Have any of you ever adapted a later model style oil cooler to your engine that has engine coolant routed through a heat exchanger mounted to the oil filter housing?? I asked about this on an Oldsmobile forum, as I am considering using it on my Cutlass that I drive on long trips through the mountains. I like the idea that this system will also heat up the oil faster when cold, and not have any external oil lines running about. If I could adapt one to the Olds, I may do the same thing on my Pontiac as well

Not sure if it matters, but Chevy dropped them on the Corvettes in 1992 when they switched to Mobil 1 synthetic, Chevy didn't feel they were needed.

Some threads on the CorvetteForum noted it was more to warm up oil than cooling it.

And our motors are a little tight space wise.

So......maybe eyeball the Hayden catalog for a more traditional oil cooler.

Hayden did introduce a transmission cooler that bypasses cooling until the fluid warms up. Kinda slick.

Don't see it yet for engine oil, but didn't search much either.

Also - "plate oil cooler" are used in OEM designs, fairly small and efficient. Less space to connect between the oil filter housing.

One example - the install directions show the size, pretty compact.

Little food for thought, this is what GM uses on late model Corvettes - plate design.

I use an sandwich plate adapter on my LS2 05 GTO to adapt the remote by pass oil filter I use. The aftermarket adapters usually are available in different port sizes depending if you're running a small diameter line, or a larger diameter line for an application such as an cooler/full flow oil filtera that needs more flow.

Many of the sandwich adapters have a pressure port as well as a return port to keep both lines of a cooler, or filter plumbed to the same adapter. No return needed to return oil back to the oil sump.

Oil coolers are also available with thermostats similar to a coolant thermostats that stop the flow of oil when the cooler isn't needed due to load, or ambient air temperatures.

Glo Shift has a pretty good selection of sandwich adapters for all applications. I just bought one for the 3.1 engine in my 99 GP to adapt a by pass oil filter to it.

Amazon sells Glo Shift adapters with no shipping charges, Glo Shift needs a $50 minimum to waive shipping charges.

Amazon also has thermostat adapters for oil coolers.https://www.amazon.com/s?k=ls+oil+co...l_12s97ji989_p

This is what I was thinking about

86-87 Grand Nationals used the sandwich style adapter. Even when plumbed to a bar & plate style cooler, I didn't see much difference in oil temperature on a mild high 10 second street car. Factory setup plumbed to the radiator which had an oil cooler in the passenger side tank. It's often eliminated when the stock radiator is swapped out for a radiator that doesn't have an oil cooler built in.
