    Just got the ole girl back from a long inframe overhaul. New, aftermarket head, liners,pistons, bearings, etc. I've been running her for about a month and just had the oil cooler fail. No oil on the dipstick and the radiator is FULL of GRAY GOOO. My question: Is it typically normal to have had the oil cooler replaced during an inframe?

    I usually would replace the oil cooler during inframe as a lot of stuff have been removed which allows easy access.

    My boss is a bit on the cheap side. I wasn’t able to replace the oil cooler in the truck I use.

    Cooler failed 35,000 miles later. So the twin turbos and a lot of stuff had to be removed all over again.

    All for a $700 part.

    I’ve got one Acert, and I dread doing anything on the right side of that engine for that very reason. Last time I had it apart for an exhaust stud I changed the oil cooler while I was there.

    I just replaced my oil cooler due to oil in coolant 3-4 months ago. Truck is now in shop for a rebuild and it will get a new one again.

    We also have only one ACERT too.

    I don’t find it bad doing everything on the right side.

    The first time was a challenge as the turbos can only come off or be installed in a certain order. Looking at some other ACERT trucks, some look easier to do since they have more under hood room.

    I’ve done the removal and installation enough already to have gotten better at it.

    I’ve also modified the exhaust manifold to use stainless bolts instead of studs after the last stud broke off.

    Since then, I’ve now been able to get the small turbo off without having to remove much stuff to get to it in a certain order.

    When the manifold had studs, I think the large turbo and many parts had to come off first before the little snail can come off.

    Inframe is a pretty broad term. Some folks consider new bearings and pistons/liners an inframe, others include the head, turbo, water pump, oil pump etc.

    You can literally rebuild an engine 100 different ways. That said I'm with the folks above - you're already in there and you're already 5 figures into the job, what's a few hundred bucks more?
     
    Shawn2130 and kranky1 Thank this.

    I say no. Just because it's not a hard item to replace any time. You don't need to pull the engine apart to do it. Also it's not a high failure item. Could last the life of the engine.
    I wouldn't just automatically put a new one on at inframe without knowing when it was last replaced

    It should be a duh thing to replace in an inframe but somehow isn't.

    I guess I just assumed it would be replaced and was a little surprised when it wasn't. I don't OWN the truck it's 1 of 2 company trucks. My input is always listened to and usually acted on but I don't have the final say. I decided not to ruffle feathers and just go with the flow when I noticed it wasn't replaced. It's not always fun to say "I told you so" when I'm the one in the unemployment line. While it is a very easy replace on that motor, it SURE MADE A MESS out of the cooling system that will cost a lot of labor to clean up. Oh well, live and learn. Thank you for your replies...
