What happens when engine oil cooler fails?

When an oil cooler fails, it can force all the coolant out of the engine and raise the risk of an overheated engine, which may lead to possible engine damage. If the leak is significant, you’ll notice coolant on the ground or see steam gushing out from underneath the hood.

Can an oil cooler be repaired?

The Industry Standard for repairing old, leaking oil coolers used to be epoxy applied directly to the area of the leak (although at Pacific Oil Cooler Service, Inc., we have never used epoxy to repair a leaking oil cooler – we perform all repairs using only an appropriate Inert-Gas type weld).

Can an oil cooler be clogged?

Does your 6.0L have a coolant and oil temperature spread exceeding the Ford specified 15ºF? This is typically an indicator that you have a clogged engine oil cooler and can be putting vital engine components at risk.

How long should an oil cooler last?

Without regular oil changes over the course of your vehicle’s life, the oil cooler may fail at 50,000 miles and need to be replaced. To keep your engine oil as clean and productive as possible, top mechanics recommend you change your oil anywhere from 3,000 to 3,500 miles (sometimes longer for synthetic oil).

Do I have to drain oil to replace oil cooler?

Technically, you should only need to put back the amount of oil that is lost from the filter. Oil is pumped thru the filter and OEM cooler and is higher that the oil in the pan.

What maintenance is usually performed on an oil cooler?

Air is purged from the oil cooler with water, in preparation for ultrasonic cleaning. Ultrasonic waves are only transmitted by liquid, so all of the air must be removed from the inside of the cooler. The coolers are then placed into one of two ultrasonic cleaning machines that Pacific Oil Cooler Service operates.
