Coolant leak after alternator replaced

Hello, Dave here, contributing to RepairPal and providing expert advice since 2010. If you truly think the shop that did the work caused a problem, bring it to their attention so they can resolve it. It sounds to me like you might have an air pocket in the cooling system. The coolant may need to be added and air purged. If you have a continuing coolant leak, a pressure test of the cooling system is a good first step to see where the leak is coming from. Hands on testing is needed. https://repairpal.com/auto-repair-near-me Click the link or call us at 877-913-1554. We'll gladly find you a certified RepairPal shop in your area.
