5 known faults tagged with Head Gasket
2.2 D-CAT Head Gasket and Carbon Blockage
CriticalThe 2.2 D-CAT (Diesel Clean Advanced Technology) engine is perhaps Toyota's least reliable engine. It suffers from massive carbon buildup, 5th injector failure, and head gasket blow-outs.
Coolant Loss from Integrated Exhaust Manifold
SevereThe 1.0 EcoBoost's unique integrated exhaust manifold/cylinder head design causes head gasket stress. Coolant loss without visible leaks is a known issue on higher-mileage Focus Mk3 examples.
Coolant Loss and Head Gasket Failure
SevereThe Corsa E 1.4 turbo shares the head gasket vulnerability of its predecessors. Coolant loss without visible external leaks is a red flag that demands immediate investigation.
Coolant Loss from Cylinder Head
SevereThe 1.0 EcoBoost has an integrated exhaust manifold cast into the cylinder head. This design causes head gasket stress and coolant loss, sometimes causing overheating.
Coolant Loss and Head Gasket Failure
SevereThe Z12XE and Z12XEP 1.2-litre petrol engine in the Corsa D is known for coolant loss. In many cases this escalates to head gasket failure if not caught early.
