does anyone happen to know the correct size of o-ring to use on the st6.3544m engine tu70140u-xxxxxxx. the o-ring thats at either end of the engine oil cooler segment.
thanks

i may have oil cooler problem, oil leaking into raw water. looking for picture breakdown , p/n's etc. where i might find the stack tube assy, any info would be helpful. also gasket set for the multi cooler
