The Honda F23 series engine is a 2.3 liter, all-aluminum block, 16-valve, solitary overhead camshaft (SOHC) motor offered in the Honda Accord (1994–2002) and Acura CL (2.3L). Time belt failure may result in one of two people the entry or exhaust valves bending after contacting the pistons. If the belt has actually broken, a compression leakage check is recommend to determine if the valves need replacement. Compression leakage from any type of of the cylinders (indicating bending valves) will need the remove of the cylinder head. If compression leakage is present, inspection and rebuild the the head by a reliable automotive machine shop is encourage in lieu of doing-it-yourself. This article only covers timing belt and also water pump replacement.

The belt instead of interval is one of two people 90,000 or 105,000 miles based on the particular model year. Examine the owner's manual for the particular service interval. If the mileage is listed below the threshold but the car is end 7 year old, consider performing a replacement together preventative maintain (PM). Timing belts can not be visually inspected for wear. Moreover, a visual inspection would call for the removal of the time belt cover i m sorry is time far better spent working on the replacement.

Gates is an original equipment manufacturer (OEM) supplier for Honda; other OEMs incorporate Aisin, Dayco, and also Continental. No premature birth belt fail or difficulties have to be encountered with any type of of this brand suppliers, therefore replacement with initial Honda components is not necessary.

The Cooling System

If the cooling system appears murky or has been changed with anything various other than Honda coolant, consider replacing the water pump. Coolant replenishment/replacement with non-Honda coolant include borates and silicates will deteriorate the pump's rubber seals and also aluminum, and also the pump will eventually fail. If the cooling system includes original Honda coolant, a simple drain-and-fill with brand-new Honda coolant is adequate.

The Valve sheathe Gasket

The valve cover have to be gotten rid of or elevated to eliminate the top timing belt cover. A brand-new valve sheathe gasket is highly recommended to avoid future gasket leaks. If the gasket hasn't ever been replaced, making use of the present gasket with the valve cover bolt grommets and the spark plug tube seals will result in oil seepage or leaks. Applying RTV sealant to the old gasket does not job-related to avoid or protect against oil leaks native the valve sheathe gasket.

Special Tools

Since the F23 engine rotates counter-clockwise and also in the lack of an affect driver that generates end 150 lbs the torque, a Honda crankshaft wheel holder tool need to be used to store the sheave from relocating when attempting to relieve tension on the crankshaft pulley bolt. However, the sheave bolt might possibly be eliminated with a hand-operated transmission Honda by keeping the vehicle in gear with the wheels on the ground and the parking brakes on.


Honda, Toyota, and Nissan carry out not make their very own replacement parts. Castle subcontract the manufacture of original and also replacement parts and also stamp their surname on it. If belt longevity is of concern, just purchase a high saturation nitrile (HSN) belt in ~ a belt ingredient kit. To avoid a repeat belt replacement job due to a belt tensioner pulley-block bearing failure, change the bearings v the new belts.

Remove the Crankshaft pulley Bolt

Support the engine v a jack. Usage a wood plank to prevent damage to the oil pan. Check out photos below.Remove the crankshaft pulley-block bolt with a breaker bar attached to a long extension to clean the fender. The extension must be sustained to counter the force needed to gotten rid of the bolt (usually one's body weight through momentum).
