Gates Engine Coolant Thermostat P/N:34858
Gates 34796 thermostat for the 2002-2003 Volvo S60 5-cylinder 2.4L, the 2002-2004 S60 5-cylinder 2.3L, the 2003-2009 S60 5-cylinder 2.5L, the 2005-2009 S60 5-cylinder 2.4L and other vehicles regulates coolant temperature to help the engine run more efficiently. This Gates thermostat, also called an engine coolant thermostat, is an integrated housing unit.
A thermostat that sticks or opens late can show up as a temperature gauge reading high or low, a slow warm-up or coolant seeping at the housing. Before you replace the thermostat, rule out a coolant leak elsewhere, a worn water pump or a faulty gauge or sensor; a shop can test the cooling system. Each engine has a single thermostat, so one unit per engine is all it takes.
The 2002-2003 Volvo V70 5-cylinder 2.4L, the 2002-2004 V70 5-cylinder 2.3L, the 2003-2007 V70 5-cylinder 2.5L, the 2005 V70 5-cylinder 2.4L and the 2003-2007 Volvo XC70 5-cylinder 2.5L all fit it, along with the S60 above and more Volvo models. It meets or exceeds OE standards for fit, form and performance. If your Volvo is not named here, look up its year and engine in the "Vehicles it fits" section.
