To keep your engine safe, follow these steps:
First, check under the hood before driving. Make sure coolant levels are normal. Then inspect the oil cooler hose and coolant return hose for cracks, bulges, or leaks. A damaged oil cooler hose can’t properly circulate coolant, leading to overheating.
Clean your radiator and replace coolant every two years at minimum. Flush the radiator with a special cleaner to remove dirt from inner walls—this keeps coolant flowing freely through the oil cooler hose.
In summer, mix coolant and water in a 1:1 ratio. Or use pre-mixed coolant for convenience. This mixture resists boiling, protecting the oil cooler hose and other parts from heat damage.
Signs of an Oil Cooler Hose Leak
If you park and see a puddle under your car, it might be coolant from a leak. Check the oil cooler hose first—small cracks or loose connections often cause leaks here.
Don’t ignore leaks. Even a small drip from the oil cooler hose can lower coolant levels over time, leading to overheating. Head to a repair shop to fix or replace the hose right away.
Final Tip: Prioritize Oil Cooler Hose Health
Your car’s oil cooler hose plays a big role in preventing engine damage. By checking it regularly, replacing old coolant, and fixing leaks early, you’ll keep your engine running at the right temperature—no matter how hot it gets outside.
