Engine: 1.8L K8-DE (V6, DOHC)

Manual Transaxle (G25M-R)

The Mazda MX-3, despite its reliability, has a number of weaknesses typical of cars of its time. The main problems are related to age, design features and operating conditions.

1. Engine and transmission:

Oil leaks:

Valve cover gaskets and crankshaft seals are common leaks.

The problem is typical for K8-DE (V6) and B6-DE (1.6) engines.

Engine overheating:

A clogged radiator or faulty thermostat can cause overheating, especially on older cars.

Timing belt wear on 4-cylinder engines:

The timing belt needs to be replaced every 80-100 thousand km to prevent engine damage.

Automatic transmission problems:

Older automatic transmissions may have problems shifting due to worn solenoids or contaminated oil.

2. Suspension and steering:

Suspension knocking:

Worn stabilizer bushings, ball joints and shock absorbers often result in knocking noises while driving.

Steering rack noise:

The steering rack can wear out, which manifests itself as play or noise.

3. Electrical:

Central lock failure:

Lock mechanisms jam over time or fail completely.

Wiring problems:

Over time, contacts and connections oxidize, which can cause problems with lighting, windshield wipers and other systems.

Alternator malfunctions:

Old alternators often require replacement due to worn brushes or bearings.

4. Body and interior:

Corrosion:

Weak points: wheel arches, sills, underbody and tailgate (especially under the license plate).

Door Seals Wear:

Door seals lose their elasticity over time, which leads to wind noise and water ingress into the cabin.

Door Sagging:

Heavy doors can cause hinges to wear out over time, causing them to sag.

5. Braking System:

Brake Disc Wear:

Discs tend to wear out quickly with aggressive driving.

Caliper Seizure:

This occurs due to corrosion of the guides or untimely replacement of brake fluid.

6. Climate System:

Air Conditioner Malfunctions:

Refrigerant leaks and compressor failure are common problems on older MX-3s.

Weak Interior Heating:

The problem may be related to a clogged heater core or a faulty thermostat.

• Regular maintenance and use of high-quality consumables.
• Checking the body for rust and treating it with anti-corrosion compounds.
• Diagnostics of electrical systems and timely replacement of worn-out elements.
• Replacement of engine oil, transmission and brake fluid strictly according to regulations.
