I have added an engine oil cooler to my 99 Silverado.
Upgraded to an all-aluminum radiator with cooler tank.
Bought the lines, clip and bolt to motor, plastic clip to shroud, and connectors to radiator.
Oil pressure will drop 10 psi, and need a 1/2 quart more.
Route lines to the back, above the electrical wires, at front of motor.
The spring and seal should come with the lines, I ordered them, from a GM dealer.

I bought it, a few years ago, when Compnine.com showed parts diagrams for free.
Went to Gmpartsdirect.com, looked up engine oil cooler for a 2500 truck.
It showed $80. for the lines, $5. for clip. Shroud clip was hard to find.
Silla all-aluminum radiator was $200.

The two lines are connected to a metal block, that bolts to the engine, above the oil filter.
 
It actually bolts to the oil pan iirc and Eddeh I know about those adapters but I want Le stock one

I'm questioning the need for oil cooler...

But I'd just buy a CNC plate adapter that replaces blockoff on drivers side of pan (where most turbo setups use as a feed) with AN fittings and line and just run to remote mounted small finned cooler behind bumper if I were to do it. Do not want shared radiator with coolant, oil, and trans fluid.
Most cases I do prefer OE setups, but this isn't one I'd personally purchase.

What brand radiator? Silla? Not familiar with it. Is it 28" wide, or 34", or?
I've often considered getting an aftermarket all aluminum radiator...
 
I'm ok with adapter, I just want to know where to get one, I'm trying to add an accumulator without a sandwich adapter

It's a 34" radiator.
Coolant temp is cooler,
Winter temp is 170* town, 180* freeway.
Summer temp is 180* town, 195* freeway.
Interior heat is luke warm, will reach 120*.
Great upgrade, no concern about overheating.

Why do you have different operating temps depending on season? I've never noticed a difference either way.
Did you used to overheat with the OE unit?
 
If the sensor is near the beginning if the cooling system and the thermostat is at the end, that could be why you'd see a difference in seasons

Never had an overheating issue.
Temp on the 28" radiator would be 195*, all seasons.
The all-aluminum radiator runs cooler.
I was concerned at first, changed the thermostat, flushed the coolant, same temps.
It passes smog, no difference in gas mileage.
I still have a mechanical fan, no e-fan upgrade.
