is it ok to just buy the oil cooler kit (the internal heat exchanger) when replacing the oil cooler or should i buy the housing and all, cuz there is quite a bit of difference in price.

 

I didn't know you could just buy the internal heat exchanger or that's what I would have done. It's virtually impossible to clean one internally because of the extremely small passages. I personally would just buy the exchanger.

 

thats what im thinkin, cuz nothing can really go wrong with the housing right? its just the heat exchanger that gets plugged up or whatever right? ford just recently came out with this new updated kit. its the same part number except the last 2 letters are CA instead of AA

 

The "core" is all you need to replace. It is just the heat exchanger component. Ford did this to save money - theirs AND ours. it was a good move.

 

i agree. thanks alot.

 

What is the diff? I am curious.

 

The core bolts into the housing. This "assembly" makes a complete oil cooler - same as stock. It is just a way to replace only the affected part - the plugged plates of the cooler (ie the heat exchange components).

 

I meant in price.

 

Duh ..... I wondered why you asked ............ . I heard it was over $100 less, but do not know the exact amount.

 

Mark, I ain't smart but ain't stupid!!

 

I KNOW you ain't stupid! My apologies for sure!

As you know, I was not paying 100% attention (multi-tasking and Forum hopping).

 

My idea of multi-tasking is this and a beer.

 

When I studded my X I removed the oil cooler to do two things: back flush the coolant portion and replace the HPOP inlet filter screen.

I believe a lot of oil coolers are replaced when a simple back flush would suffice.

Here is what I did. I connected a garden hose to the oil cooler coolant outlet that goes to the EGR cooler. I placed the cooler over a bucket with T shirt tied to the top of the bucket. I applied full house water pressure (50 lbs) to the cooler and watched the water coming out for debris. A few very small dirt specs were captured in the T shirt and they were certainly not enough to restrict flow. Also, the water flow through the cooler was very good. There was no indication of restriction. I let the water run for about 5 minutes and there was no change in flow rate. If you suspect blockage, you may want to try some radiator cleaner solution. Dilute it per the instructions and fill the coolant side of the cooler. Let it set for the time per the directions and then back flush it again. Verify if you water flow has increased or is the same. I believe it is worth a try before you spend $400 for a new cooler.

I just saw a post for the oil cooler "core" quoted for about $200 on powerstrokeshop.com.

Also, on another forum a member named Albin has a TON of good pics of his plugged up oil cooler. It sure did not look like a simple backflush would dislodge the grit. I believe he even said he did not believe it would be effective.

Mark......that response did not take long! LOL.

I agree. But it cannot hurt to do a back flush first. If it is clogged as people say, there shoud be little to no water flow.

As I said before, if someone has a known failed oil cooler and they want to send it to me, I would be glad to take it apart or, if I have to, cut it apart, take pictures and post on the site. Send me a PM if you need my mailing address.
