Tri-Valley Automotive is now doing Diesel Service and Repair


If you have a Ford Powerstroke, F250 or F350 with the 6.0 or 6.4 turbo, Chevy Duramax, 2500 or 3500 with the 6.6, or Dodge Ram 2500 or 3500 with the Cummins 5.9 12 Valve or 24 Valve, we can help keep it running smooth for you.


We have engine oil, filter and fuel filter services that can keep the Injectors and Injection pumps sludge free and properly lubricated. This will also help protect the EGR system from buildup and keep the oil cooler clean. Your engine will run cooler and it will restore lost power due to plugged cats. It will not harm the particulate filter.


We are also qualified to do most repairs that you will need along the way. Hard starting due to glow plug issues, overheat problems, transmission servicing, excessive smoking, or worn brakes.
