RepairPal Certified shops can diagnose and repair your 1991 Mazda MX-6. They provide transparent pricing with a minimum 12-month or 12,000-mile warranty on repairs and services.
Is there any maintenance that is required for that
Just to make sure it doesn't develop a leak and that it is working so if you need it.
