Oil and Filter Change

This is the most fundamental aspect of any engine’s health. Clean oil lubricates, cools, and cleans vital engine parts.

Gather Your Tools: You’ll need a drain pan, a wrench for the drain plug (typically 17mm or 19mm), an oil filter wrench, a funnel, and safety glasses.
Choose the Right Oil: Consult your owner’s manual for the recommended oil weight (often 5W-30 or 10W-30) and ensure it’s API certified. High-quality synthetic or synthetic blend is always a good choice for these high-revving engines.
Warm Up the Engine: Drive for 5-10 minutes to get the oil warm and flowing, then park on a level surface.
Drain the Old Oil: Place the drain pan under the oil pan. Remove the drain plug and let the oil completely drain.
Replace the Filter: Remove the old oil filter. Apply a thin film of new oil to the rubber gasket of the new filter before screwing it on hand-tight, then an additional 1/4 to 1/2 turn with the wrench.
Refill with New Oil: Replace the drain plug (with a new crush washer!). Pour in the recommended amount of new oil (check your manual, usually around 4.0-4.5 quarts).
Check the Level: Start the engine, let it run for a minute, then shut it off. Wait a few minutes for the oil to settle, then check the dipstick. Top off if necessary.

Pro Tip: Always use a new crush washer with your drain plug to prevent leaks. Dispose of used oil responsibly at an auto parts store or recycling center.

Coolant Flush and Replacement

Your B17 runs hot, and a healthy cooling system is paramount to prevent overheating.

Safety First: Ensure the engine is completely cool before starting. Never open a hot radiator cap.
Drain the System: Place a drain pan under the radiator drain plug (petcock). Open the petcock and the radiator cap to allow the coolant to drain. Many B-series engines also have an engine block drain plug.
Flush (Optional but Recommended): Once drained, close the petcock. Fill the system with distilled water, run the engine with the heater on high until warm, then drain again. Repeat until the water runs clear.
Refill with Coolant: Close the petcock. Fill the radiator with a 50/50 mix of Honda-approved coolant and distilled water. Fill the overflow reservoir to the MAX line.
Bleed the System: Start the engine with the radiator cap off. Squeeze the upper and lower radiator hoses to help dislodge air bubbles. Run the engine with the heater on high until it reaches operating temperature and the thermostat opens. Top off coolant as needed. Some B-series engines have a bleeder screw near the thermostat housing; open this until a steady stream of coolant emerges.

Pro Tip: Only use Honda Type 2 coolant or an equivalent silicate-free, phosphate-free, and borate-free coolant. Mixing coolant types can cause corrosion.

Spark Plugs

Fresh spark plugs ensure efficient combustion and optimal engine performance.

Access: Remove the spark plug wires (or coil packs) carefully, labeling them to ensure correct reinstallation.
Remove Old Plugs: Use a spark plug socket and ratchet to remove the old plugs. Inspect them for signs of wear, oil fouling, or rich/lean conditions.
Install New Plugs: Gap new plugs according to your B17’s specifications (usually found on an under-hood sticker or in your manual). Apply a small amount of anti-seize compound to the threads. Hand-tighten the new plugs, then use a torque wrench to tighten to spec.
Reconnect: Reattach the spark plug wires/coil packs firmly.

Air Filter and Fuel Filter

Clean filters are crucial for proper air-fuel mixture and engine health.

Air Filter: Simply open the airbox, remove the old filter, and drop in a new one. This is usually a 5-minute job. Replace every 15,000-30,000 miles or more frequently in dusty conditions.
Fuel Filter: The B17’s fuel filter is typically located in the engine bay, on the firewall. This can be a bit messy due to residual fuel pressure.
1. Depressurize: Consult your manual on how to safely depressurize the fuel system (often by pulling the fuel pump fuse and running the engine until it stalls).
2. Remove: Have rags ready. Use line wrenches to carefully loosen the fuel lines from the filter.
3. Install: Install the new filter, paying attention to the flow arrow. Reconnect lines, replace the fuse, and check for leaks.

Pro Tip: Always have a fire extinguisher handy when working with fuel components.

Valve Adjustment

A properly adjusted valve train is key to your B17’s VTEC operation and overall performance. This is a more advanced task, but definitely DIY-able.

Engine Cool: Ensure the engine is completely cold.
Remove Valve Cover: Unbolt and remove the valve cover.
Find TDC: Rotate the crankshaft to bring each cylinder to Top Dead Center (TDC) on its compression stroke. You’ll need a 17mm socket on the crank pulley.
Measure Clearance: Use a feeler gauge to measure the clearance between the rocker arm and the cam lobe. Compare to factory specifications (intake and exhaust clearances are usually different).
Adjust: Loosen the lock nut on the rocker arm adjuster screw, turn the screw to achieve the correct clearance, then hold the screw and tighten the lock nut. Re-check the clearance.
Repeat: Do this for all valves, cycling through the cylinders.
Reassemble: Replace the valve cover gasket (always use a new one!) and reinstall the valve cover.

Pro Tip: Precision is key here. If you’re unsure, watch a few videos or consider having a professional perform this critical honda b17 service.

Belts and Hoses Inspection

Simple visual inspections can prevent costly failures.

Serpentine Belt: Check for cracks, fraying, or glazing. If it looks worn, replace it.
Timing Belt: This is a critical item. Honda recommends replacement every 60,000-90,000 miles. If it breaks, your engine will suffer catastrophic damage. This is a complex job often best left to a professional, but at least be aware of its service interval.
Hoses: Inspect radiator hoses, heater hoses, and vacuum lines for cracks, bulges, or softness. Replace any suspicious ones.

Brake System Check

Safety is paramount. Regular brake inspections are non-negotiable.

Pads and Rotors: Check pad thickness and rotor condition (no deep grooves or excessive rust).
Brake Fluid: Check the level and color. If it’s dark or murky, it’s time for a flush. Brake fluid is hygroscopic (absorbs moisture), which reduces its boiling point and can cause corrosion.
Brake Lines: Inspect for leaks, corrosion, or damage.

Transmission Fluid

For both manual and automatic B17s, clean transmission fluid is vital for smooth shifts and longevity.

Manual Transmission: Drain and refill with Honda MTF (Manual Transmission Fluid) or an equivalent GL-4 rated fluid. Check your manual for the exact specifications and capacity.
Automatic Transmission: Perform a drain and fill (not a flush, which can be detrimental to older transmissions). Use only Honda ATF-Z1 or DW-1. Repeat this process 2-3 times over a few hundred miles to replace most of the old fluid without shocking the system.

Tackling Common Problems: Honda B17 Service & Troubleshooting

Even with diligent maintenance, issues can arise. Knowing the common problems with honda b17 service can help you diagnose and address them quickly.

Oil Leaks

The B-series engines are notorious for a few oil leak spots.

Valve Cover Gasket: Often the easiest to spot and fix. Replace the gasket and the spark plug tube seals.
Distributor O-Ring: A common culprit. The O-ring hardens over time, leading to leaks down the back of the engine. A simple and inexpensive fix.
VTEC Solenoid Gasket: Another common leak point. Replace the upper and lower gaskets (and the screen if it’s clogged).
Oil Pan Gasket: Less common but can happen. Requires draining the oil and dropping the pan.

Pro Tip: Clean the engine thoroughly, then drive it for a bit. Use a flashlight to pinpoint the exact source of the leak, making diagnosis much easier.

VTEC Issues

If your B17 isn’t hitting VTEC, or you’re experiencing a loss of power at high RPMs, here’s what to check:

Faulty VTEC Solenoid or Pressure Switch: These electrical components can fail. Test them with a multimeter or replace if suspected.
CEL Codes: Check for “Check Engine Light” codes. P1259 (VTEC System Malfunction) is common.

Idling Problems

Rough idle, fluctuating RPMs, or stalling can be frustrating.

IACV (Idle Air Control Valve): Often gets dirty and sticky. Remove and clean with throttle body cleaner.
MAP Sensor: A dirty or faulty Manifold Absolute Pressure sensor can cause issues. Clean or replace.
Vacuum Leaks: Inspect all vacuum lines for cracks or disconnections.
Throttle Body: A dirty throttle body can impede smooth airflow. Clean it thoroughly.

Overheating

If your B17 is running hot, address it immediately to prevent severe engine damage.

Low Coolant: Check the level in the radiator and overflow reservoir.
Faulty Thermostat: A stuck closed thermostat prevents coolant circulation. Test by placing in hot water and observing if it opens.
Clogged Radiator: External debris or internal corrosion can reduce cooling efficiency.
Bad Water Pump: If you hear grinding noises or see leaks from the pump, it’s failing.
Radiator Fan: Ensure the fan turns on when the engine gets hot or when the A/C is engaged. Check the fan motor, relay, and fuse.
