Does my 6.0L really need an upgraded or external Oil Cooler?

Posted by ID Speed Shop on 2022 Aug 17th

Does my 6.0L really need an upgraded or external Oil Cooler?

For starters, we've had an external oil cooler installed on our trucks since 2005.  We built our own by welding external lines from the stock oil cooler housing to an external hydraulic heat exchanger.  It worked very well, kept our oil temps in check, increased the life of the oil, and the truck ran so much better with cooler and consistent oil.  The reason is, the 6.0L trucks use oil pressure for more than just lubricating the moving parts.  Hydraulic pressure created from the engine oil controls the injectors (high pressure oil) and turbo VGT control (low pressure oil).  

After a lot of research, we have recommended and sold the IPR oil cooler for many years.  Fit and

finish is excellent and service your truck is so much easier.

Benefits and FAQ regarding IPR's External Oil Cooler Kit


IPR solved 2 major problems with the Ford 6.0 oil cooler failure issues. First, by removing the

internally mounted OEM oil cooler and relocating it next to the battery we were able to reduce

the amount of time/labor it would normally take to service the oil cooler. You can swap out a

brand-new oil cooler in as little as 20 minutes should you need to replace it for any reason.

Second, by mounting the OEM oil cooler externally we were able to filter the coolant 100%

before any coolant ever enters the oil cooler.


Q. What happens to the OEM oil cooler that was mounted inside the engine?


A. The OEM oil cooler is replaced by IPR's patent pending bypass manifold. The bypass

manifold is a bolt in replacement that has 3/4" passages that allow the coolant and oil to

continue its OEM design pathways and is then routed out to IPR's billet aluminum oil filter cap,

out to the oil cooler and back in to supply the high-pressure oil pump.


Q. Where is the oil filter located?


A. The oil filter is located in the factory oil filter housing just like the OEM oil filter.


Q. Where can I buy oil filter if I need to service my truck?


A. Oil filters can be purchased from our website, or you can purchase them at any NAPA auto

parts or local auto parts store. They are over the counter common filters manufactured by WIX.


Q. Do I have to remove the oil hoses off the filter cap every time I change my oil filter? Seems

like a hassle.


A. The 2 oil hoses do need to be removed to replace the oil filter, however it's a small

inconvenience, in most cases you can loosen the 2 oil hoses in less than 1 minute. It's a small

inconvenience once every oil change interval.


Q. Why do I have to purchase the IPR External Oil Cooler Kit when I can just install a coolant

filter in my truck with a OEM oil cooler mounted internally inside the engine.


A. Unfortunately the design of the OEM internally mounted oil coolers gets clogged up by

contaminants such chemical breakdown, cast iron corrosion fallout and casting sand from

engine manufacturing and the coolant supply for the OEM oil cooler is fed directly from the

engine block into the oil cooler. There is no way to intercept the coolant "before" it enters the

OEM internally mounted oil cooler. All aftermarket coolant filters only filter coolant after

contaminants have passed through your OEM oil cooler.


Q. The External Oil Cooler Kit is expensive it's out of my budget.


A. Considering a new OEM internally mounted oil cooler cost about $350-$410, intake gasket kit

$90 and labor to remove/install a new oil cooler can cost from $700-$900. The next time you

need to replace your clogged oil cooler the kit will pay for itself and more.


Q. Why do I have to purchase the IPR External Oil Cooler Kit when I can just install a coolant

filter in my truck with an OEM oil cooler mounted internally inside the engine and flush out the

coolant system?


A. Unfortunately the design of the OEM internally mounted oil coolers gets clogged up by

contaminants such chemical breakdown, cast iron corrosion fallout and casting sand from

engine manufacturing and the coolant supply for the OEM oil cooler is fed directly from the

engine block into the oil cooler. There is no way to intercept the coolant "before" it enters the

OEM internally mounted oil cooler. All aftermarket coolant filters only filter coolant after

contaminants have passed through your OEM oil cooler. In cases where an OEM oil cooler has

ruptured were coolant and oil have mixed into the coolant system it is extremely difficult to flush

out all the oil residue, unfortunately a new OEM oil cooler must be installed in order to flush out

the mess, this will lead to contamination of the brand-new oil cooler that was just installed.


Q. I see that IPR offers a High Flow or CF2 Coolant Filter, is this filter included in the kit?


A. The IPR High Flow Coolant Filter or CF2 Coolant filter is an upgraded filter you can purchase

as an upgrade option with your IPR External Oil Cooler Kit. IPR does recommend upgrading to

either coolant filters for maximum longevity.


Q. Will I have to purchase any other components to make this kit work in different climates?


A. No additional components will need to be purchased. Other aftermarket kits in the market

require you to purchase a thermostat kit that can cost up to $350 for cold climate use and a

possibility that you'll need to replace your transmission cooler due to fitment issues that you may

experience based on the build date and equipment on your truck. IPR require no additional parts

to make the oil cooler kit operate properly.


Q. What is the advantage of IPR External Oil Cooler Kit in comparison with a air cooled type kit

mounted in front of the truck?


A. There are many reasons why a water-cooled system is much more effective. We will go into

detail on this subject.


1. Air cooled oil cooler cores require a substantial amount of space in front of a vehicle for it to

work efficiently. In most cases an air-cooled oil cooler will restrict air flow to your radiator, AC

condenser and radiator. Some manufacturers recommend that their oil cooler cores be mounted

behind the AC condenser. The large, air-cooled oil cooler restricts enough air flow to the

condenser that it will diminish AC performance as well as radiator and intercooler performance

. Mounting the air cooler behind the AC condenser also requires the use of additional bracketry,

hardware, drilling, disassembling the front end of the vehicle, relocating the transmission cooler,

purchasing and relocating the power steering cooler, discharge AC, and recharge AC upon

installation which will require an additional 4-8 extra labor cost which can cost well over $1000.


2. Air cooled oil coolers require air flow (increased vehicle speed) and outside air temperature to

operate efficiently. In an extreme condition when a vehicle is towing a heavy load up a grade on

a hot day, the vehicle speed is limited due to the increased load from towing and climbing

resulting in less air flow and hotter outside air temps. The problem is exaggerated when a

heavy-duty fan clutch is installed which will cause parasitic power loss and increased load on

the engine also resulting in decreased fuel economy.


Water cooled oil coolers rely on the OEM radiator as a heat exchanger to cool the oil down. The

radiator used in the front of the vehicle is the largest heat exchanger on the vehicle which is very

efficient. IPR External Oil Cooler Kits require no additional fans or components.


3. Cold weather performance with water cooled oil cooler is also more efficient during warm up.

The same coolant used to cool the oil down in hot weather is also used to heat the engine oil up

to normal operating temperatures much more effectively and more consistently. The OEM

thermostat will remain closed to aid the coolant in reaching normal operating temps much

sooner than an air cooler. During cold climates an air cooler will constantly cool oil temps as it’s

trying to warm up. Some manufacturers would recommend a thermostat kit which can cost an

extra $350 and more plumbing/fittings and labor to install.


4. Water cooled is the future! The new Power stroke 6.7 utilizes coolant to control excessive

temps on the transmission, oil cooler and intercooler.
