Alliant Power

Alliant Power serves Windsor and surrounding Wisconsin communities as a diesel engine repair specialist, earning a 4.4-star rating across 79 customer reviews. The shop operates Monday through Thursday from 7:30 AM to 5:00 PM, handling diagnostics, rebuilds, and repairs for diesel vehicles including Chevrolet Duramax, Ram Eco Diesel, and Ford diesel platforms. Technicians at this facility work on both light-duty pickup diesel engines and larger diesel power systems, addressing issues ranging from routine fuel filter service to complex injection pump reconstruction.

What distinguishes Alliant Power from general auto repair shops is their focused expertise in diesel-specific systems. Reviewers highlight their ability to diagnose problems that other shops misidentified, including cases where customers purchased incorrect or defective diesel components. The facility handles injection pump rebuilding, head gasket replacement, and turbo diesel applications, with one reviewer specifically noting their work on a 6.5 turbo diesel engine that another shop could not resolve.

Customer experiences at Alliant Power reveal a team willing to take on challenging diesel repairs. One reviewer described how technicians diagnosed a 6.2 non-turbo pump installed in a turbo 6.5 application that other companies failed to identify. Another customer noted Calvin and his mechanic performed head gasket work on a 2005 Silverado Duramax in subzero temperatures, completing the job with thoroughness. A stranded traveler on I-90 heading to the Twin Cities described being welcomed without an appointment on a Friday afternoon when dealership diesel technicians had already left for the day.
