Most common problems:

Brake fluid leaks

Hydraulic brake systems rely on brake fluid to function. Leaks can lead to reduced braking efficiency or total brake failure.

Worn brake pads and rotors

Over time, brake pads wear down and rotors can become warped, leading to decreased braking performance and potential safety issues.

Master cylinder failure

The master cylinder is critical in a hydraulic brake system. Failure can lead to a loss of braking power.

Brake line corrosion

Corrosion in the brake lines can cause leaks or complete failure of the braking system.

Engine oil leaks

V-shaped engines, especially older models like the 1994 Chevrolet Blazer, are prone to oil leaks, which can lead to engine damage if not addressed.

Head gasket failure

High mileage V6 engines may experience head gasket failure, leading to coolant leaks, overheating, and engine damage.

Timing chain/belt wear

Over time, the timing chain or belt in a V6 engine can wear out, potentially causing engine misfires or catastrophic damage if it fails.

Fuel injector problems

V6 engines may develop issues with fuel injectors, leading to poor engine performance and fuel economy.

Ignition system issues

Older vehicles like the 1994 Chevrolet Blazer can experience problems with the ignition system, including worn spark plugs and faulty ignition coils.

Vacuum leaks

Vacuum leaks can cause rough idle, poor acceleration, and overall engine performance issues in V6 engines.

Cooling system failures

Overheating can be a common issue due to radiator, water pump, or thermostat failures in older models.

Exhaust manifold cracks

V6 engines, particularly older ones, can develop cracks in the exhaust manifold, leading to exhaust leaks and increased engine noise.

Fuel pump failure

Over time, the fuel pump may fail, leading to engine stalling or failure to start.
