CLEAN COOLING FIRST LINE fills VITAL NEWS in on electric water pumps and how to keep them in good shape. In efforts to reduce engine emissions, many vehicle manufacturers are using electric water pumps instead of, or alongside their traditional beltdriven counterparts. Cooling component specialist First Line mirrors these market developments with the addition of 10 primary electric water pumps and 27 secondary electric water pumps. The primary pump effectively replaces the traditional, mechanical pump. The secondary pump is fitted alongside a mechanical pump and often has several auxiliary functions. Modern low-emission/high-output engines need to run within a narrow temperature threshold bracket to maintain their efficiency. Electric water pumps regulate coolant flow in accordance to the ECU’s (Engine Control Unit) specifications. Furthermore, forced induction engines require additional cooling of the turbo or superchargers after shutdown in order to prevent premature wear or damage. PRIMARY PUMPS Certain BMW, Lexus and VAG models are fitted with a primary electric water pump instead of the traditional belt-driven option. Due to the pump’s position, its exposure to heat and other extreme conditions, they often fail prematurely (sometimes, even before 100,000 miles). As with most engine components, specifications can vary between suppliers. It is crucial to fully understand the available aftermarket alternatives and realise that the internal makings may vary. Investing in quality replacement electric water pumps is strongly advised because solder can melt at around 180°C whereas a welded joint is more durable by offering strong joints. Therefore
