I believe older oil coolers are 1/2 NPT.

Like Brad said, the old ones were 1/2” npt. You don’t get more than 3/4 of a tune before the 1/2” npt binds to high hell

Don’t you dare ask me stupid questions!!

Lol yeah you could but it would be too big for 1/2 npt then.

Couldn’t find a flanged bolt in that length so you may have to buy GM bolts with the cooler if you want them all to match or change them all out so they match
Just to let you guys know who plan to purchase new bolts. I was able to order these through my local fastenal for about 15 dollars. For the 5 bolts James gave the measurement for and order an 8mm x 1.25 20 mm long for the third new hold on the cooler outlet adapter.

Update. Ordered the adapter off of Amazon that was mentioned. I don't think it is going to work. Either mine is wrongly machined (the fitting) or the cooler is not perfectly flat on the exterior where the fitting sits. Either way the copper crush washer is unable to make full contact with the entire fitting. I still have not been able to identify the fitting used. The closest thing that I can find is a NWD zero leak fitting but it uses an o-ring along with the taper that these fittings seem to have on the top of them. I may try and reach out to a machine shop to see if they can make one. Will update again... if that proves successful.

Boy this cooler makes a difference. Took the truck out for a maiden voyage and romped on her pretty good. Oil never went over 195 and man it cooled off fast when the coolant would drop from 195. Usually I see 195-200 and holding under the same conditions. It would hold 180-185* otherwise which again is cooler and staying right on coolant temp. I’ve taken the air to oil cooler completely off and have a trip planned end of April so it will be a real good test them. It was 109* today when I was running around. She’s staying cold

How cold is to cold for engine oil when under operating conditions like this. And is it solely because of the fact that it keeps pressure higher or because it impedes flow..?

Did you notice much of a difference in how the coolant temps were running?

im not going to see that until towing. i also have much more cooling capacity than a stock truck so that will not be a fair comparison.

Glad to hear this is working awesome! From what I've read, you're seeing lower temps with the 2020 cooler than you were seeing with the factory cooler and external cooler, is that correct?

I'm excited to see the towing results.

with the fan on, on the external, they are about the same but with a faster reaction to cooling with the 2020 cooler (as to be expected). its a question of how much it will now load the cooling system with heat.

there is a wheeling trip next weekend i may tow my tracker up for (up in payson, toughest hills in az to tow on) so i can see how a light load is with it.

10-4, I am thinking I can get by with just the 2020. Hottest I see is ~95f ambient and we don't have tons of hills. For under $250 I think its a worthwhile upgrade to help keep the oil cool.
