The Truth About Radiator Sealers for Your Car

TLDRRadiator sealers can be effective in fixing leaks, but it's important to use the right sealer for the specific type of leak. Sodium silicate sealers are great for head gasket leaks, but caution is needed to avoid mixing with engine oil. Modern radiator sealers like Blue Magic Seal Up can work well with all types of antifreeze or pure water. Flushing the cooling system and using the sealer with pure water are crucial steps. Always check for coolant in the engine oil before using sodium silicate sealers to avoid engine damage.
