Understanding the Cooling System: How to Prevent Overheating in a 2018 Range Rover

Changing the oil in your 2018 Range Rover might seem like a daunting task, but with the right tools, a bit of patience, and some attention to detail, you can handle it yourself. Not only will this save you money, but it also gives you a better understanding of your vehicle’s maintenance. Whether you’re a seasoned DIY mechanic or trying this for the first time, this guide will walk you through everything you need to know.

Before you crawl under the vehicle, make sure you’ve got the right tools and materials. The last thing you want is to drain the oil and realize you’re missing something essential.

• Socket set – A 13 mm socket and ratchet wrench for the drain plug.
• Oil filter wrench – Required to remove the old filter.
• Oil catch pan – At least a 10-quart capacity to prevent spills.
• Funnel – A good one makes refilling much easier and cleaner.
• Gloves and safety glasses – Protect your hands and eyes from hot oil.
• Shop towels or rags – Useful for cleanup.

• Oil type: Synthetic 5W-30 (Check your owner’s manual for recommended brands and approvals.)
• Oil capacity: Approximately 8.5 quarts.
• Oil filter: OEM filter or a high-quality aftermarket filter designed for the 2018 Range Rover.

Find a level surface to work on and let the engine cool for about 15-20 minutes if you’ve been driving. Warm oil drains better, but you don’t want it so hot that it burns you.

A Range Rover has considerable ground clearance, but if you need more space, use jack stands or ramps for safety. Never rely solely on a jack.

• Place the oil catch pan directly under the drain plug (located on the bottom of the oil pan).
• Use the 13 mm socket wrench to loosen and remove the bolt. Let the old oil drain completely.
• Inspect the drain plug washer. If it’s worn or damaged, replace it to prevent leaks.
• Reinstall the drain plug and tighten it firmly, but avoid over-tightening, as this can strip the threads.

• Use the oil filter wrench to remove the old filter. Have a rag ready. It’ll likely drip some oil.
• Check the rubber gasket on the old filter. It sometimes sticks to the engine. If left behind, it can cause leaks when you install the new filter.
• Apply a thin layer of new oil to the gasket on the new filter, then install it by hand. Once snug, give it another quarter to half turn. No need to overtighten.

• Insert the funnel into the oil fill cap (located on the top of the engine).
• Pour in about 8 quarts to start, then check the oil level with the dipstick.
• Start the engine and let it run for a minute or two. This allows the oil to circulate and fill the new filter.
• Shut the engine off, wait a few minutes, then recheck the oil level. Add more if needed, ensuring it’s within the correct range on the dipstick.

Look under the vehicle to ensure there are no oil drips from the drain plug or filter. If you see leaks, tighten as needed.

Take the old oil and filter to a recycling center or local auto shop that accepts used oil. Never dump it down the drain or on the ground.

Even seasoned DIYers make the occasional slip-up. Here are a few to watch out for:

• Over-tightening the drain plug or oil filter – This can strip threads or crush the rubber gasket, leading to leaks.
• Not replacing the washer on the drain plug – Some vehicles use a crush washer that must be replaced each time.
• Forgetting to check the oil level after running the engine – The filter holds oil and may require you to add more after circulation.
• Using the wrong oil – Always check the manual to ensure you’re using manufacturer-approved 5W-30 synthetic oil.
• Skipping proper disposal – Used oil is hazardous waste. Drop it off at an auto parts store or designated recycling center.

If you’re going through the effort of changing your own oil, you probably care about keeping your Range Rover engine maintenance in top shape. A few extra steps can go a long way:

• Stick to the recommended oil change intervals – Typically, this is every 7,500 to 10,000 miles, depending on your driving habits.
• Keep an eye on oil consumption – High-mileage engines may burn oil faster. Checking the level regularly helps catch issues early.
• Inspect for leaks and unusual smells – A slow leak can develop into a bigger problem if left unchecked.

Taking the time to do regular preventive maintenance yourself can extend the life of your engine, save you a trip to the shop, and keep you in tune with your vehicle’s health.
