Firstly, consider the type of vehicle you own as different products may work better with certain models. Some products may be designed specifically for older vehicles, while others may be suitable for newer models.
Type of Leak
It’s also essential to determine the type of leak your heater core has. Some products are more effective for minor leaks, while others are designed for larger and more severe leaks.
Compatibility with Coolant
Check if the stop leak product is compatible with your car’s coolant type. Using an incompatible product can cause further damage and lead to costly repairs.
Ease of Use
Consider how easy it is to use the stop leak product. Some require professional installation, while others can be used by anyone without any special tools or skills.
