1978 Chevrolet Pickup problems

Common 1978 Chevrolet Pickup problems

The 1978 Chevrolet pickup is known for its reliability and durability, but like any vehicle, it can experience certain problems over time. Here are some common issues based on complaints from owners of this car:

• Coolant Leaks or Oil Leaks From Intake Manifold Gaskets: This issue is common in Silverados and Sierras made between 1999 and 2007. The intake manifold gaskets may leak coolant or oil, which can lead to significant engine damage if not addressed promptly. Replacing the gaskets can be a complex and expensive repair, costing approximately $1,000 to have done by a mechanic.

• Restricted Secondary Air Injection Valves: The secondary air injection check valves in Silverados and Sierras made between 1999 and 2007 may become restricted, leading to reduced airflow and causing the check engine light to come on. Fixing this problem requires replacing the check valves. Even if the fault code shows that the problem is only occurring with one bank of cylinders, it is recommended to replace both to avoid having the other one go out on you as well.

• Failed Steering Wheel Position Sensor: A common problem in Silverados and Sierras made between 1999 and 2007 is a failed steering wheel position sensor. This issue can cause a service stability message to appear on the dashboard, and may occur intermittently or more regularly, such as every time the truck is started or the wheel is turned. Replacing the sensor, which costs approximately $200 to $300, should fix this issue.

• Failed Starter Motor: Some owners of 1978 Chevy pickups have reported issues with the starter motor, where the starter turns fine when not bolted in, but as soon as it is bolted in, all they get is a click and the truck does not start. This issue may be caused by a faulty starter motor or a problem with the electrical system.

• Sluggish Engine Performance: Some owners have reported issues with the engine running sluggishly, especially when backing up a hill. This issue may be caused by a variety of factors, including a clogged fuel filter, a dirty air filter, or a problem with the ignition system.

It is important to note that these issues are not necessarily exclusive to the 1978 Chevrolet pickup and may be found in other models and years as well. If you are experiencing any of these issues with your vehicle, it is recommended to consult with a certified mechanic to diagnose and repair the problem.
