Since 1978 we have been Maine's premiere drive-ability specialist

At Smith's Auto Tech, we clean fuel injectors as well as do fluid exchanges on transmissions, brake systems, cooling systems and power steering systems. We were the second shop north of Augusta to offer transmission fluid exchange services and first in the area to use the T-Tech Transmission Flush Machine. No other shop in the area offered fluid maintenance services before us.

Transmission Care Bangor Maine

Caring for your transmission

Protect your investment by performing routine transmission fluid exchanges. We recommend using vehicle specific fluid, and we do your fluid excahnge until it comes out clean to help maintain your vehicles warranty, and reliability.

Vehicle Fluids Bangor Maine

The right fluids can prevent costly repairs

Use of anything else other than what your vehicle calls for may/will cause damage, and void your vehicle's warranty.

We use ZDDP Maxx fluids in our oil changes.

Fuel Injections Bangor Maine

A dirty fuel injector can reduce performance

The most common problem with injectors is that they accumulate a buildup of wax, tar, and olefins inside the injector and on the pintle/seat area. These types of debris buildup will restrict the flow of fuel through the injector.

Engine Coolant Bangor Maine

Replacing engine coolant is reccomended

The reason for using new engine coolant is: Recycling anti-freeze may remove all particulate matter but the heavy metals from other customers' vehicles are still in the solution and they cannot be removed unless you distill the anti-freeze.
