Engine Oil Cooler Upgrade: Add 2 quarts! (SAS guys you'll want to see this)

Power steering cooler? its on the passenger side... I didn't know this when I posted this but I looked up my VIN with the VIN decoder and I have the z88 (iirc) towing package and I think that comes with a transmission oil cooler. I think that's what I have. I don't know why one would need a power steering cooler but maybe it was an option. I would think power steering would be on the driver side since that's where the pump and steering gear are located.

Probably your power steering cooler. I have one behind the grille on mine.

And If anybody is ambitious, you should be able to run the vertical filter adapter with one of the newer "short" filters. All the GMT800's I've seen use a filter that is the same diameter and seal, but about 2" shorter. Should clear the driveshaft, and it's not like you need clearance for the shaft to travel.

IIRC GMT400 trucks used a standard thread, while GMT800 trucks use a metric thread.

Pass side, infront of the radiator is trans, driver side infront of radiator is engine oil, driver's side tall and skinny next to radiator is power steering cooler.

PS cooler is needed mostly for the hydroboost setups or any hydraulic setup run off the pump.

Very Nice!! Did you have to Cap off the ports from the old lines or just leave them open????

I left the original cooler ports open.

What did you use to seal the mounting bolts on the oil cooler? I cant seem to find those washers with the seals in them anywhere.

Here's a funny question. How long do you have NO oil pressure after starting your engine every oil change with all this setup?? 4 Seconds at least I imagine. Something to remember; after every oil change, unplug your coil wire, and crank your engine for a good 15 seconds... This will put oil back in your lines so your pistons aren't moving and 1,800 revolutions per minute without oil pressure for any amount of time. Do this as well as fill your filter up before installing.

Definitely going to keep this mod in mind. Doesnt look too hard or expensive. Hardest part will be finding the cooler for me as we dont have alot of parts vehicles up here! I might have to order one or have someone send me one.

tons of trucks at my local yard with oil coolers might snatch one

Just make sure the bottom end is in good shape on your donor truck. If the oil is contaminated with metal frag it's all through the cooler and damned near impossible to get it flushed clean again....
