Cranks slow only when engine is cold S70 1998

Check the battery voltage while cranking. Unless weather is very cold it should be 8.5-9 volts or more. If low, battery is weak or primary connections are corroded, or starter is drawing excessive current. The engine electronics might not tolerate an extremely low cranking voltage (like 5-6 volts) possibly explaining long cranking time. I would bet on a weak battery since the connections or starter are likely to be worse when hot, while battery is likely to be worst when cold.

If battery is weak, it could be defective or else your charging system is not keeping it well charged and needs to be checked or both.


Do you have the correct grade of oil in the engine?
