Honda Civic IV (1988–1991) – Timing System & Drive Belts

The timing system in the Honda Civic IV (1988–1991) is responsible for synchronizing the crankshaft and camshaft with absolute precision. Most engines from this generation – including D13, D14, D15, D16 and the iconic B16A1 – use a timing belt. These are interference engines, meaning that a failed belt can result in serious valve damage. For that reason, the condition of the timing belt, tensioner rollers, tension springs, water pump and accessory drive belts is critical to long-term reliability.

This category includes all essential timing components for the Honda Civic IV, sourced from trusted manufacturers: Honda OEM, Gates, Koyo, NSK, Aisin and NPW. All parts are matched to the engines commonly found in this generation.

Timing Components for Honda Civic IV

Timing Belts

The timing belt transfers rotational motion from the crankshaft to the camshaft(s). Since classic Honda engines frequently operate at high RPM, the belt must offer excellent stability and resistance to stretching. Available options include:

• Honda OEM timing belts with factory specifications,
• Gates timing belts known for durability and consistent performance,
• application-specific belts for all D-series engines and the B16A1 DOHC VTEC.

Tensioner Rollers & Tension Springs

Tensioner and guide rollers maintain proper belt tension. A worn or noisy roller can lead to instability, while a seized bearing or weakened spring can cause the belt to jump a tooth or fail completely. Available options:

• Honda OEM tensioner components,
• high-quality Japanese rollers from Koyo and NSK,
• timing tension springs dedicated to D-series and B-series engines.

Water Pumps – Aisin & NPW

In many Civic IV engines, the water pump is driven directly by the timing belt. A worn or seized pump can destroy even a brand-new belt, making pump replacement strongly recommended during major timing service.

• Honda OEM water pumps,
• Aisin and NPW pumps – top-tier Japanese replacements with OEM-level reliability.

Accessory Drive Belts

Accessory belts (alternator, power steering, A/C) are critical to everyday operation. A worn belt may squeak, slip or fail unexpectedly.

• Honda OEM auxiliary belts,
• high-durability Gates belts compatible with factory tensioners.

Why Timing Maintenance Is Critical in the Civic IV

• Most engines are interference designs – belt failure can cause valve damage.
• Old rollers and springs lose tension over time, increasing risk of belt slip.
• A refreshed timing system ensures smoother engine operation and reliability.
• Preventive replacement is far cheaper than repairing a damaged cylinder head.

Recommended Manufacturers – OEM & Aftermarket

We focus on components known for long-term durability:

• Honda OEM – factory-spec belts, rollers and tensioners,
• Gates – high-quality timing belts and accessory belts,
• Koyo & NSK – Japanese tensioner bearings used as OEM in many Hondas,
• Aisin & NPW – reliable water pumps for D-series and B-series.

FAQ – Honda Civic IV Timing & Belts

How often should the timing belt be replaced?

Typically every 90,000 km or 5 years. For vehicles over 30 years old, earlier replacement is recommended.

Should the water pump be replaced together with the timing belt?

Yes. Since the pump is belt-driven, a worn pump can cause immediate belt failure.

Are timing components the same for all Civic IV engines?

No. D13, D14, D15, D16 and B16A1 engines use different belts, rollers and pumps. Using the VIN or exact engine code ensures correct compatibility.

Should the tensioner spring be replaced?

If the vehicle’s service history is unknown, replacing the spring is strongly recommended to maintain proper belt tension.
