About the shop
An independent diesel shop that acts like one
A&S Diesel serves San Jacinto, Hemet, Perris, Menifee & the San Jacinto Valley. We're small on purpose: the technician who diagnoses your truck is the one who repairs it, and there's no service writer in between translating the story.

Dealership training, shop-floor pricing
Our lead technician spent 20 years as a Ford Senior Master Technician, which is why Power Stroke work — 6.0L head gaskets and oil coolers, 6.4L radiators, 6.7L CP4 fuel systems, 7.3L injectors — gets diagnosed from experience rather than from a search result. Alongside him are ASE certified technicians who handle Duramax, Cummins and everything gas-powered that rolls through the door.
We invested in real diagnostic equipment because guessing is the most expensive thing a shop can do to a customer. Full-module scan tools, pressure testing, smoke testing and data logging mean the estimate you get is based on measurement, not on which part is easiest to replace.
And when your truck can't make the trip, free local towing is included with major repairs — one less reason to put off a repair that's only getting worse.
Show the work
Photos of the failed part, the measured value, the spec it should have been. If we can't show you why a repair is needed, we don't sell it.
One posted rate
$160.00 per hour for everyone — fleet, retail, first visit or twentieth. No shopping the customer.
Say no when it's right
Sometimes the honest answer is that the truck isn't worth the repair. We'd rather lose the job than sell you a rebuild on a rusted-out frame.
Legal builds only
No emissions deletes on registered vehicles. There's plenty of reliable power available without making your truck unregisterable.
