Re: Engine coolant level
When the engine is cold the coolant should be at or just above the low mark. You can add a 50/50 mix of coolant and water to the expansion tank.
You might also open up the cap on the heater exchanger WHILE THE ENGINE IS COLD and check the level. If you cannot see into the exchanger, you can use your finger to check. You should feel coolant before you feel the top of the coil inside the exchanger.
