Before purchasing an engine block sealer, here are some important factors to keep in mind:

3. Effectiveness – Look for reviews or ask for recommendations from other car owners to determine how effective the product is in fixing leaks permanently.
4. Price – Engine block sealers come at different price points. While it may be tempting to go for the cheapest option, remember that quality comes with a price.

1. Read Instructions Carefully – Each product has its own set of instructions on how to use it properly. It is crucial to follow these instructions carefully for optimal results.
2. Prep Work – Before applying the sealer, make sure to clean and degrease the affected area thoroughly for better adhesion.
3. Do Your Research – Take time to read reviews and ask for recommendations from trusted sources before making a purchase.
