Citroen C4 Picasso/Grand Picasso Head gasket replacement
Why do I need to replace my Citroen C4 Picasso/Grand Picasso head gasket?
The head gasket on your Citroen C4 Picasso/Grand Picasso provides the seal between the cylinder head and engine block, which allows the engine to build up the correct amount of compression, while also allowing coolant and oil to flow through to the top of the engine.
If the head gasket fails, or ‘blows out’ the coolant and oil can mix, as well as allowing coolant to enter the combustion chamber – all bad things for the health of your Citroen C4 Picasso/Grand Picasso, especially if you keep driving!
The average price of a head gasket replacement starts around $1200 and can increase to $3000+ depending on any other damage and other work required.
Signs of a blown head gasket can be a noticeable coolant leak, reduced coolant levels, engine overheating, white smoke from the exhaust, bubbles in the coolant reservoir and discoloured oil.
If you suspect a blown head gasket the best advice is to switch the Citroen C4 Picasso/Grand Picasso off, do not drive it and book a head gasket inspection with a mechanic. Otherwise, you could cause irreversible damage to the engine.
