Cooling and Lubrication Systems
Avoid high-cost diesel engine repairs down the road with regular maintenance for your diesel engine's cooling system. Maintaining an effective cooling and lubrication in high performance Duromax, Power Stroke and Cummins diesel engines is the key to adding life to glow plugs, injectors, and turbos. Call 951-367-7400 today!

Glow Plug Replacement
Is your glow plug failing to ignite fuel from your fuel injector? Your truck or jeep depends on its glow plug in all types of weather and road conditions to create the heat and electrical resistance needed to start your engine. Come to Protrans Automotive & Transmission Specialists to replace a failing glow plug and get your truck or jeep cranking again. We offer the right glow plug for Duromax, Power Stroke Cummins diesel engines including DieselRX, NGK and more!

Injectors and Turbos
Since 1992, Protrans Automotive & Transmission Specialists is Riverside's best diesel repair shop. We repair worn-out high-performance injectors and turbos in GM, Chevy, Dodge and Ford trucks that create unwanted noise or blow exhaust. A failing injector can cause poor fuel economy, glow plug issues, and sluggish performance that can affect your truck or jeep on and off road.

Jeep and Truck Diesel Exhaust Repair
For any diesel truck or jeep your exhaust system consists of one or more critical pipes that directs exhaust gases away from the internal combustion engine and out into the air. Your exhaust system can be modified to increase engine performance, modify muffler sound, or reduce pollution. To get the most from your diesel GM, Chevy, Dodge or Ford truck or Jeep, you need regular maintenance on your exhaust system. For exhaust repairs to pass an emission test or for mods and upgrades, call 951-367-7400 or visit Protrans Automotive & Transmission Specialists today at 3420 Gato Ct, Riverside, CA, 92507.

Good Day; The service at "Protrans" was "Top Notch "! Before I took my car to "Protrans", I took it to another service center and I was told that it needed a Transmission Replacement to the tune of $3,500.00. I then took it to "Protrans" for a second opinion and their tech found that all that was needed was for the front wheel bearing to be replaced. That was a savings of over $3,000.00 dollars! So if you need ANY work done on your automobile I would have "PROTRANS" check it out first.
