I just had the fan clutch of my GMC K15 replaced two weeks ago. However, it creates a loud noise every time the motor reaches around 2700 rpms. I wonder if there is something wrong with the replacement. I've never heard the noise it's currently making before. My truck is also accelerating up to 30 mph whenever I shift it into gear. What should I do to get rid of the noise and fix this?
This could be due to the replacement of the fan clutch. If your mechanic installed a heavy duty fan clutch on your truck, then it might be locking up wrongly to your vehicle. You need to bring your vehicle back to the repair shop to have the fan clutch checked or fixed. In the future, remember that you need to use only the correct replacement part for the fan clutch and not a heavy duty one. It needs to be compatible to your vehicle, so don't just settle for any replacement part. You can find these details in your owner's manual.
I noticed that the fuel consumption of my GMC K15 recently has been higher than ever. I wonder if my fuel tank is leaking, or there's a problem with my engine. I searched online and found that it could be due to a faulty fuel pressure regulator. I purchased an original equipment manufacturer (OEM) regulator online, and thought I could do the replacement on my own. Where is this part located?
You can find the fuel pressure regulator on the fuel meter body, which is under the upper intake plenum. You need to remove the upper intake to replace the regulator. It is held in with a clip, and there is no vacuum hose to it. It is important to change this part when it has already failed because of its function. It is important in ensuring fuel economy and good performance. When this part fails, you might notice various symptoms, like rough idling, emission of black smoke, and strong stench of gasoline. If you experience a stalling engine or gasoline dripping from the tailpipe, then it is getting worse. Don't let it reach this point, and replace it immediately.
I've been having problems with my vehicle's oxygen sensor lately. The Bank1 Sensor1 is getting errors. I need to have it replaced, but I don't know if it's on the driver's side of the engine or not. Where should I look for it, and what does it mean?
Any problem with your oxygen sensor should be addressed immediately. The Bank1 Sensor1 is on the driver's side, mounted to the exhaust in front of the catalytic converter. Make it a point to double check the wire harness and inspect it for any signs of damage or premature wear. You need to replace the sensor in case you find that it has already failed. This part is responsible for helping your engine to run smoothly and minimize the emissions. When this part fails, your truck will perform poorly and consume more fuel.
