Is there any harm to the glow plugs or the engine if I cycle the glow plugs 2 or 3 times before I start the engine when it is cold. I have been cycling them twice in this cold weather (15-20 degrees) and I think it really helps. The engine starts easily with not much smoke or knocking. I have lots of experience with Diesels but none with glow plugs. Thanks
