Your car’s engine is a complex machine that relies on a delicate balance of fluids to run smoothly. One of the most critical components of this system is the coolant reservoir, which stores the antifreeze mixture that circulates through your engine to prevent overheating. However, like any other part of your vehicle, the coolant reservoir is not immune to damage, and cracks can develop over time due to exposure to extreme temperatures, corrosion, or physical impact.
Ignoring a crack in the coolant reservoir can lead to serious consequences, including engine damage, costly repairs, and even accidents on the road. In fact, a cracked reservoir can cause the antifreeze mixture to leak out, leading to a decrease in engine performance, overheating, and potentially even engine failure. This is why it’s essential to address any issues with your coolant reservoir promptly.
In this blog post, we’ll guide you through the process of fixing a crack in your coolant reservoir. You’ll learn how to identify the signs of a cracked reservoir, what tools and materials you’ll need to repair it, and step-by-step instructions on how to seal the crack and prevent further damage. By the end of this article, you’ll be equipped with the knowledge and confidence to tackle this repair on your own, saving you time and money in the long run.
We’ll cover the following topics in this post: identifying the signs of a cracked coolant reservoir, preparing for the repair, applying a sealant to the crack, and reassembling the reservoir.

Identifying and Assessing the Crack in the Coolant Reservoir
Understanding the Causes of Cracks in Coolant Reservoirs
A cracked coolant reservoir can be a serious issue in a vehicle, as it can lead to coolant leaks, overheating, and potentially catastrophic engine failure. There are several reasons why a coolant reservoir might crack, including:
Extreme temperatures: Exposure to extreme temperatures, either hot or cold, can cause the plastic or rubber components of the reservoir to become brittle and crack.
Age and wear: Over time, the reservoir can become brittle and crack due to the natural aging process of the materials used to make it.
Physical damage: Drops, collisions, or other forms of physical trauma can cause the reservoir to crack or break.
Signs and Symptoms of a Cracked Coolant Reservoir
A cracked coolant reservoir can exhibit several signs and symptoms, including:
- Leaking coolant: If the reservoir is cracked, coolant may leak from it, leading to a decrease in the engine’s ability to cool itself.
- Overheating engine: A cracked reservoir can cause the engine to overheat, as the coolant may not be able to circulate properly.
- Warning lights: Modern vehicles often have warning lights that will illuminate if the coolant level is low or if the engine is overheating.
Assessing the Severity of the Crack
Before attempting to fix a cracked coolant reservoir, it’s essential to assess the severity of the damage. This can be done by:
Inspecting the reservoir for other signs of damage or wear.
Checking the coolant level and condition.
Using a flashlight to illuminate the crack and assess its size and location.
Tools and Materials Needed
To fix a cracked coolant reservoir, you’ll need the following tools and materials:
- A replacement coolant reservoir (if necessary)
- Repair epoxy or sealant
- Plastic repair putty
- A drill or sandpaper (for smoothing out the area around the crack)
- A cleaner or degreaser (for cleaning the area around the crack)
Preparing the Reservoir for Repair
Before attempting to repair the crack, you’ll need to prepare the reservoir for the process. This includes:
Draining the coolant from the reservoir.
Removing any debris or dirt from the area around the crack.
Applying a cleaner or degreaser to the area around the crack. (See: You Add Coolant Reservoir Radiator)
Allowing the area to dry completely before proceeding with the repair.
Repairing the Crack
Once the reservoir is prepared, you can begin the repair process. This may involve:
- Applying repair epoxy or sealant to the crack, following the manufacturer’s instructions.
- Using plastic repair putty to fill in any gaps or holes around the crack.
- Allowing the repair material to dry and harden according to the manufacturer’s instructions.
