30/60/90K Mileage Maintenance
As time goes by, various auto repair and maintenance needs come up at different intervals. Most manufacturers recommend car maintenance in intervals of 30,000 miles. This is the 30/60/90K mile schedule (issued by the manufacturers to car owners). Trust the experts at A.G.

  • Inspection of parts and systems - gears, tires, brake pads, belts, hoses, etc.
  • With higher mileage: spark plugs, belts, timing belts when applicable

Belts
A fan belt, also known as a drive belt, is a belt connecting your car's engine to the front mounted accessories. The fan belt rotates the water pump and engine fan, which maintains a cool environment for the engine and its components. Sooner or later, your vehicle's fan belts will dry out and crack. When you are ready for a replacement you can count on A.G. Automotive & Diagnosis for all your vehicle's repair needs.

You not only have to get the belts replaced with quality ones but you should have the work done by experts. To have the belts replaced by auto cooling and heating experts - and get your car driving right - visit A.G. Automotive & Diagnosis today. The mechanics at A.G. Automotive & Diagnosis will thoroughly inspect your car's belts; replace all worn belts; and adjust the installed belts.

Check Engine Light
No one likes to see their car's "Check Engine" light come on. The light could mean a costly problem, like a bad catalytic converter, or it could be something minor, like a loose gas cap. At A.G. Automotive & Diagnosis, we can pull the code and diagnose the problem for you. Give us a call at 818-280-3969 or stop by the shop for our expert assistance.

Factory Recommended Service/Maintenance
Automotive and auto parts come with a factory recommended service and maintenance schedule. The manufacturer will tell you how often to service or replace an auto part. At A.G. Automotive & Diagnosis, we offer factory recommended service/maintenance. Our highly skilled auto mechanics offer comprehensive knowledge and experience. At A.G. Automotive & Diagnosis, all your factory recommended service/maintenance needs are handled with the latest diagnostic equipment. Remember, we work on all American and imported vehicles (either diesel or gas engines).

Headlight and Bulb Replacement
To maintain maximum visibility (and keep you safe), you should always make sure that your vehicle's headlight bulbs are in good working condition. Although replacing faulty headlight bulbs is a simple and quick process (takes very little time), you need to rely on an experienced auto mechanic to handle your headlight and bulb replacement. This way, you will have quality bulbs installed by experts. Remember, it is a critical part of your car's maintenance and your safety. For all your headlight and bulb replacement needs, call or visit A.G. Automotive & Diagnosis today.

Hoses
Hoses transfer coolant and antifreeze throughout the engine's cooling system (including the radiator). Sooner or later, your vehicle's hoses will dry out and crack. When you are ready for a replacement you can count on A.G. Automotive & Diagnosis for all your vehicle's repair needs.

You not only have to get the hoses replaced with quality ones but you should have the work done by experts. To have the hoses replaced by auto cooling and heating experts - and get your car driving right - visit A.G. Automotive & Diagnosis today. The mechanics at A.G. Automotive & Diagnosis will thoroughly inspect your car's hoses; replace all worn hoses; and adjust the installed hoses.

Oil, Lube, and Filter
To keep running smoothly, your car highly relies on oil, lube, and oil filters. Oil helps in lubricating, cooling, and cleaning the internal engine components. With time, motor oil becomes contaminated. Your car needs an oil, lube, and filter change every three months (or 3,000 miles). When it is time for a lube, oil, or filter change, take your vehicle to A.G. Automotive & Diagnosis in Reseda, CA 91335.

Wiper Blade Replacement
Visibility is very important to safe driving. Having properly functioning wipers can help keep you safer on the road. If your car's wipers are not wiping well or are leaving lines, have them replaced immediately. To have wiper blades fitted on your vehicle, call 818-280-3969 or visit A.G. Automotive & Diagnosis today. We will fit your car with high quality and effective wiper blades.

-Tawnya P.

"I had an oil leak and I could have been taken advantage of very easily...but they were honest and told me it was a simple fix, and I walked out paying less than originally quoted. I understand every business has to make money to strive, but I can see they value their integrity over making a quick buck. They've gained my respect and future business. I highly recommend this company!"


-Roxanne R.

"I found this AG Automotive through yelp. So I decided to give it a try. I sent in one of our inventory (2006 Ford Crown Victoria Police Interceptor) in for steering wheel stiffness diagnostic. Owner Chuck was able to identify the problem in the first place. His crews are very professional (more professional I thought I was at a car dealership service department). Great experience throughout. Most importantly, got the job done right. They know what they're talking about. Certainly not some BS mom & pop shop just there for your money (if they fixed it right the first time). Price is fair. If you ever have problem with the repairs they done, there's always a warranty to back you up. Thank you chuck. I will be back at your shop for our other vehicle recondition. From: Ideal Motor Group in San Gabriel Valley."


-David L.

"I went here with a really bad brake problem. Chuck took the time to explain the cause of the issue and what could be done to not only fix it but how to prevent it in the future. He and his team are professional and highly knowledgeable. I feel confident and grateful to these guys. I definitely recommend this shop and will continue to refer friends and family here. His prices are more than fair and the work is top shelf."
