Frequently Asked Questions
Which engine brands do you service?
CAT, Cummins, Detroit Diesel (including DD15), Volvo and other major commercial diesel platforms.
What is an overhead / overhaul service?
An in-frame rebuild of major internal engine components without pulling the full engine. See our Specials page for current overhead service pricing.
Can you diagnose fault codes roadside?
Yes, our mobile units carry diagnostic equipment for most common fault codes and can often make the repair on-site.
How do I know if I need an overhaul?
Persistent power loss, high oil consumption or repeated internal engine faults are common signs — call us and we'll run diagnostics first.
