Parts for the Toyota 4 Runner 4Y-EC

Known issues

Rust is the most significant problem. Check the chassis, body mounts, sills, and floor pans carefully. The 2.4L diesel (2L and 2L-T) engines are known to crack heads if overheated, so check for signs of coolant leaks or overheating. Front suspension components can wear quickly with heavy use, and steering idler arm wear is a common issue.

WOF tips

Rust is a critical WOF failure point. Thoroughly inspect the chassis, body mounts, sills, and floor pans. Pay close attention to suspension components, including ball joints, bushes, and leaf springs. Check the condition of the brake lines, hoses, and master cylinder. Steering components, specifically the idler arm and steering box, should be inspected for excessive play. Engine oil leaks, especially from the rear main seal, are common.
