Volvo S70 Tune-Up Procedures


Volvo sold the S70 from 1998 to 2000 with a range of inline five-cylinder engines. Base models have a 2.4-liter engine producing 168 horsepower, GLTs have a turbocharged version of the same engine with 190 horsepower, and top-of-the-line T5s have a highly tuned, 2.3-liter turbocharged engine that produces 236 horsepower. All engines have a 90 mm stroke, a double-overhead cam design and multi-point fuel injection with four valves per cylinder.

Capacities and Pressures – The crankcase of the S70 holds 6.1 quarts of oil, including what’s in the filter. On turbo models, add .95-quart if the oil cooler has been drained. The turbocharged engines’ cooling systems contain 7.4 quarts; the non-turbo contains 7.6 quarts. The fuel pump should produce 42.6 PSI of pressure and pass a volume of 1.4 pints in 30 seconds at 68 degrees Fahrenheit with the engine off, bypassing the fuel pump relay. The compression ratio is 10.3:1 for the naturally-aspirated engine, 9:1 for the 2.4-liter turbo and 8.5:1 for the 2.3-liter turbo.
