Seeing the SPN 2011 FMI 9 fault code? It signals a communication loss with your ABS module. This guide walks you through the most common causes, like bad wiring or power loss, and provides a simple step-by-step process to diagnose and fix the problem.
Clogged radiator symptoms and how to fix them. Here’s a tip before you price out a new radiator—most clogs are repairable. It usually comes down to two things: crud blocking the fins on the outside, or rust and scale buildup inside choking off coolant flow. The main signs are pretty clear—temperatures creeping up under load, coolant dumping into the overflow tank, or cold spots on the radiator after it should be warm. This guide shows you how to confirm the problem step by step. Shine a light through the fins to see if they’re packed with debris, check what your coolant looks like, and rule out the thermostat, water pump, cap, and fan system before you pull the trigger. Clean external debris with low-pressure water or air, use a flushing product to break up internal deposits, and only replace the radiator if the flow doesn’t come back after cleaning.
Whenever you run into an electrical problem, the fuse box is the first place to look. In this guide, we’ll dive into the Ford fuse box diagram with the example of a Ford F150 to help you better know the fuses in your Ford trucks.
Inner and outer tie rod: which one is worn out? The outer tie rod usually goes first—it’s exposed to mud, water, and rocks. The inner end sits tucked under a rubber boot, so it lasts longer. This guide helps you figure out which one is causing your steering trouble without guessing and changing the wrong part. Learn the 3-and-9 o’clock test to check for play, how to inspect both joints, and which symptoms point to each failure—clunking over bumps usually means outer, while vague steering or shimmy at speed points to inner. Replace both sides together, count the turns, and always get a wheel alignment after the job.
If your machine’s battery keeps dying, a parasitic draw is the likely culprit. This guide explains the signs and shows you how to test for parasitic draw with a multimeter. Follow our simple steps to find the faulty circuit yourself.
Without a differential, driving would be extremely difficult.The role of differentials is to allow the wheels on the same axle to rotate at different speeds. This is particularly important in turns, as the outer wheels need to rotate faster than the inner wheels, since they have a greater distance to cover in the same amount of time. Without a differential, the inner wheel would lose traction and could cause the vehicle to skid. The tyres and drivetrain would be under high stress, not to mention the loss of control in corners.
This guide details common transmission speed sensor symptoms like rough shifting, power loss, and incorrect speedometer readings. A faulty sensor sends bad data, leading to poor performance and potential transmission damage. Learn what causes failure and why a quick fix is crucial.
Carburetor vs Fuel Injection: What Works Best for Your Operation? Fuel injection starts easily in the cold, burns less fuel, and doesn’t care about heat, cold, or heavy loads. But if you’d rather keep repairs cheap and simple, a carburetor is still a solid call. Fuel injection adapts better to changes in temperature and load. Carburetors are easier to clean and fix with hand tools. EFI costs more up front but saves you trouble later. Carbs are cheaper and simpler, though they need more looking after. What’s best depends on your machine, what you’re willing to spend, and how much fussing you’re okay with. In maintenance, this choice comes down to uptime, repair bills, and keeping the machine ready to go when you are.
Here are 11 common engine knocking causes:
Low-octane or poor fuel quality: Octane is a measurement that tells you how resistant a fuel is to abnormal combustion. If you use a lower octane than recommended by your vehicle owner’s manual, the fuel can pre-ignite and cause engine knock.
Low motor oil levels or poor oil quality: Insufficient or degraded engine oil can increase friction and heat inside the engine. Higher operating temperatures can contribute to abnormal combustion and increase the possibility of knocking.
Excessive carbon buildup: Gasoline contains carbon, which can leave deposits and buildup on critical engine components like the combustion chamber surfaces. Over time, carbon deposits accumulate on pistons and valves, reducing space inside the combustion chamber and raising pressure and heat. Then, pre-ignition and knocking become likely
Uneven cuts and shaking are signs your deck needs help. This John Deere mower deck repair guide shows you how to fix cracked spindle mounts, replace worn pulleys and belts, and sharpen blades for a better cut and longer equipment life.
SPN 636 FMI2 signals a fault in the crankshaft position sensor circuit. The FMI2 suggests that the electronic control module (ECM) has detected an abnormal signal from the sensor, which could lead to poor engine performance, misfires, or difficulty starting the engine. In this guide, we’ll dive into the symptoms, causes and easy fixes of the error code.
Bad ignition switch symptoms: how to tell if it’s failing? No crank?No crank? Starts then stalls? The catch is, a weak battery, a starter on its last leg, or a wiring glitch can pull off the same act. This guide takes you through the usual warning signs—no crank, starts and stalls, dash power cutting in and out, a key that doesn’t turn smoothly, or power suddenly returning when you move the key—and helps you sort out whether it’s the switch, the battery, or the starter. We’ll also walk through what to check before you replace anything: battery voltage, terminal connections, ground straps, fuses, and the connector for heat damage or corrosion. Look at the whole pattern—one symptom alone doesn’t tell the whole story.
