What is the torque on the head bolts on a 22re?
The torque on the head bolts of a 22RE engine is a crucial factor in ensuring the proper functioning and longevity of the engine. This article will provide a detailed explanation of the torque requirements for the 22RE engine head bolts, following a journalistic style with proper HTML formatting.
Torque Specifications for 22RE Head Bolts
The recommended torque for the head bolts on a 22RE engine is 45-50 ft-lbs (61-68 Nm). This torque specification is essential to maintain the proper seal between the cylinder head and the engine block, preventing any leaks or potential engine damage.
Importance of Proper Torque
Ensuring the head bolts are tightened to the correct torque is crucial for several reasons:
- Seal Integrity: Proper torque ensures a tight seal between the cylinder head and engine block, preventing oil or coolant leaks that could lead to engine damage.li>
- Structural Integrity: Correctly tightened head bolts maintain the structural integrity of the engine, preventing the cylinder head from warping or becoming misaligned.
- Optimal Performance: Proper torque allows for efficient combustion and heat transfer, contributing to the engine's overall performance and longevity.li>
Failure to maintain the recommended torque on the 22RE head bolts can result in various issues, such as oil or coolant leaks, engine misfiring, and even complete engine failure.
Torque Sequence and Procedure
When tightening the head bolts on a 22RE engine, it is essential to follow a specific torque sequence and procedure to ensure even distribution of the clamping force. The recommended steps are as follows:
- Lubricate the threads of the head bolts with a high-quality engine oil or bolt lubricant.li>
- Tighten the head bolts in a specific sequence, typically starting from the center and working outwards in a star or crisscross pattern.
- Tighten the head bolts in multiple passes, gradually increasing the torque to the recommended specification.
- Recheck the torque on all head bolts after the initial tightening to ensure they are all within the specified range.
Following this torque sequence and procedure is essential to ensure even clamping force and prevent any potential issues with the 22RE engine.

How much torque does a 22re have?
The first fuel injected 22R-E engines appeared in August 1982. Output of these engines is commonly rated at 78 kW (105 hp; 106 PS) at 4,800 rpm and 185 N⋅m (136 lb⋅ft) at 2,800 rpm. In 1985, the engine was significantly reworked, output was up to 84 kW (113 hp; 114 PS) at 4,800 rpm and 190 N⋅m (140 lb⋅ft) at 3,600 rpm.

Should you torque head bolts?
The fasteners holding your heads in place should stay tight based on the right torque value, not on gobs of thread locker.
What are the torque specs for head bolts?
1> Small Engines (e.g., motorcycles, small cars): Typically, the torque for cylinder head bolts might range from about 60 to 100 foot-pounds (ft-lbs) or 80 to 135 Newton-meters (Nm).
Should I re torque my head bolts?
Do You Need To Retorque Head Bolts After Break In? Should I retorque head bolts? Yep, that seems to be a big question on the web and it gets, like most questions on the internet, a variety of answers. In short, at least here in 2020, the answer is no, you don't have to retorque head fasteners, maybe.
