oil cooler, is it important how its plumbed?
hi, i have managed to get hold of an oil cooler for my saab, its off an MG metro 6R4! which is cool as can say at least one bit of my car is from a
Group B rally car!
anyways i am wondering if it matters which way the oil flows through the cooler, is it more efficent a certain way? also does it matter which way up
it is?
to have good air flow through it, how much clear space should thier be behind it? in peeps experiences?
many thanks

You want to place it so the inlet and outlet are at the top or the oil will drain out overnight.
That looks like a huge thing, unless you are pulling trees out of the ground I suspect it will be complete overkill and overcool the engine.
That aside getting hoses to suit will probably make your eyes bulge, depending on space etc I suggest you fit it to your car then get someone to make
the hoses in situ. Its then their responsibility if the crimp them in the wrong orientation so get quotes before you even start, these things do not
have a lot of flex.
When I had some made I got a lorry fitter to make then on the side... You need someone with the correct crimping tool.

It shouldnt matter which way you plumb it, and you can mount it with the unions at the top or bottom, although bear in mind if they are at the top
then you'll have to disconnect and tip it over when you want to completely drain the oil.
As to the gap, if radiators have to sit in front of each other, they work best if they are as close as possible together or even touching. If you
leave a gap the air will be turbulent in the gap so the air won't flow through as well, so cooling will be affected.

i admit its a bit big, its about 10 inches square! i plan on having a thermosatic sandwich plate so i shouldn't be overcooling the engine.
also i am having to mount the coolant radiator behind the engine due to lack of space, hence getting an oversize cooler to make sure the engine will
stay cool! the fittings are pretty large, i hadn't thought about the cost of hoses! does anyone have a source of large fittings?
also the gap between the engine and cooler won't be great, a few cms at best, i can probally mount it to one side so it is not completely
blocked by the engine

thinkautomotive.com will make you any type of oil cooler hose and they can supply the sandwich plate too.

Great way to knacker an engine over cooling the oil, not a good idea to fit an oil cooler to a road car without a thermostat even worse when the
cooler is about 4 times bigger than is actually required.
Oil temp should be slightly higher than the watter temp to avoid condensation of water and acids in the sump and valve gear covers.
