I have a '71 2.2 motor that I'm going to put into my '72 coupe. The "on the motor" oil cooler from the '71 is threaded for a hose, whereas the '72 oil cooler I have has more or less a hose barb that the hose slides over and is hose clamped on. I have the correct oil cooler setting on a shelf in the garage but it's really filthy on the outside. Since I don't know how it's been treated (it was laying in the front trunk when I picked up the car) I'm concerned that it could have a small amount of grit, dirt, what have you in the cooler, which needless to say wouldn't get along with the interior of the motor very well. Does anyone know a surefire way to flush one of these out? I need to sort this out so I can get it on the motor and get the motor in the car. Thanks!
