Warhawk Mobile Mechanic has been in business since 2009, serving customers in San Antonio, TX and the surrounding areas. We’re fully insured, and owner Ruben Trevino has 10 years of experience in automotive, diesel, heavy equipment, and aircrafts. We offer a long list of services along with a 3-month warranty on all our work. Our business name and logo were inspired by the values of integrity and

honesty. WWI biplanes used the Screaming Chief logo, and Warhawk was the name of the plane used during WWII to help fight against the Occupations. All of the people who flew those planes volunteered to fight. After working for larger companies, Ruben Trevino decided to start his own business so he could honor these values. At Warhawk Mobile Mechanic, we work one-on-one with customers in order to provide a personalized experience and an affordable alternative to hefty shop fees.

3rd times the charm right? EVERY TIME I have purchased a 1/2 electric impact they have been stolen. The 1st time somebody broke into my truck and stole all my impacts including the brand new never used 1/2 inch. The second time was when I was working in Puerto Rico in 2017 on generator with FEMA, they shipped my service truck there and I bought my second 1/2 inch impact. When the mission was over they shipped my truck back state side and the shipping company ransacked my service truck and stole over 10k in tools…..including my brand new never used 1/2 inch impact 😒 I’m kind of nervous how this is going to turn out lol

I was scrolling through some picture and came across this panel I did a few years back for a customer. My customer was a second owner of this beautiful Monaco Knight RV. He hired me to do a bunch of upgrades to the cooling packs and while I was doing that job he hired another guy to do some “upgrades” to the inside and one of those up grades was adding switches for various items. One night he was watching tv and smelt something burning he quickly found the hack wiring and direct load being wired to the switches. The next day he asked me if I could fix the mess he found so I did and made this panel with the correct load rating relays and fuses. I layed and crimped each wire by hand from relay to fuse blocks it came out great

Had a customer drag in a CAT 252 skid steer that was a no crank no start. After diaging it I found some relays that were changed out with the wrong type and allowed water intrusion. After fixing that issue and putting in the correct relays I labeled them for the customer and did a full PM and rebuilt one of the bucket tilt cylinders. After that she was sent back into the field!
