Geo Tracker Cylinder Head Bolt

Troubleshooting Tips for Your Geo Tracker Cylinder Head Bolt

Without the small metal fasteners like your Geo Tracker's cylinder head bolts, it would be impossible for the engine to remain in place. These tiny components ensure that the large ones are secured in their position for them to work. So if you have a worn-out, rusted, or missing Geo Tracker cylinder head bolt, then expect that there would be problems in your mini SUV. These bolts are very tight, and having them loose is a rare possibility. To know whether your cylinder head bolt is in good condition, here are some troubleshooting tips that we thought that you should know:

Coolant leak

If you notice a puddle of coolant underneath your vehicle most of the time, then something must be causing it to leak. If you cannot find the source of the leak, then you should check the cylinder head bolts if they are loose. Although this is an uncommon problem, you can still check if the cylinder head bolts are tightened. But if these bolts have been removed once to give way to cylinder head gasket replacement, then it is possible that they could get loose. To retighten the bolts, you could either refer to your vehicle's manual on how much torque it needs, or you can just have it fixed by an experienced mechanic.

Engine overheating and misfiring

So you were driving and you just saw a white smoke seeping from underneath your hood. Your engine is overheating. Did you know that this could also be caused by loose or worn-out cylinder head bolts? When these bolts become loose due to age, changes in temperature, or even corrosion, they could cause your engine to have water loss, which could lead to overheating. You could also have a difficulty starting your vehicle. When this happens, inspect if all the cylinder head bolts are still in good condition and if they are still intact. They might be incorrectly torqued when they were once replaced or after a rebuilding. Replace any rusted or worn-out bolts with new ones immediately and make sure to torque them based on the correct specifications.

  • Geo Tracker Cylinder Head Bolt Maintenance Tips

    Having your Geo Tracker's cylinder head bolts loose is known to be an uncommon problem, since they are usually torqued with the right specifications to be very tight. However, due to the various factors that could affect their durability, like corrosion, age, and temperature, they eventually succumb to wear and tear after a few years. But did you know that you can at least do something to prevent this from happening? Here are some of the tricks that you can do to keep your Geo Tracker cylinder head bolts in good condition:


    Inspect them for damage.

    Typically, the cylinder head bolts are removed to give way to a head gasket replacement. After that, they should be torqued into place again to ensure that they are tight enough to withstand the pressure in the engine assembly. Hence, some of their parts could be damaged from being stretched whenever it is removed and replaced. Usually, when their threads become deformed, they are good as worn-out. Replace all worn-out bolts, but make sure that they meet the specifications listed in your vehicle's service manual.


    Clean the threads.

    Since the bolts are sealed tight into place, you can no longer clean them, unless you will remove them from the cylinder head. What you can do is to clean the threaded holes in the engine block using a bottoming tap. Remove all debris out of thread; you can use a compressor blower and a small cloth to get rid of the dirt.


    Do not lubricate.

    For any other bolts that are not torqued, you can always lubricate them to keep them from wearing out due to friction. But not for cylinder head bolts that are expected to remain tight, and when we say tight, we mean very tight. Never put any lubricant on them to avoid having problems when they became loose.


    Torque them based on specifications.

    Whenever you remove or replace the cylinder head bolts from their location, make sure that they will be torqued based on the specifications indicated in your vehicle's service manual. This is to ensure that they will not become loose anytime soon and that they will be doing their job efficiently.
