Dumb question... if you drive the vehicle to the retailer, how in the heck would the techs be able to do a compression check on a cold engine? Wouldn't the engine still be somewhat warm when they do the test, even if they let the car sit for a few hours?

Perhaps the warm (but not hot) Saturn specification reflects the reality that testing on a truly "cold" engine rarely happens?

From a tech perspective - what does a "cold" engine mean anyway?
