Listed for drivers in and around San Marcos, CA, these 24 shops list coolant flushes and antifreeze service. What each one says about the coolant types it stocks, machine flushes and warranties comes from its own website; ratings and quotes come from public reviews.
Online booking is offered by 9 of the 24 shops. Put your engine and the coolant specification in the notes when you book, since the shop needs the right fluid on the shelf before you arrive rather than a universal jug under the counter.
