The 1st pic is a Caterpillar 6060FS shovel radiator being pressure tested in our test tank. The 2nd picture is a 454 Chevy big block in the line hone that we just finished machining for & installing 4-bolt splayed main caps to. & the 3rd pic is an all metal radiator we built for an Acme Sykes portable water pump that originally had a plastic tank radiator that failed. Thanks for looking!!
