All 2 Known Issues
The Subaru Loyale uses the EA82 flat-four engine, which is the predecessor to the EJ-series engines that became famous for head gasket failures. The EA82 head gaskets deteriorate with age and heat cycling, causing external coolant leaks, internal coolant-to-oil contamination, or combustion gas leaks into the cooling system. The flat-four (boxer) layout means there are two head gaskets, and both typically need replacement. The EA82 is otherwise a durable engine that can last well over 200,000 miles with proper maintenance.
Common Symptoms
- External coolant leak from head gasket area
- Overheating under load
- White exhaust smoke
- Milky residue on oil filler cap
- Coolant level dropping without visible external leak
How to Fix
The Subaru Loyale is highly susceptible to body and underbody rust, especially in salt-belt regions. The wheel wells, rocker panels, rear quarter panels, and underbody are the most common rust areas. The Loyale was a budget vehicle with minimal corrosion protection from the factory. Many Loyales have been scrapped due to structural rust despite having mechanically sound drivetrains. The AWD system components (rear differential, driveshaft) can also suffer from corrosion-related issues.
Common Symptoms
- Bubbling paint on wheel wells and rocker panels
- Rust perforation on rear quarter panels
- Floor pan rusting through
- Subframe and crossmember corrosion
- Failed safety inspection due to rust
