new oil cooler #?

Rate this topic


Recommended Posts

Got a quicky here,working on an '04 F250 with ESP,needs head gaskets and an oil cooler.During the prior approval process it was brought to my attention that an updated oil cooler part#3C3Z-6A642-CA was to be used or the claim would not be paid...the old part# is AA,and this is the first I heard of this...

My parts manager is not happy 'bout this,says he's got a shelf full of the AA's,no CA's in stock...what's the deal?Is it a better,longer lasting,more dependable cooler,or just cheaper to make?

Was gonna post this on the parts forum,but.... Posted Image

^^ It's the heat exchanger, not a whole cooler. We're prepping several oil cooler cases at work as we speak for this latest and greatest shit-show.

I believe that if the oil cooler is faulty due to coolant and oil mixing together then you will be replacing the entire oil cooler. So your parts dept will still end up selling these coolers.

The kit is not hard to install,but make sure you look for all the replacable orings when you put the first one on or you will look down and say damn were does that oring go and have to take it back apart.Instructions say refer to shop manual for dissasembly and reassembly but shop manual says replace only as assy.HMMM?

If you are looking for instructions they are under the service tips tab when you look up the oasis for the truck. Its like 8 pages long. I did my first one this week and it went smooth. Wasn't a pain like I first thought it would. My only complaint is Ford wants you to do more work by rebuilding the oil cooler but they cut the labor times but what else is new?

I did my first one today. It is more work. The oil filter adapter and the cooler body were so filthy it took some extra scrubbin to get them clean. There was also a lot of coolant crust in the two coolant passage bores where the o-rings seal. I had to take a pick and follow up with some serious Scotch Brite rubbing. I see the potential for bad things to happen if guys get brutal in disassembling these things or don't take care in cleaning them.

 

This one was customer pay. I got more time than the TSB pays... and I needed it. Funny thing is, the EOT/ECT temperature split was still 5 degrees in the shop at full operating temperature.

This is funny. When I was at Grampy's place we were discussing how Ford changes their tune all the time about doing things. Like on 6.4 - DON'T COVER THE COOLING STACK! Well....okay....you can, but use OUR cover.

 

Turbochargers are a personal favorite. 6.0 turbo, in the box, comes with a fucking tag that says "DO NOT DISASSEMBLE HOUSING" Yet Ma Ford says hock that fucker apart.

 

And now this. An oil cooler, you can split into pieces, so here we go, let's do that, too.

 

Like I said before, We've got a few of 'em soaking in the varsol tank cleaning the layers of filth off of them so we're prepared for the coming repairs.

 

This band-aiding shit is really starting to grow tiresome. What next, it gouged a cylinder wall, so we're gonna have you weld it up, and then grind it flat, then ball hone it?

 

Going back to plastic injection on worn out balljoints and front end components?

Aron, I don't mind rebuilding or servicing assemblies like this. Remember, we have largely gotten away from that in the last 10-15 years. I just don't think that I should have to take it in the ass because Ford is attempting to save money. If they want to save costs by replacing only the bad parts in a component that is fine but give us a little bit more time to do it and take a little care in doing so. Here's a good question: say the adapter or the cooler body is corroded and cannot be reused? What kind of flaming hoops, phone calls and prior approvals are we going to have to go through to get an oil cooler assembly under warranty? More wasted time.

Thats exactly the reason I haven't been tossing the old coolers out, I had a feeling something like this was coming and started setting the coolers aside last summer. If I need a cover I have one.

We have a number of cleaned oil cooler housings from customer pay jobs that I would just grab one of those and pitch the bad one during the swap. It would be less hassle. Stock up your supply now.

I would say for *each* tech you might only want two housings. Keep one clean and ready to go when you need it and a spare in case you get one that is screwed up or you damage it prying the heat exchanger out of it.

I don't disagree with rebuilding these, but I do disagree with we get to take it in the pooper for it, and I am wondering where it's gonna stop.

 

And there is NO flushing these things. Me and Shlep have had 3 or 4 of them in constant rotation in the varsol tank trying to flush the shit out of the cooler. No workee.
