Gates Engine Coolant Thermostat P/N:34700
Gates 34047 thermostat for the 2002-2006 Audi A4 4-cylinder 1.8L and other vehicles regulates engine temperature through an integrated housing. This engine coolant thermostat is a bolt-on unit with its own insert and seal.
A thermostat that sticks or opens at the wrong time can show up as overheating, slow warm-up or coolant seeping at the housing. Before you replace it, rule out low coolant, a leaking hose or a faulty temperature sensor, since any of those can look the same.
It fits the 2002-2006 Audi A4 4-cylinder 1.8L and the 2002-2005 Audi A4 Quattro 4-cylinder 1.8L, and each takes one. It meets or exceeds OE standards for fit, form and performance.
