How To Stop Coolant Leaking From Engine Block in 3 Minutes

Coolant leaking from your engine block is a very complicated issue. You might assume it is from the radiator without knowing it comes from your engine block. I will quickly show you a proven permanent fix to stop coolant leaking from engine block.

The major cause of leakage from engine blocks is a result of a crack from any part of the engine block. And due to the nature and build of the engine block, this is always a major issue.

When it comes to car maintenance, some tasks are more difficult than others. Keeping tabs on engine coolant is one of the trickier tasks. Coolant leakage from the engine block is a common problem with older cars and can be challenging to spot in time. Here are some tips for how to stop coolant leaking from your engine block before things get any worse.

What is an Engine Block Crack

Today, we’ll discuss fractured engine blocks, how they occur, and your available solutions. Because of the material, your engine block is comprised of, a cracked engine block is such a major concern. The most common solution for broken metal is to weld it back together.

This is regrettably not feasible with your engine block. Cast iron cannot be welded because it differs in some ways from the majority of carbon steels. The intense heat required to weld most metals is sufficient to damage cast iron and leave the surrounding region startlingly weak and brittle after the welding.

There are several methods to get a crack in your engine block. First, overheating can cause engine blocks to break. Too much heat will cause bolted joints and mating surfaces to expand and shrink to the point where the faces will begin to break.

Extreme cold weather, on the other hand, has the potential to break your engine block. In the winter, excessively low temperatures can cause the coolant in your engine to start to freeze, whether it is due to the incorrect antifreeze and water ratio or you just live in a very cold climate. Water expands as it freezes, which might cause your engine block’s walls to move enough to break.

Causes of Engine Block Crack

Your engine block can turn out to be cracked in a few distinct places. First, you could spot coolant leaking outside. If you discover coolant drips but no gasket, seal, or hose leaks, your engine block could be damaged. Make sure your leak isn’t only being caused by a leaky freeze plug in this situation! In certain circumstances, you can also have an internal engine leak caused by a fractured engine block.

In this scenario, coolant will be present in your engine oil, causing it to turn milky white or light brown.

This might be disastrous for your engine since watery oil is a terrible lubricant and can soon start to corrode and damage important engine-bearing surfaces. The last possibility is that your cylinder may have a fractured engine block. It can be quite challenging to diagnose an engine block with this sort of crack that exhibits the same symptoms as a blown head gasket.

Common Engine Block Leakage Places in Cars

To stop Coolant Leaking From Your Engine Block, you should be aware of the common places where cracks happen on an engine block, then continue with your diagnosis.

Coolant is leaking from the bottom of the engine

If you see bubbles of coolant rising to the surface of your engine block, it’s a sure sign that there’s a leak. A leak from the bottom of the engine block is the most common type of coolant leak.

It’s caused by a crack in the block casting or engine head gasket. A crack in the block casting is usually the result of corrosion or an uneven repair. If you’re driving an older car with a cast iron engine block, it’s important to check the engine block regularly for signs of corrosion.

Coolant leaking from the front of the engine block

If you see coolant leaking from the front of the engine block, it’s likely to be a failed engine head gasket. An engine head gasket leak is more associated with aluminum engines than cast iron engines.

Engine head gasket leaks are notoriously difficult to detect, especially in the early stages. They’re often easy to miss but can cause catastrophic damage to your engine if left unchecked, as well as lead to engine overheating.
