About S&S Diesel Repair
S&S Diesel Repair operates as a dedicated diesel engine repair service in Montebello, California, maintaining a 4.7-star rating compiled from 80 customer reviews. The shop maintains standard weekday hours from 8 AM to 6 PM, with Saturday availability by appointment and Sunday closure. This business focuses exclusively on diesel-powered vehicles, serving owners of light-duty and heavy-duty trucks powered by diesel engines.
The facility distinguishes itself through specialized expertise with three major domestic diesel platforms: Ford Power Stroke, GM Duramax, and Cummins engines. Their service catalog addresses common diesel-specific concerns including diesel particulate filter maintenance and glow plug replacement, representing repairs that require different technical approaches compared to gasoline-powered vehicles. The shop advertises comprehensive diagnostic and repair capabilities, positioning their service range from headlight to tailpipe coverage.
Customer feedback identifies Kumar as a technician who takes time to explain repair requirements and keep clients informed throughout the service process. One reviewer described bringing a truck that two previous shops could not repair, with S&S Diesel successfully diagnosing a faulty fuel rail component. Another customer noted the shop provided options for California-compliant upgrades to turbo and EGR cooling components while explaining long-term benefits. The technical staff accommodates customers unfamiliar with diesel technology, offering patient guidance alongside the repair work.
What Customers Say
Reviewers frequently mention honest communication and transparent explanations of repair needs. Five-star reviews highlight the shop's ability to diagnose issues that other facilities could not resolve, with several customers noting Kumar by name for his patience with customers who lack diesel technical knowledge. The most common praise points are diagnostic accuracy and willingness to explain repair options rather than simply performing the most expensive solution.
