The head gasket part by itself will cost between $50 – $100 depending on your vehicle. Now the labor to replace the head gasket is another story. This is a very labor intensive procedure to replace the head gasket and automotive mechanic knowledge is required. Your mechanic will need to remove the engine head to get to the head gasket. But, before he does this, components such as the intake and exhaust manifolds must be removed as well as some of the sensors, ignition system and valve train. This takes time and mechanics are usually paid on an hourly basis. The gasket part plus the labor to remove and install the head gasket could run around $1,000 or more. Some vehicles will be less and others will be more.
Your relationship with your mechanic could also be a factor in the total head gasket repair cost. Keep in mind the price above is to remove the old gasket and replace it with a new one assuming you haven’t sustained any internal damage to the engine block, cylinder heads, pistons or valves. If the mechanic finds internal damage you could be looking at a substantially higher price.
