Cylinder head distortion and coolant loss

Attaches to 2AD-FTV at engine level · Engine · carried by 2 variants across 2 chassis

Overview

Cylinder head distortion and coolant loss is a common fault recorded against 2AD-FTV at engine level, typically from 100–200k km. It shows up as coolant disappearing with no visible leak, the temperature gauge moving under load, and in later stages white exhaust smoke and overheating. Where it's documented, the repair runs €2,000–€4,000 (cylinder head replacement or rework at a specialist, costs dated 2026-07), and it can be partly checked before you buy. 2 variants across 2 chassis in this database inherit it.

What happens

Symptom. Coolant disappearing with no visible leak, the temperature gauge moving under load, and in later stages white exhaust smoke and overheating.

Cause. The cylinder head can distort where it meets the gasket, letting combustion pressure into the coolant. Toyota revised the head and extended warranty coverage in several markets, so which head is fitted matters more than the mileage.

Later parts. Revised cylinder head fitted under warranty programmes and in later production

Sources. Toyota extended warranty programmes in several European markets

How to check it

Paperwork

Check the coolant level and look for oil or residue in the expansion tank, ask directly for head or warranty paperwork, and treat unexplained top-ups as the fault until proven otherwise.

The last column is the point. The same repair is an inconvenience on one variant and a reason to scrap the car on another. A failure costing a quarter of the vehicle's value changes the purchase decision regardless of how rare it is.
