DNJ HBK903 cylinder head bolt set for the 1987-1990 Toyota Tercel 4-cylinder 1.5L clamps the cylinder head to the engine block. This engine cylinder head bolt set is designed to keep the head gasket sealed under extreme heat and mechanical stress.
- Uniform load distribution across the cylinder head surface to help maintain gasket sealing
- Heat-treated carbon or alloy steel for strength and fatigue resistance under high pressure and thermal cycling
- Hardened steel washers for accurate torque application and consistent clamping force
- Application-specific set designed to service the whole cylinder head installation
Quick facts
- Part: DNJ HBK903 cylinder head bolt set
- Also called: engine cylinder head bolt set
- Fits: 1987-1990 Toyota Tercel 4-cylinder 1.5L
- Material: heat-treated carbon or alloy steel
- Condition: New
Coolant or oil seeping at the head joint, overheating or a head gasket that keeps failing can mean the bolts have lost clamping force. A warped cylinder head, a failed head gasket or a cooling-system fault can produce these symptoms as well, so find the cause before buying this set.
Fits
It fits the 1987-1990 Toyota Tercel 4-cylinder 1.5L (L4-1.5L), and that engine takes one set.
