How Do I Troubleshoot a Toyota FWD Pickup for Free?
- 1). Ensure that all of the plastic interior panels are securely clipped in place if your Toyota is producing interior rattles under operation. Most interior panels are fastened in place by plastic clips, though larger panels may also be secured by Phillips head screws. Use the heel of your hand to bump the various panels in order to reproduce the rattling noises you hear while driving. This will allow you to locate any loose panels. Once located, ensure that the panel clips are tightly fastened, and tighten any securing Phillips head screws.
- 2). Inspect the air intake system at the front of your Toyota's engine bay for any signs of cracking or other damage. Damage to the intake system can lead to poor engine performance, as well as various air metering and emissions issues. Also ensure that any sensors or plugs into the air box and intake tube are securely connected.
- 3). Unfasten the clips that secure the plastic air box lid, and lift the lid free from the air box. Inside you will see the air intake filter. Examine the filter for any signs of damage or collected debris. Worn air filters can lower the performance of your Toyota, as the engine is not able to efficiently breathe air through the filter. Replace the filter with a new, factory unit if necessary, and reinstall the air box lid.
- 4). Examine all the various rubber lines routed throughout your Toyota's engine bay. These include intake vacuum lines, coolant lines, and/or various sensor connections. Since the engine produces high levels of heat under normal driving, rubber engine components are prone to cracking and breaking down over time. Damaged vacuum lines or intake system sensor connections can lead to various throttle issues, as well as lowered engine performance. Worn coolant lines are prone to bursting when the engine is in operation. Replace any worn rubber lines and connections with new, factory units.
- 5). Look for signs of smoke coming from the exhaust system when driving your Toyota. Generally, a smoking exhaust system indicates the development of more extensive engine issues. White smoke coming from the exhaust system is most often from the engine burning coolant, due possibly to a damaged intake manifold gasket or head gasket. Blue or black smoke most likely indicates that the engine is burning large amounts of oil, which can indicate a worn head gasket or damaged piston rings. Have your Toyota examined by a certified mechanic if the exhaust system produces smoke under operation, as such engine issues are likely to become more complicated if not repaired immediately.
