Seal the joint between the cylinder head and the engine block with the APEX Automobile Parts Inc Cylinder Head Gasket AHG436, a Mazda Protege cylinder head gasket that is a direct-fit replacement for the 1999-2001 model years with the L4-1.6L engine.
An engine cylinder head gasket is clamped between the head and the block. It is designed to seal combustion pressure inside the cylinders and to keep coolant and oil within their own passages as they cross that joint. Signs this part may need replacing include coolant loss with no visible external leak, white smoke from the exhaust, overheating, coolant mixing with the oil, or low compression on one or more cylinders. These symptoms can have other causes, so diagnose the engine before you replace the gasket. If a failed head gasket is the cause, this APEX gasket replaces it.
When installing, follow the vehicle service information for surface preparation, the tightening sequence, and torque values. Consult that same information for the correct head fasteners and whether the originals may be reused.
Which vehicle does APEX AHG436 fit?
It fits the 1999-2001 Mazda Protege with the L4-1.6L engine.
How many head gaskets does the L4-1.6L Mazda Protege use?
It uses one. The quantity per application is 1 for the listed 1999-2001 Mazda Protege with the L4-1.6L engine.
What are the signs a head gasket may need replacing?
Common signs include coolant loss with no visible leak, white exhaust smoke, overheating, coolant in the oil, or low compression. Other faults can cause these too, so diagnose the engine first.
Can I reuse my old cylinder head bolts?
Many head bolts are torque-to-yield and single-use. Consult the vehicle service information for the correct fasteners and whether the originals may be reused.
Will replacing the head gasket fix overheating?
If a failed head gasket is causing the overheating, replacing it addresses that failure. A thermostat, radiator, or water pump can also cause overheating, so diagnose the cause before you replace parts.
