Should you Replace your Subaru's Head Gasket?

Before we answer that question, it's important to understand what a head gasket does. It is compressed between the engine block and the car's cylinder head. It's designed to seal in the interior combustion process and keep engine coolant and oil from mixing together.

Anytime your car's service light comes on, you should take it into a certified Subaru service department to see what's wrong. Some common causes for head gasket failure include the engine overheating, engine pre-ignition, and detonation.

Delaware Subaru Head Gasket Repair

Since it is tricky to get to, a head gasket repair could take up to two full days, but we need ample time to repair, recheck everything, and make sure your car is again ready for the road. Ask your service advisor about our car loaner problem, so you won't be stuck in a bind.

Besides replacing the head gasket, the repair also includes valve cover gasket and thermostat/gasket replacements and an oil and filter change.

We typically recommend switching out the timing belt, timing idlers, tensioner, cam and crank seal as well. If you aren't sure if your water pump has been replaced, we can check and replace that, too.

Depending on your car's year and engine configuration, the base head gasket job for parts, which includes tax and labor, could run a pretty penny between $1,500 and $1,600. Adding additional parts like the timing belt, idlers, and tensioner adds about $400. The average total cost for an automatic transmission vehicle could run you between $2,100 and $2,300. A Subaru with a manual transmission including a clutch runs $2,400-$2,600.
