Troubleshooting Common Problems with Changing a Honda Accord Timing Belt
Even with a detailed guide, DIY projects can throw curveballs. Here are some common problems with change timing belt Honda Accord and how to overcome them.
Stuck Crankshaft Pulley Bolt
This is arguably the most common and frustrating hurdle. The crank bolt can be incredibly tight, often factory-torqued to over 180 ft-lbs and sometimes sealed with Loctite.
- Solution: Use the specialized Honda crankshaft pulley holder tool. A long breaker bar (3-4 feet) or a cheater pipe over your breaker bar is often necessary. A good impact gun (1000+ ft-lbs) can also work wonders, but be careful not to damage the bolt head. Heat from a propane torch can sometimes help break the Loctite bond, but use extreme caution around fuel lines and plastic components.
Timing Marks Don’t Align After Two Revolutions
This means your timing belt is off by a tooth or more. Do not start the engine!
- Solution: You must re-do the timing belt installation process from the point of installing the new belt. Relieve tension, remove the belt, re-align the sprockets to TDC, and then reinstall the belt, being extra careful to maintain tension and ensure all marks align.
Engine Won’t Start or Runs Rough After Installation
If the engine cranks but doesn’t start, or starts and runs very poorly, the timing is likely off.
- Solution: Immediately shut off the engine. Do not attempt to drive it. Re-check all timing marks following the steps above. If you suspect valve damage, a compression test can confirm if valves are bent. At this point, it’s often best to consult a professional mechanic.
Leaking Seals After Replacement
If you replaced camshaft or crankshaft seals, and they’re leaking, it means they weren’t installed correctly or were damaged during installation.
- Solution: You’ll need to partially disassemble the engine again to replace the faulty seal. Ensure the new seal is installed flush and evenly, using a seal driver or a socket of appropriate size. Always lubricate the seal lip before installation.
