Anyone know what size of fittings go into the rad for the oil and trans cooler? Looking to plug mine. Truck is a 91 Silverado.

sorry only posted the trans cooler fitting. the oil cooler is a 3/4-18 uns 0-ring. at the radiator

any are you just plugging the holes so dirt doesn't get in? it will be hard to find the oil cooler fitting. i would just use a plastic style cap if so.

Oh ok, ya basically. and I really don't want any of the old residue flying around in my engine bay. Don't know if it would but I don't want to see, not a mandatory thing I do but I might aswell do it.
