What to know about theOil Cooler Lines:
You won’t discover oil cooler lines on all engines. They’re more prominent on supercharged and turbocharged engines, as well as on larger engines that require extra oil cooling, such as older full-sized SUVs. These lines run to an oil cooler, which works a lot like your car’s radiator, enabling air to remove excess heat before the oil is sent back into the engine. In most of these instances, the oil cooler lines will be solid metal tubes because the oil is pressurized, though some have reinforced rubber hose sections as well. If the oil cooler lines are leaking, the oil level can drop quickly, producing possible internal engine damage.
Facts to Note:
Oil cooler lines are pressurized when the engine is working, and pressure can continue in the lines even after the engine is turned off.
Leaking or clogged oil cooler lines can compromise the operation and safety of your engine.
It may be wise to change both the oil cooler lines and the fittings. Some lines are actually linked to the fittings, so replacement is mandatory.
If the lines go to an oil cooler, it may be necessary to change the oil cooler as well, particularly if the damage is due to debris buildup.
How to Fix:
The vehicle is allowed to cool. The vehicle is raised and secured on jack stands. A drain pan is positioned under the oil cooler lines.
The two oil cooler clamps and lines are disconnected and the excess oil is allowed to drain. The faulty oil cooler lines are detached from the oil filter housing and detached from the vehicle.
The new oil cooler lines are fixed to the oil filter housing and secured with new clamps. The two oil cooler lines are linked and secured with new clamps to the oil cooler.
The vehicle is started and checked for oil leaks then lowered off of the jack stands. The oil level is checked and topped off with the correct oil.
The vehicle is road tested for proper operation and the cooler lines are rechecked for any signs of leakage.
We recommend that you follow your automaker’s recommendations on oil changes and oil cooler service. There is no set lifespan for oil cooler lines, and a correctly maintained engine will never need to have them changed. Inspection by one of your expert mechanics for proper operation, obstruction or deterioration is recommended.
Common symptoms indicating you may need to changethe Oil Cooler Lines:
Leaking oil around the oil cooler line fittings
Bends, crimps or damage to the lines
Importance of this service:
Because engine oil is a vital consideration for multiple components, changing damaged, worn or clogged oil cooler lines is important. Work with our professional mechanics to ensure safety, the right parts, and a correct diagnosis of both the cause and the extent of the damage.
