Subaru Forester Radiator Service Malaysia

The Subaru Forester SJ (2013–2018) and SK (2019+) are popular AWD SUVs in Malaysia using the FB25 2.

Subaru Forester Radiator

Forester FB25 radiator: aluminium core with plastic tanks; Malaysia heat puts sustained load on cooling system; inspect radiator for external leaks and core fin damage at every major service; coolant flush every 80,000 km
Forester radiator leak points: plastic tank-to-core seam common leak point on older Forester at 120,000+ km; lower radiator hose fitting can crack; inspect for coolant stain (green/orange residue) around tank corners
Forester e-Boxer cooling: e-Boxer has main coolant circuit AND separate inverter coolant circuit; inverter coolant (different colour) requires separate level check; do not mix inverter coolant with engine coolant
Forester overheating: if temperature gauge rises above midpoint — pull over immediately; do not continue driving; check coolant level when cool; overheating on Subaru boxer can cause warped head — very expensive repair
