OBS oil cooler

[GilroyRacing]

How much of a pain in the ass is it going to be to install new o rings and gaskets?

 

[POWER-STRUCK]

it can be done with basic tools and a ratchet strap

What made me ask is all data is saying you need to undo the motor mount.... They are saying its a 3hr job.

 

[POWER-STRUCK]

will fit out on a 4x4

Mine is a F350 4x4 CC 8' bed

Remove the fuel lines from the motor makes life so much easier

I also tried my best to clean the cooler out.

 

[POWER-STRUCK]

generally get rebuilt due to oil leakes but you can clean the cores while you have it apart, i can assure you that the job is not too hard just messy

Was really easy. Looked hard at first.

I did mine a little over a month ago. I started off by draining the coolant and oil, then removed the oil filter. I pulled the drivers side front tire off and the little splash gaurd thats between the frame an inner wheelwell. After that, i removed the block heater cord, an then the actual block heater itself from the rear flange. There's 2 bolts on the front "header" flange of the cooler, an there's 3 bolts on the rear "flange" (it's also what the oil filter screws into). Then you slide the whole thing towards the back of the truck an it comes out pretty easy without removing anything else other than what I listed. After you get it out of the truck, both of the "header" flanges slide off either end an you'll then be able to clean it up an swap the o-rings. I had everything done up till this point in about a half hr working by myself. The biggest b!tch is getting it back together because with the new o-rings it's a pain to get it compressed enough for all the bolts to line up. I ended up using a hydrolic press an carefully pressed it back together because I couldn't compress it enough by hand. After that, slide it back in place, get the front 2 bolts started but leave them loose, then put the rear 3 bolts in, tighten everything down, an fill her back up with fluids an your good to go.


It was a pretty easy job to do, other than getting the ends compressed enough so that I could get the bolts started. If yours has been leaking for awhile, do yourself a favor an get some type of degreaser an hose the driver's side off real good under the exhaust manifold and the surrounding area. Otherwise it's pretty straightforward.

When I did one last time I thought I was going to have to use a press to get it back together with the new o-rings but I ended up just using hydraulic assembly lube and it made it slip right in a lot easier than I thought was possible. Use good lube.

Thanks for all the tils

At what point does the cooler get replaced as compared to re-sealed? I need to at least re-seal mine but if there is an advantage to replacing the cooler I'd rather do it once.

 

[POWER-STRUCK]

generally just reseal them unless they have a hole rusted in them, in few instances they can have an internal core leak
here's the parts you need http://powerstrokearmy.com/forums/showthread.php?t=28071

Is an oil change and coolant change necessary?

I only have 2k on the oil and 2 yrs (9k) on the coolant.

You have to drain both, I guess if you drain into a clean bucket or whatever then you'd be able to re-use it. That's up to you

I won't reuse fluid, once it comes out of the engine it never goes back in. Guess I'll try to wait. I'm not getting any drips just seeing some seeping.

I used a ratchet strap to compress the end caps back on. To hold the entire assembly together for install I used a small nylon strap, once bolted up just remove the small strap. Also use ford parts not international is my recommendation. Had a problem a number of years back sealing the front cooler header to block (IH gasket was not exactly the same) and I ended up over tightening the header bolts and cracking the front aluminum engine casting. Major pita....
