Automotive vehicles run on all kinds of fluids, and we are not just talking about gasoline. In addition to that fuel source, the vehicles' veins flow with coolant, which regulates the temperature of your engine and other systems. Sometimes, though, coolant can freeze when conditions are extremely cold. Too much heat in the engine can also cause gases to expand within. Both can lead to cracks in the engine block, from which coolant can leak.
These problems are potentially catastrophic for any car, and the owner may need to replace the entire engine block. However, concave expansion plugs may be the only solution you need. If the holes are shallow enough, you can stick these parts inside and create a cover that never comes off. It may take a little work, but being able to provide customers with an inexpensive and permanent solution makes it worthwhile.
Every auto shop should have plenty of concave expansion plugs at their disposal, and Boltman has more than enough to offer. Our online superstore features over 60 different kinds of expansion plugs for a variety of vehicle makes and models.
