Problems:
Brake fluid leak
Hydraulic brake systems rely on brake fluid to function. Leaks can occur in the brake lines, master cylinder, or calipers, leading to reduced braking performance.
Brake fade
Over time, the hydraulic brake system can experience brake fade, where the braking power is reduced due to overheating of the brake components, especially during prolonged or heavy braking.
Abs failure
The Anti-lock Braking System (ABS) can malfunction, leading to the ABS warning light coming on and potentially affecting the car's ability to prevent wheel lockup during hard braking.
Master cylinder failure
The master cylinder in a hydraulic brake system can wear out or fail, leading to a spongy brake pedal or loss of braking power.
Engine misfire
V-shaped engines with electronic fuel injection, like the one in the 1991 Ford Explorer, can suffer from misfires due to issues with the fuel injectors, spark plugs, or ignition system.
Head gasket failure
V-shaped engines are prone to head gasket failures, which can lead to coolant leaks, engine overheating, and reduced engine performance.
Timing chain wear
The timing chain in a V6 engine can wear out over time, leading to poor engine timing, rough running, or even engine failure if it breaks.
Fuel injector problems
Electronic fuel injection systems can develop problems with the fuel injectors, such as clogging or leaks, leading to poor engine performance, reduced fuel efficiency, and rough idling.
Intake manifold gasket leak
The intake manifold gasket can develop leaks, causing air and coolant to mix, which can result in poor engine performance and overheating.
Oxygen sensor failure
The oxygen sensors in the exhaust system can fail, leading to incorrect air-fuel mixture readings and affecting the engine's performance and fuel economy.
