What should I do today if my car won't start at the office?
If a jump start works but the car dies again, the alternator is the next thing to test. Call NOLA Mechanic at (504) 395-8968 and ask for a mobile visit at your downtown lot. Ask the pro to test both the battery and the charging system before any parts are ordered.
How much will an alternator job cost me?
Alternator replacement typically costs $200 to $600 with an aftermarket part when the alternator is easy to reach. Deeper installations run $400 to $800. Economy cars may run $450 to $700, and larger or smart alternator systems can reach $900 to $1,400.
How long will the repair take?
Easy-access alternator replacement usually takes 1 to 3 hours of labor. Deeper installations can take 5 to 8 hours. Because the repair usually takes a few hours rather than a full day, you may be able to return to work the same day.
What should I check before hiring a mobile mechanic?
Louisiana does not require a state-level license to work as a general mobile mechanic. Ask the pro for proof of insurance and relevant certifications. Ask for a written quote that lists parts and labor before work begins.
What to do next
- Jump-start the car and note whether it dies again within a few minutes; that points to the alternator, not just the battery.
- Ask the pro to run an alternator test and a battery load test in your parking lot before replacing any part.
- Request a written quote that separates parts from labor and states whether the part is aftermarket.
- Ask the pro for proof of insurance and any certifications, such as ASE for auto repair, before the work starts.
- Call (504) 395-8968 or email [email protected] for a free quote from an independent, insured mobile mechanic.
