Debuting for the 2007 model year, the first-generation Ford Edge brought transatlantic proportions, a supple long-distance ride and expansive five-seat luxury to the crossover segment. Essential Ford Edge maintenance is critical to ensure this substantial cruiser delivers dependable performance, offering an effortless motorway mile-eater that competes with the Toyota Highlander and Lexus RX rather than nimble European compact SUVs.
Propelling the Edge is the smooth 3.5-litre Duratec 35 Cyclone V6 engine paired with a 6F50 six-speed automatic transmission in front-wheel-drive or all-wheel-drive configuration. However, this engine features a notorious design flaw: an internal water pump driven by timing chain located behind the front timing cover. When the internal pump seal fails, coolant dumps directly into the engine crankcase, rapidly creating milky sludge that destroys engine bearings if not spotted immediately. Additionally, AWD models suffer from PTU all-wheel-drive transfer case fluid cooking due to its small fluid capacity and proximity to exhaust catalytic converters.
