Pierburg water pump + MAHLE thermostat for BMW N54 and N55 engines


For BMW enthusiasts, we have put together a practical set of PW0014 pump of CWA 400 type in the best quality. The set includes Pierburg water pump 7.07223.02.0 and MAHLE thermostat TM1497.

The main advantage of Pierburg water pump 7.07223.02.0 is the use of better materials than the series pump. Vibrations in the plastic serial pump can cause the plastic cover to rupture which may lead to water leakage. That may eventually lead to an electrical short in the electrical components.

The Pierburg pump is made of aluminium and is designed to eliminate the problems of the original series pump and increase its reliability. The pump has undergone a stress test which has shown longer durability and better properties than a plastic pump installed in new cars in series production. The pump cover is made of aluminium which eliminates noise and makes the driving experience more pleasant.

The pump and the thermostat are designed for BMW 1, 3, 5, 6, 7, X3, X5, X6, Z4 and N54 / N55 engines. Related OE numbers are 11519455978, 11517632426, 11517588885, 11517568594, 11517563659 for the pump and 7544788, 11537544788, 7536655, 11537536655, 11537549476, 7549476 for the thermostat.
