My car air conditioning was broken, and they fixed it quickly, right before a heat wave. A month later it broke again, and they honored their warranty and fixed it immediately, free of charge. Everyone in the shop is friendly and knowledgeable, return customers are recognised when walking in the front door. I trust this shop and will return again if I have any more trouble with my car. - Erin H. (5 star review on Google)

Is your engine on the way out? If it’s already kicked the bucket, then case closed - however, there are a number of other indicators that your engine is about to go, even if it’s still running at the moment. From National Brake & Muffler in Griffin, GA, here are some signs of trouble that predict an imminent engine failure is in the cards for your car, truck, or SUV.

Just went in for a muffler repair, turned out to be a quick weld, once we waited for the car to cool down it didn't take any time at all. Only cost me forty bucks and stopped the excess noise, so yay! - Sean H. 

mechanic working on diesel engine

When you think about diesel engines, you probably think about large trucks and machinery, and maybe a few oddball cars over the years.  But how long has diesel really been around, and why is it used the way it is today? National Brake & Muffler in Griffin, GA has the answers you need to become more in-tune with your diesel truck and engine. 

Pile of tires

There are multiple types of tires on the market for almost every car, truck, or SUV. The type of tire you want depends on a variety of factors, from climate to how you drive. Here’s a short rundown of common street tires that’ll suit your needs.

Fleet cars, vans, and trucks see a lot of wear and tear. If your engine has already called it a day, then it’s obviously case closed - you need a new engine or a new vehicle. However, there are many times when an engine is about to go down, and you can get it taken care of before it kicks the bucket for good - saving you time and towing in the process.

Failed engine mounts are an irritating issue to live with causing your car or truck to vibrate and you don't know why. At National Brake & Muffler in Griffin, GA, we can help, no matter what type of car, truck, or SUV you drive and it is an easy issue to detect on a test drive.

There are a few indicators your engine mounts need to be replaced. For one, you can do a visual inspection, if they’re accessible enough - if they looked cracked, smashed, or dry-rotted, it’s probably time for new ones.  If the engine visibly shakes while it’s running, engine mounts are also likely the culprit.  However, if you are like most drivers you simply get in and drive on down the road until something is different or a light comes on!   Then you call our shop for help!
