Inner Guard Corrosion
Symptoms
Rust in the engine bay around the inner fenders and strut tower bases.
Cause
Road spray enters the engine bay and collects in the double-skinned areas around the inner guards. Heat cycling from the engine accelerates corrosion.
Fix
Clean, treat, and seal if surface rust.
Cut out and fabricate if perforated.
Cost: $800--2,000 per side for significant repair.
