Honda City Engine Cylinder Head Bolt Sets
Honda City Engine cylinder head bolt sets
Engine cylinder head bolt sets for the Honda City start at $81.95. AutoBuffy stocks 1 sets from Elring. Cylinder head bolts clamp the head gasket between the engine block and cylinder head, sealing combustion pressure and coolant passages. Stretched, corroded, or improperly torqued bolts allow the gasket to fail, leading to coolant loss, overheating, and internal engine damage.
Signs your Honda City needs new cylinder head bolts
- White or sweet-smelling smoke from the exhaust, indicating coolant burning in the combustion chamber due to a blown head gasket caused by insufficient bolt clamping force
- Milky or foamy residue on the oil dipstick or inside the oil filler cap, a sign that coolant is mixing with engine oil through a compromised head gasket seal
- Persistent overheating or a coolant level that drops without any visible external leak, pointing to combustion gases pressurizing the cooling system
- Bubbling in the coolant reservoir or radiator when the engine is running, caused by combustion gases escaping past a gasket held by weakened bolts
- Loss of compression in one or more cylinders, detectable during a compression test, resulting from combustion pressure bypassing the head gasket
- Visible rust, corrosion, or thread damage on existing head bolts discovered during a head gasket or engine rebuild, indicating the bolt set must be replaced before reassembly
Which engine cylinder head bolt set should you buy for your Honda City?
The most important decision when buying a head bolt set for your Honda City is whether to choose torque-to-yield (TTY) single-use bolts or reusable bolts, as the engine design dictates which type is correct. Beyond that, material grade and coating determine long-term clamping reliability, especially in high-heat or high-mileage applications. Always verify whether your engine uses TTY bolts before purchasing, because mixing types will compromise the seal.
OEM-Spec Torque-to-Yield (TTY) Set
Best for
Engines originally designed with TTY bolts; any rebuild where OEM specs must be met
What you get
Single-use bolts that stretch to a precise yield point for optimal gasket clamping; must be replaced every time the head is removed
Reusable High-Strength Bolt Set
Best for
Engines using conventional bolt designs; budget-conscious rebuilds with multiple teardowns expected
What you get
Grade 8 or equivalent bolts that can be removed and re-torqued without losing clamping integrity; inspected for stretch before reuse
Performance / ARP-Style Stud Kit
Best for
High-performance, forced-induction, or competition builds on the Honda City needing maximum clamping load
What you get
Chrome-moly or stainless studs with nuts for more even clamping force, easier head removal without disturbing the block, and higher clamp loads than standard bolts
Complete Head Hardware Kit
Best for
Full engine rebuilds or situations where head bolts, washers, and related fasteners are all being replaced at once
What you get
Matched set including bolts, hardened washers, and sometimes thread sealant; eliminates mismatched hardware and simplifies the rebuild process

Replacing the engine cylinder head bolt set on a Honda City
Advanced⏱ 4–8 hoursTorque wrench (capable of ft-lb and angle/degree settings)Breaker bar and socket setTorque angle gaugeThread chaser or tap set (to clean block threads)Micrometer or caliper (to measure bolt stretch on reusable types)
Replacing cylinder head bolts on a Honda City requires draining coolant, removing ancillary components, and carefully lifting the cylinder head to expose the bolt bores. Block and head sealing surfaces must be thoroughly cleaned, and block threads should be chased and blown out before installing new bolts. Bolts must be installed in the manufacturer's specified sequence with the correct multi-stage torque and angle procedure to achieve an even, leak-free seal.
Frequently asked questions
How much does it cost to replace engine cylinder head bolt sets on a Honda City?
Parts for a Honda City head bolt set start at $81.95 at AutoBuffy. Labor to remove the cylinder head, replace the bolt set, and reassemble with a new head gasket is substantial — this is an advanced repair typically totaling several hours of shop time. Doing the work yourself keeps costs close to the parts price alone.
Can I reuse the cylinder head bolts on my Honda City?
It depends on the bolt type. If your Honda City uses torque-to-yield bolts — which most modern engines do — they must be replaced every time the head is removed. TTY bolts permanently stretch during installation and will not provide correct clamping force if reused. Check your service manual to confirm the bolt type before deciding.
Do I need to replace the head gasket when I replace the head bolts on a Honda City?
Yes. Any time the cylinder head is removed on a Honda City to access or replace head bolts, the head gasket must also be replaced. A used head gasket will not re-seal reliably even if it appears undamaged. Installing a new head gasket together with the bolt set is standard practice and protects the repair from immediate repeat failure.
What happens if cylinder head bolts are not torqued correctly on a Honda City?
Incorrect torque — too low or too high — causes uneven clamping across the head gasket. Too little torque allows combustion gases and coolant to bypass the gasket. Too much torque can stretch or snap bolts and warp the cylinder head. Always follow the manufacturer's multi-stage torque sequence and angle specifications for your Honda City.
Do cylinder head bolts need thread sealant on a Honda City?
Some head bolts on the Honda City thread into blind holes and require only a light oil coating on the threads and underside of the bolt head. Others thread into water jacket passages and require anaerobic thread sealant to prevent coolant seepage. Check your service manual to identify which bolt positions on your engine need sealant before installation.
How do I know if my cylinder head bolts are stretched or damaged on a Honda City?
For reusable bolt types, measure the bolt shank length against the manufacturer's discard specification using a micrometer or caliper. Visually inspect threads for corrosion, galling, or deformation. Any bolt that is bent, corroded, or measures beyond the stretch limit must be replaced. When in doubt, replacing the full set is the safest and most cost-effective approach.
