Hi,
That's good news. At least at this point, we don't have to worry about a head gasket. If you are smelling it in the vehicle, did you check to see if the heater core may be leaking? Feel the carpet on the passenger side to make sure it isn't leaking.
If there is nothing, the best thing to do is look for evidence of dried coolant at different connectors, the radiator, the intake, and so on. If nothing is noticed, then I would pressure test it. This is done when the engine is cold and gives you the chance to check things without getting burned. Plus, you will see if it holds pressure.
If it doesn't hold pressure and you are unable to locate a leak, the next step would be to get a dye for the cooling system. Drive the vehicle and then, with a specific type of light, check to see if there is any evidence.
Keep in mind, the water pump could be leaking as well. However, it's driven by the timing chain, and you really can't see it. Check at the bottom of the timing cover at the front of the engine as well.
Let me know if I can help in any way.
Take care,
Joe
