Troubleshooting Some Common Problems You Might Have With Your Truck
Your truck may go several years before it needs any repairs or maintenance, but once it begins to act up, you want to address those needed fixes as soon as possible. Putting off that work can mean more expensive fixes down the road, and the risk of your truck shutting down, even while driving. Note a few common problems you might have with your truck so you know what part might need replacing and what you may be facing by way of repair bills.
First, check that there is proper airflow through the front grill; an oversized truck can mean a larger grill that may easily grab and hold bugs and other debris. Cutting off this airflow can allow the engine to overheat.
Next, check the fanbelt to ensure the fan is operating properly and moving freely; replace it as needed. Dragging brakes can also cause the engine to work harder and overheat; put the truck up on blocks and have a friend apply and release the brake pedal, so see if the brakes release completely. If not, the callipers may need replacing.
Struggles to start
If the truck sputters, the fuel pump might be failing; this can cut off the regular supply of fuel to the engine. The fuel filter may also be clogged, so that the fuel supply becomes intermittent. This can also mean contaminants building up in the gas tank, and dirty or contaminated fuel can cause the engine to sputter or struggle to start.
The air filter may also need changing; clogged air filters starve the engine of the oxygen it needs to create proper combustion. Note, too, that the battery connections to the starter may be corroded, so the battery is fully charged but the starter is not getting the power it needs to work. That wiring may need replacing.
Black smoke usually means that oil is burning; if the truck has an oil leak, it may need a new oil pan or oil hoses. Dirty air filters can also cause a build-up of fumes and emissions, so the engine produces black smoke as it runs.
Blue smoke usually means worn piston rings that sit above the piston chambers; these should be changed immediately, as this can mean too much air in the engine so that it struggles to create combustion. White smoke from under the hood may mean the engine is overheating; check the thermostat and fan to ensure they're working, and the level of radiator fluid or coolant. If the radiator has a leak, the engine can easily overheat and create white smoke.
