oil cooler issue

[Warhead]

I bought a 2003 dmax for a project truck recently, it had a broken bellhousing and adapter plate and a bunch of other small quirks. I fixed most of the small stuff and sent the truck over to a buddies shop to do the bellhousing as I'm tied up with other projects. Anyway he called me today and told me its got a coolant leak from a crack in the oil cooler elbow (which I had him order from GM) the problem is apparently you cant change the elbow with the adapter plate installed unless you remove the oil cooler. He talked to GM and they told him they no longer sell gaskets for that oil cooler because they upgraded the part and that I need to buy the new oil cooler and gasket set.

So I have three questions here:
1) Can I source a gasket set for the original (2003) oil cooler setup?
2) Can I install that gasket set and new elbow without taking the adapter plate back off?
3) Any way I can install the elbow without completely removing the oil cooler?

Thanks guys!

Rockauto may have the part.
It's a PITA but yes it can be done.
Possible, it s in a very tight spot.

Well I unbolted the oilcooler and pulled it away just enough to get the elbow in the back side. That job sucks but it only took about 90 mins all told.

After topping off the fluids I fired up the truck and found its now leaking from the waterpump outlet (front of the pipe feeding the oil cooler). I figure it jostled the gasket a bit when I pried the cooler out. Its a very small leak but I want to sort it out asap. Anyone know If I can possibly change that gasket with pulling the waterpump? or is this going to be a full waterpump job?

I've done it twice so I is possible.

Merchant automotive has the gaskets you need sold individually.

You've done the pump outlet gasket twice without pulling the pump?
It seems like it would be impossible just because it doesn't seem like I could remove the outlet pipe itself so how do you clean the gasket surface?

Or is it an o-ring?

no, seans done the elbow gasket twice.

you need to pull the oil cooler again or pull the water pump to fix that seal you talking about on the water pump outlet. Mechant has the elbow gaskets you were looking for.

Oh you mean the big o-ring where the pipe comes from the water pump into the oil cooler. Yeah James is right you have to pull the water pump or oil cooler. I would pull the water pump myself so you only have coolant going everywhere instead of coolant and oil, jmo
