I picked up a new style primer pump today from Napa as the old one leaks. I figure I need to get it done before I get the car on the road anyways... I'm not seeing an easy way to change it... Seems there's crap all around the base where the hex should be. Is there an easy way?

Also, the oil cooler, I need to get it out. I've taken off the fan shroud and removed the two nuts. The lines are disconnected. Do I need to remove the entire radiator assembly to get the oil cooler out?

Thank you in advance.
