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 641-324-9988 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 Knudtson Automotive Services 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 2013, Knudtson Automotive Services is Northwood'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 641-324-9988 or visit Knudtson Automotive Services today at 616 Central Ave, Northwood, IA, 50459.
