As a car owner, you want your vehicle to perform at its best and last for many years. But often, engine components like the cylinder head can start showing signs of wear and tear. From my years at Moreleta Service Centre, I’ve seen how minor cylinder head issues can turn into costly repairs if left unattended. Many of our customers ask, “Is there anything I can do to prevent cylinder head problems?” The good news is that with a few simple maintenance tips, you can help prolong the life of your cylinder head and keep your engine running smoothly.
Preventing cylinder head problems doesn’t always require you to be an expert mechanic. While major repairs are best left to professionals like us, some basic steps can be taken to keep your cylinder head in good shape. Let’s explore a few DIY tips that every car owner can use to avoid cylinder head issues and maintain their engine’s performance.
1. Keep Your Engine Cool: Regularly Check the Cooling System
The cylinder head is directly exposed to the intense heat generated by the engine. One of the most common causes of cylinder head damage is overheating. A simple yet effective way to maintain your cylinder head is to ensure that your car’s cooling system is in top condition.
Check the coolant level regularly and ensure there are no leaks in the system. Low coolant levels indicate a leak in the cooling system and can cause the engine to overheat, which puts additional stress on the cylinder head. Make it a habit to inspect your radiator, expansion bottle, thermostat, water pump and hoses for signs of wear or leaks.
If you notice any issues, bring your vehicle to us at Moreleta Service Centre so we can inspect and fix the problem before it leads to serious damage.
Pro Tip: Regularly test your coolant concentration and flush your radiator either as per the vehicle manufacturer. Remove debris and ensure proper cooling.
2. Perform Regular Oil Changes
Engine oil plays a crucial role in lubricating your engine and keeping the cylinder head functioning smoothly. Old, dirty oil loses its ability to protect engine components from friction and heat. This can cause unnecessary wear on the cylinder head and other engine parts.
At Moreleta Service Centre, we recommend checking your oil level regularly and changing it every 10,000 – 15000 kilometres or as specified by the vehicle manufacturer. If you drive in harsh conditions, such as stop-and-go traffic or dusty environments, you might need more frequent oil changes. By staying on top of your oil changes, you ensure that the cylinder head and its surrounding components are well-lubricated, reducing the chances of premature wear and tear. Using the correct grade of oil plays a crucial role in ensuring longevity.
Pro Tip: Don’t forget to change your oil filter when you change your oil. A clean good quality oil filter keeps particulates from clogging your engine and ensures the oil can do its job.
3. Watch for Warning Signs
Sometimes, cylinder head problems give you early warnings, and paying attention to these signs can help you catch issues before they get worse. Keep an eye out for the following:
- White smoke from the exhaust: This can indicate a cracked cylinder head or defective head gasket, allowing coolant to enter the combustion chamber and being expelled from the exhaust.
- Engine misfires: If your engine is not running smoothly, it may be due to cylinder head issues affecting combustion.
- Overheating: If your car frequently overheats, the cylinder head may be compromised.
- Coolant leak: Coolant can leak from various components in your cars cooling system i.e. radiator, hoses, water pump or thermostat housing. Depending on where it is leaking, the coolant could fall onto the hot engine components which causes it to evaporate and produce a sweet, warm smell which can easily be recognized
If you notice any of these signs, don’t wait. Get your car checked by professionals as soon as possible. Early intervention can save you from more expensive repairs down the road. At Moreleta Service Centre, we have the expertise to diagnose and fix any cylinder head issues before they cause more damage.
4. Maintain Proper Torque on Cylinder Head Bolts
Cylinder head bolts need to be tightened to a specific torque to ensure the cylinder head seals properly with the engine block. Over time, these bolts can loosen, leading to issues such as a blown head gasket. While you don’t need to check the torque regularly, any time your cylinder head is serviced, it’s important to ensure that the correct bolts are used and that the bolts are tightened to the manufacturer’s specifications.
At Moreleta Service Centre, we have the tools and expertise to ensure accuracy when tightening a cylinder head. This simple step can prevent major issues down the line.
5. Keep an Eye on Engine Coolant Mixture
The coolant is a special type of fluid consisting of glycol that is mixed with water which circulates through the engine and keeps it at a proper temperature in your engine. The correct balance between these two is critical for maintaining the engine temperature and preventing overheating. An improper coolant mixture can cause the engine to overheat, which puts unnecessary stress on the cylinder head. The mixing various types of coolants of can have catastrophically consequences on you engine.
It’s a good idea to test your coolant mixture periodically and ensure it’s within the recommended range. If you’re unsure how to do this, we at Moreleta Service Centre can assist. We’ll test the coolant, top it off if necessary, and ensure the mixture is appropriate for the conditions in which you drive.
Pro Tip: Use only the coolant type recommended by your vehicle’s manufacturer to prevent any damage to your engine and cooling system.
