oil cooler

[green97gstspyder]

what oil cooler is best to run? is it the side mount or the round one that mounts
where the oil filter is? or can you run both?

my car originally had the side mount but i bought a motor that had the round one. if i use both how do i plumb the round in? i believe this to have water run through it. correct me if i am wrong. thanks

We need to know what block you have. 1990 6 bolt motors use an air cooled cooler only. Now for a 7 bolt motor you could use the evo3, 8 and 9 air to air coolers. All the rest of the 91-99s use water cooled units. A 6bolt external cooler wont work on a 7 bolt and bice versa.. In my opinion i would rather have an external cooler. I hate my stock watercooled piece...

i have a 6 bolt motor but have oil filter housings for both styles i mounted the air cooled one which came off my other 6 bolt. will this be suffcient?

Yes, it will be sufficient for cooling the oil. Better than "cooling" the oil with 210* water and risking oil contamination when the cooling ring cracks.

Hi Wes,

Sorry to bring up an old thread but how common is it for the cooling ring to crack on these? I am looking at options for additional cooling and probably going to go with an external oil cooler but I would like to keep the stock water cooler as well.

You can't keep the stock cooler. You will have to change ofh's.

It has the fittings for an external cooler. Why can't I run it?

If it has provisions for the air cooler, then NO it is not the water cooled one.
It's either one or the other. You can't have both.

Are you confusing factory allen plugs for oil cooler provisions by chance?

The only time they crack is when some gorilla decides he/she needs to over tighten the filter.

I see. So those factory allen plugs, you can't use those for AN fittings etc. Wth are they for? Sorry, I'm still learning the ins & outs as I go here.

The Allen plugs could be for a different application other than a DSM, I don't really know though.

The one I pictured is the one you would want if you wanted to ail cool your oil. (If you still have the seven bolt)

The allen plugs are for sensors. Used one for the low pressure sensors last one I installed. And it'd be stupid to send oil through external cooler and cooler it to 170°or less(example only) then through a coolant cooler and reheat it to 212°.
Plus the water cooled one as an extended filter stud that is removable. The evo(one pictured) used to install external coolers the filter stud is cast into the ofh and isn't long enough for the coolant cooler.

The large allen plugs are there because the manufacturing process required drilling of the casting. After the holes were drilled, plugs were inserted to seal the holes. You will find the same plugs in your head and block.
