Water Pump Failure<\/strong><\/p>\nThe water pump is an important component in the 5.7 Vortec engine cooling system. The water pump is necessary for circulating coolant throughout the engine to prevent overheating. You might have to deal with an entire water pump failure or just water pump leaks.<\/p>\n
The water pump shaft is the common failure point for the pump itself, though you need to watch out for the water pump gasket as it is a common leak spot. Gaskets naturally wear down with time and when this happens, they will start dripping coolant into the belts. This will limit the coolant going to the engine leading to overheating.<\/p>\n
As the gasket wears down, the pressure in the system will drop pushing the water pump to work overtime to ensure that enough coolant flows through the engine. The extra effort could cause the water pump to fail. Water pump issues are more likely to happen many years after you’ve used the engine. The symptoms could be engine overheating or you might notice leaking coolant.<\/p>\n
With a gasket leak, simply replacing the gasket will solve the problem. However, if the water pump is up to age, then you should consider replacing the pump as well.<\/p>\n
Bent Pushrods<\/strong><\/p>\nThe 5.7 vortec engine features pushrods that could bend when the engine revs past the redline. The higher the revs, the higher the lifters push the pushrod to let more air into the cylinder. If the lifter lifts too much, this can create a gap between the lifter and the pushrod which can cause the pushrod to tilt out of place.<\/p>\n
Then the lifter comes down while the pushrod is out of alignment causing it to bend. This can cause the piston to run into valves especially when the pushrod bends too much or snaps. The end result is serious internal engine damage. They can also rub against the guide holes of the cylinder head which will wear down the head and lead to a cracked head.<\/p>\n
When these start to happen, you will notice a ticking noise from the engine, poor idling, or cylinder misfires. If you notice that your pushrods are bent after a vehicle inspection, it is recommended that you replace them immediately to prevent significant engine damage.<\/p>\n
Pushrods aren’t really expensive to replace and in most cases, you will only have to replace the pushrods only. In other cases, the valves and piston will have to be replaced especially if the rod snaps. Due to these reasons, getting the pushrod replaced even if you notice only a slight bend is highly recommended.<\/p>\n","protected":false},"excerpt":{"rendered":"
