How to properly maintain your Cadillac CT4 engine

If you want your Cadillac CT4 to serve you for many years and not cause you problems, you need to treat it responsibly - to monitor and maintain in excellent condition. The engine, as the most complex part of your Cadillac CT4, requires the most attention. Even small malfunctions can lead to bigger problems over time, which can lead to costly repairs or even the need to replace the entire engine.

We've prepared a list of things you need to do to keep your Cadillac CT4 engine running for a long time and not cause you headaches.

Oil Changes: Most cars require an oil change every 5,000 to 7,500 miles, or every 6 months to a year.
Oil filter: Change the oil filter every time you change the oil in your vehicle.
Timing Belt: Timing belts should generally be replaced every 60,000 to 100,000 miles or every 5 to 7 years, whichever comes first. It's important to follow the manufacturer's recommendations for timing belt replacement, as failure to replace the timing belt in time can result in serious engine damage.
Timing Chain:Timing chains generally last longer than timing belts and do not require replacement at regular intervals. However, they do require regular inspection as part of routine maintenance to ensure that they are operating properly and not excessively worn. If a timing chain shows signs of wear or damage, it should be replaced promptly to avoid engine damage.
Air Filters: The engine air filter should be changed every 15,000 to 30,000 miles, or every 2 years. The cabin air filter should be changed every 15,000 to 25,000 miles, or every year.
Fuel filter: Change your fuel filter every 30,000 to 50,000 miles or every 2 to 3 years, whichever comes first.
Coolant: A general guideline is to replace the coolant every 30,000 to 50,000 miles or every 2 to 5 years, whichever comes first.
Battery: The battery should be inspected every 6 months and replaced every 3 to 5 years.
Belts and Hoses: Hoses and belts (e.g alternator belt or power steering belt, not to be confused with a timing belt) should be inspected every 25,000 miles and replaced if they show signs of wear or cracking.
Spark Plugs: Spark plugs should be replaced every 30,000 to 100,000 miles, depending on the type of plugs and the make and model of the car.
Neglecting regular maintenance and skipping care for your car can lead to reduced performance, increased repair costs, safety risks, decreased resale value, and engine damage. To avoid these issues, it's important to follow the manufacturer's recommended maintenance schedule and address any issues promptly to ensure that your car is running at its best.
