Oil Cooler Line Guides

Oil Cooler Line: What Car Owners Need to Know

Summary

  • The oil cooler is crucial to maintaining the engine oil’s ideal lubricating temperature range. The oil cooler has a supply line, where oil passes through to cool down, and a return line, where cooled oil is streamed back to the engine.
  • Signs of a bad oil cooler line include visible crimps and bends along the line, oil leaks under the engine compartment and along the cooler lines, and smell of burning oil.             
  • To make sure that the lines will be intact and this will not disrupt the cooling process and cause a dip in the oil supply, a routine maintenance check must be done every 100,000 km or whenever the oil is changed. Engine cleaning also helps keep components under the hood in good condition.
  • The oil cooler line replacement cost ranges from around $12 to as much as $500. The price varies per brand, the type of the cooler line, and make and model.

If fuel gives power to the engine, oil keeps the engine running smoothly. It lubricates various moving parts, minimizing friction from metal-on-metal contact. In the process, engine oil also does some internal cleaning by picking up contaminants and preventing corrosion in the long run. As it circulates the engine, oil also absorbs some heat. For engine oil to flow freely around the system while doing its job as a buffer between moving parts and gears, it has to maintain a certain level of viscosity. An oil cooler helps achieve this balance as a heat exchanger.

The oil cooler can be configured along with the engine cooling system or may be designed like a small radiator that uses outside air to cool the oil that goes through coils or stacked plates. The oil cooler is best used on air-cooled engines since they run hotter, as well as on automobiles designed for tracking and on vehicles built for towing and carrying larger loads since these put more stress on the drive train. Vehicles with supercharger, turbocharger, and larger engine displacements come equipped with this device.

What is an oil cooler line?

The oil cooler is crucial to maintaining the engine oil’s ideal lubricating temperature range. The oil cooler has a supply line, where oil passes through to cool down, and a return line, where cooled oil is streamed back to the engine. These oil cooler lines are built with a rigid metal part and a flexible reinforced rubber section. Typically, the metal and rubber portions of the lines are crimped together using a metal fitting, which serves as a seal to the cooler. This design makes it safe to transport pressurized oil without leaks.

What are the symptoms of a bad oil cooling line?

Over time, both the metal and rubber sections of the oil cooler lines may succumb to wear and tear. This can be due to intense temperatures, pressures, and the harsh elements they are exposed to. Any sign of damage on the lines should not be ignored to prevent costly repairs from broken-down engine components. If you notice any of these symptoms, a replacement or repair may be underway:

Visible crimps or bends in the line

Crimped or bent portions of oil cooler lines can disrupt the free flow of engine oil. This will make it hard for the oil to go in and out of the cooler.

Oil leaks under the engine compartment

A puddle of oil on the ground, particularly underneath the vehicle, indicates a leak. This may be coming from a cracked oil cooler line.

Traces of oil around the lines

Pressurized oil that is transported back and forth through the lines should be contained within. If the lines are somehow coated with oil or there are visible traces of this fluid, it is highly likely that the lines have small holes in them.

Burning smell

A leaking oil on the exhaust will produce a burning smell. With holes in the lines, oil may leak and find their way in places they should not be.

Flashing warning light

An indicator light on your vehicle will come on due to a significant drop in oil level. Low oil level can be blamed on leaks coming from a busted line.

Oil cooler leaks may come from multiple sources. They are not just isolated to the return and supply lines, so it is best to do a more thorough inspection to figure out the real source. Even with minor leaks, make sure that the engine oil level is monitored. Usually, bad oil cooler lines need to be replaced, and not repaired.

How can you maintain the good condition of the oil cooling line?

The metal parts of the oil cooling line may corrode, and the rubber portions may become brittle over time. The compression fittings may wear out as well. When threads get stripped, the lines may come loose or get disconnected, causing a leak. To make sure that the lines will be intact and this will not disrupt the cooling process and cause a dip in the oil supply, a routine maintenance check must be done. The checkup may be done every 100,000 km or whenever the oil is changed. Engine cleaning also helps keep components under the hood in good condition.

Proper maintenance and regular inspections can go a long way in preventing extensive damage to engine parts and costly replacements and repairs.

What to consider when looking for an oil cooler line replacement?

When replacing old oil cooler lines, this is usually best done in pairs, with both the outlet and inlet hoses or the return and supply lines. If one of the lines is already cracked, bent, or brittle, it is possible the other line is on the same level of wear. It is only a matter of time before you have to replace it as well. While it is highly advised that you buy a complete assembly, still, you have the option to buy a single piece depending on your needs, preference, and budget.

To be sure that the new lines can be fitted easily into the oil cooler, you have to be more specific with what you are looking for. Focus on options that are tailored to your vehicle’s year, make, and model. For instance, do not just limit your search to a Chevy oil cooler line. Key in the complete vehicle specifications to get accurate results.

It also does not hurt to check out the reviews, get more information about the manufacturer, and see if there is a warranty that goes along with your purchase.

How much is a replacement for an oil cooling line?

The oil cooler line replacement cost ranges from around $12 to as much as $500. The price varies per brand and the type of the cooler line, whether it is a single outlet/inlet line or a complete assembly. The wide price range also has to do with the vehicle’s make and model. Oil cooler lines for newer vehicle models and for performance vehicles are typically more expensive.

How to Select the Perfect Oil Cooler Line for Your Car

When driving on the road, one of the worst things that could happen to your car is to have a leak. Whichever component starts to leak, be it a leak in the radiator hose or the oil cooler hose, it's definitely going to affect the performance of your vehicle. So when you're off to purchase a replacement oil cooler line, make sure that you get only the best quality there is.

Aside from quality, you also need to consider these criteria when buying a new cooler line:

The length and angle

Before you decide to get rid of your busted oil cooler line, make sure that you take note of its specifications first. This way, you won't have a hard time looking for the right size of cooler line for your car.

The first thing you need to measure is the old cooler line's length and angle. Since you can't possibly install a wrong size cooler line in your car, you must get only the hose that fits best and will not require major modifications. Remember that the correct hose length prevents the component from going around the engine, making it vulnerable to premature wear and tear.

The cooler line's diameter

Another important thing to consider is the diameter of the oil cooler lines. It's essential to get the accurate specs of your previous cooler line, so that you won't encounter any problems installing it. Fitting a cooler hose that's too small may rupture the hose due to excessive pressure from the pumped oil. But if it's too large, oil may not flow properly as a result of insufficient pressure.

The type of cooler hose

Knowing which type of oil cooler line got damaged saves you time and effort in scanning the replacement parts available in the market. You need to know that there are two basic types of oil cooler hoses, either for the transmission or for the engine.

Transmission oil cooler hoses usually measure about five to six inches long, and are mostly situated along the passenger side of the vehicle. It contains red fluid that helps indicate leaks.

Engine oil cooler hoses, on the other hand, contain brown or black fluid and can be found along the driver's side. These are usually four to five inches long.

Installing a Replacement Oil Cooler Line

In order to keep your car in good operating condition, you need to make sure that all of its components are in good shape. Over time, some of these car parts may get worn out or damaged. When you are faced with such a situation, the best thing to do it to replace the faulty component. To install a new oil cooler line in your car, all you have to do is to follow these simple steps:

Difficulty level: Moderate

Things to prepare:

  • Collection pan
  • Funnel
  • Metric socket set
  • Metric wrench set
  • Flare nut wrench
  • Transmission fluid
  • Replacement oil cooler line
  • Jack and jack stands

Step 1: Let the engine cool down first if you have just used your car. The engine and other related components may be too hot, so wait around 30 minutes before you touch these parts.

Step 2: After the engine has cooled down, grab the jack and lift the vehicle, using jack stands to support the front part of your car. Raise it high enough to get adequate clearance when working underneath your vehicle.

Step 3: Once raised, get under your car and find the transmission drain pan. It's a huge metal tank usually found at the center of the engine. When you've located the component, place your collection pan right beneath the drain pan to minimize spills.

Step 4: Uninstall the transmission drain pan by removing the bolts with a socket wrench. Once the bolts are taken out, transmission fluid will start to flow out. Just let it drain into the collection pan until all of the fluid had been drained. Then, install a new bolt or return the bolts you've just removed.

Step 5: Look for the damaged cooler hose and remove the nuts that secure it in place. Once the nuts are loose, take out the cooler line from its attachment. Clean the attachment using rags before installing the new cooler hose. Then, install the new cooler line and make sure you tighten all the mounting bolts.

Step 6: Lower your vehicle from the jack stands and pop up the hood. Pour in the right amount of transmission fluid into the car, and check the new hose for leaks before going out for a ride.
