Problem: Smell of Burnt Rubber from Toyota Camry XV70

Symptoms:

A noticeable smell of burnt rubber, especially after driving.
Possible accompanying symptoms such as unusual noises (squeaking or grinding) when braking or accelerating.
No warning lights on the dashboard, but potential decrease in vehicle performance.

Diagnostic Steps:

Visual Inspection:
- Check for any visible signs of wear or damage on the belts, hoses, and tires.
- Look under the hood for any melted components, particularly around the engine and accessories.
- Inspect the wheel wells for any debris or materials that might be rubbing against the tires.
Tire Inspection:
- Examine all tires for signs of excessive wear, bulges, or foreign objects lodged in the tread.
- Ensure that the tires are properly inflated to the manufacturer's recommended pressure.
Belt Inspection:
- Inspect the serpentine belt and timing belt for signs of cracking, fraying, or burning.
- Check the tension of the belts to ensure they are not too loose or too tight.
Brake Inspection:
- Inspect brake pads and rotors for wear. Worn pads can cause a burning smell if they are excessively worn down.
- Check for any brake caliper binding or dragging, which can cause heat and smell.
Examine Engine Compartment:
- Look for any oil leaks that may be dripping onto hot engine components.
- Inspect the exhaust system for any signs of leaks or damage.

Tools Required:

Safety gloves and goggles
Flashlight
Tire pressure gauge
Torque wrench
Car jack and jack stands
Basic hand tools (sockets, wrenches)
Inspection mirror (optional)

Repair Instructions:

Step 1: Inspect the Tires

Remove the Wheels:
- Use a car jack to lift the vehicle and secure it with jack stands.
- Remove the lug nuts and take off the wheels.
Check for Damage:
- Inspect each tire for uneven wear or embedded objects.
- Replace any damaged tires with new ones.

Step 2: Examine Belts

Inspect the Serpentine Belt:
- Check for signs of wear and tear. If damaged, replace the serpentine belt.
- To replace:
  - Release tension using a belt tensioner tool or a wrench.
  - Remove the old belt and install the new belt according to the routing diagram usually found near the engine.
Check Timing Belt:
- If the timing belt is suspected to be damaged, it may require removal of engine components. Consult a service manual for specific instructions for your model.

Step 3: Brake System Inspection

Inspect Brake Pads and Rotors:
- Remove the wheel to access the brake assembly.
- Check the thickness of the pads. Replace if they are less than 3 mm.
- Inspect the rotors for scoring or warping. Resurface or replace if necessary.

Step 4: Engine Compartment Check

Look for Oil Leaks:
- Check around the oil pan, valve covers, and gaskets for leaks.
- Clean any oil residue and replace any leaking gaskets or seals.
Examine the Exhaust:
- Inspect the exhaust system for holes or damaged sections. Replace as needed.

Step 5: Final Check

Reassemble:
- Once repairs are made, reassemble any components removed.
- Reinstall the wheels and tighten lug nuts to the manufacturer’s specifications using a torque wrench.
Test Drive:
- After everything is put back together, take the car for a short test drive.
- Pay attention to any smells, noises, or changes in performance.

Conclusion: If the smell persists after these inspections and repairs, it is advisable to have a professional technician conduct a more thorough diagnosis as it could indicate deeper mechanical issues. Regular maintenance and inspections can help prevent these problems from occurring in the future.
