.
