Welcome

Allen's Wrench is your dealership alternative. We have been doing automotive maintenance, and repairs in San Marcos for over 17 years. At Allen's Wrench, we employ highly trained technicians. Quality is our number one priority and we strive to get the job done right, at a price that's fair, the first time. 

We use factory parts, premium Kendall motor oil, and genuine manufacturer specific transmission oil.  Our customers have added peace of mind knowing that we stand behind our 12 month 12,000 mile warranty.

*Some services such as transmission replacement carry a 2 year, 24,000 mile warranty.

What We Do

Our services range from a simple oil change that can be done while you wait, to all factory scheduled maintenance including 30K, 60K, and 90K mile service intervals.

Other services we perform include air conditioning, electrical, brakes, engine mechanical repairs, transmissions, and engine diagnostics. We also accept all local dealership coupons.

Most services can be completed the same day when prescheduled. We also offer a local shuttle service. Please call ahead and schedule your appointment today.

"Being female, I dreaded going to mechanics because I would pay for service I didn't need and at a higher rate.
 
Since going to Allen's Wrench, I get the auto service I need.  They explain things in detail and charge a fair rate.
I never feel taken advantage of.  I referred Allen's Wrench to a friend and co-worker, who was very happy with the recommendation"
